You're like my best teacher! This video is Superb. Methodical, simple and clear, no fancy cr#p, no aggrandizing, just the facts. Thank yuou so much for it!
Thank you Sir. You just made my day. You gave me a ton of insight on on a painfully factory stock I'm not kidding AM/FM 8-track player and a hang ten high beam foot cover. Its a 1977 f150 4-speed. Numbers matching truck so I'm going to rebuild it. Thank you again you just made my day.
I’m only watching this out of curiosity lol my trans whines in gear (mainly 1st and 2nd) but that’s literally all Chevy S10 manual transmissions ain’t it
Thanks for the explanation! My 2000 GMC Sierra's manual transmission ran dry about 10 years ago and I was able to limp to AutoZone in 4th gear because it was the only one that continued to work. I filled it with synchromesh fluid and was able to drive it again, but it had developed a whine in every gear except, of course, 4th....and now I know why. It also has a loud rattle whenever the clutch is disengaged at idle. I've been told that's the throw out bearing making noise. I've lived with it ever since, so I guess the old saying holds true - "GM vehicles run bad longer than others run at all."
Is it still running and making the noise? Same thing happened to me last weekend in my 2000 silverado. Same exact symptoms as you. Debating on replacing it now.
@@TigerHoover Yeah, it's still on the road and still making the noise. I figure I'll drive it til it dies, then replace it. With truck prices what they are these days, I'd much rather pay for the repair.
@@JohnGeldreich Hey, thank you very much for replying. Your original comment was from two years ago, and they still really help people out (like me). I agree with what you said about rather paying for a repair. I filled mine back up with synchromesh too. Interestingly, I called a bunch of transmission shops around town and a lot of them wouldn't consider rebuilding the transmission. I was told by all of them it's because it's old, the design is a pain to work on, and it's cheaper to go with re-manufactured. I'm debating buying a re-manufactured one and installing it myself, although perhaps I wont be in too much of a hurry since yours lasted so long.
@@TigerHoover Yeah, I think remanufactured is probably the way to go. Lots of shops have no idea how to rebuild a transmission. As for what you do in the meantime, you should find out why it ran dry. In my case, or so the shop told me, a couple of bolts had worked loose on the top near the gear shift and compromised the seal. They said they just filled in the gap with gasket maker and tightened the bolts down. It's held ever since. I changed the fluid again maybe 3 years ago, and today, because of this conversation, I decided to crawl under and check it again. Still full. Good luck!
Thanks, now I know where to look at on my w202! It makes a very interesting whine which I thought to be from the supercharger and the bypass valve(and thought it was normal). Yesterday though, I noticed that it's actually constant, just harder to distinguish when I'm on the gass. In neutral it's still there and directly related to speed, so it's gotta be a wheel bearing... I've had this car for just under half a year now and I keep finding evidence of negligent ownership from the previous two guys :D
Wow man! The counter shaft may have a different number of gears and direct drive might be a different selection but this video of noises attributed to a non shifting counter shaft transmission was pretty great. Thanks
This is a great video. Never knew how much could be diagnosed by listening for the different sounds under different conditions. I do believe now the sound I'm hearing pertains to the pilot bearing, but I would like to know how a bad pilot bearing actually sounds.
@BYUI AutomotiveVideos Thank you for sharing. Very educational video and extremely helpful to get closer to diagnosing a loud knocking sound I’m experiencing only while in 5th gear. I have a 1999 F250 Super Duty 4WD with the 7.3 turbo diesel V8 motor and the ZF6 transmission. Everything sounds normal and all shifts are smooth until I shift into 5th. Even though it shifts into 5th smoothly, once the clutch is fully out it sounds like an M60 machine gun while accelerating in 5th. As I reach the speed limit and let off a bit the rapid knocking sound quiets down a little but once accelerating again, ie passing a vehicle it gets loud again, and I mean real loud. I’ve ran it through these series of tests, all starting the same, steady speed of 75MPH with 5th gear engaged. Here’s the different tests and outputs: 1) If I accelerate hard, I have no slip at all and the torque is incredible making accelerations extremely quick, but the rapid knocking sounds get extremely loud, head turning loud, duck and cover loud from people even remotely close to my truck. 2) If I completely let off the skinny pedal, while leaving the clutch engaged (essentially engine braking/coasting with clutch out and still in 5th), the rapid knocking sound gets quite a bit quieter but nowhere near silent. 3) If I push the clutch in while leaving it in 5th gear (coasting with clutch in), the sound completely goes away. 4) If I push the clutch in, pop it in neutral, and let the clutch out (coasting with clutch out and in neutral), again the sound completely goes away. Would that mean it’s the counter bearing for my 5th gear? Any help appreciated and thanks in advance. It’s so bad I try to stay off the highway to just avoid 5th.
@BYUI AhtomotiveVideos what's the verdict? After posting this post I cruised it out to the ranch and parked it (fully enclosed garage). Now I'm looking at cobwebs and scorpions. All i want is to get Beastmode back on the road (without the artillery sound in 5th). What is is the issue here? Full tranny swap? Rebuild? Please help. Thanks.
I watched this video before dropping off my NSG370 for a rebuild. Although two different transmissions, very similar in mechanical design. I isolated a humming noise to either the transfer case or transmission with the vehicle on jack-stands via mechanics stethoscope and also ruling out driveline by removing front and rear driveshafts independently. Following, I rebuilt the transfer case and the noise continued. The noise was through all gears but more prominent in 4th, 5th, & 6th. The noise was also consistent with clutch disengaged or rolling in neutral. I told the transmission shop I was 99% sure it was the main output shaft bearing and sure enough it was toast.
I get a grinding noise when I take off on first, but I don’t feel it through the shift knob. I suspect it’s the front differential. It happens when I add a bit of gas at the biting point. I don’t feel anything on the clutch pedal either. Also, my clutch pedal sometimes goes stiff.
that was a nice informative video. I was hoping it would help solve my problem but it didnt. It did give me a better understanding of what it might be.
I know this is quite the 'niche' video, but i would vote this is the best video on youtube. so simple and yet informative. use a little brainpower and solve your issues.... and i think my main bearing is bad on my 240sx..... only noise is on load 40 or so mph while coasting or decelerating in gear.
Thanks for the HELP!! I have the W56 manual transmission on my 1985 4runner with noises in the 1st 2nd and 3rd gears going forward from stop.... 4th and 5th and in neutral while coasting, no noise.
My FRS recently had a transmission issue I can't lock into any gears except for 5th. And in neutral it has a knocking noise from inside the trans when I grab 5th the noise goes away so I know exactly where to look this video definitely helped me🙏😏
Great video. Can you explain gear rollover noise and how that would be differentiated from input bearing noise while in neutral and clutch pedal released?
Bearing noise is usually a constant noise, gear roll over noise or gear chuckle can be a slightly choppy rattle type noise as the main shaft and layshaft gear teeth chatter back and forth. Try changing the gear oil for fresh correct weight oil first, gear oil does wear out of grade over time. Fresh oil often dampens the gear chatter down.
There's also another noise associated with gearboxes that I only become aware of after installing a heavy duty clutch in a 4x4, it's called "rollover noise" or neutral gear chatter. Apparently it's common in sports cars and some 4x4s straight out the factory which creates warranty issues. Apparently it causes no damage what so ever. It is however annoying. Thinking it was an input shaft bearing at first I decided to remove the gearbox and have it fully rebuilt to replace all bearings (because I'm thorough) it turns out my gearbox (through proper maintenance and use) was like brand new. I'm now left with neutral gear chatter.
That noise is, from what I understand, the power pulses of the engine causing the gear teeth between the input shaft and countershaft to chatter back and forth between engaged and disengaged, just across their backlash distance. When you're under power in either direction in gear, that backlash is taken up because of the force pushing all the gear teeth into mesh.
@smatt9993 - Thank you for mentioning "rollover noise or neutral gear chatter!" I did not know this was a thing and was thinking an input shaft bearing was bad. I have a 1989 RX-7 with 47k miles that has had a loud growl in the trans in neutral with the clutch engaged (pedal up). The noise completely goes away with the clutch disengaged (pedal down). The noise has been present since new, the past 34 years (original owner), but the trans works great. I changed to Redline MT-90 synthetic fluid and it quieted down a bit but the noise never went away.
Could be clurch plate dampening springs unloading & loading (they should be under load constantly when clutch is engaged), hitting the rivets, or 1 or 2 loose ..
My 1997 Mustang GT has started chirping. I hear it most in neutral. Shifts through gears fine. When I depress the clutch, the noise stops. When i release the clutch, it chirps a few times and then quietens down. Was told this is a pilot bearing? Am I correct in assuming that I should just go ahead and replace both the pilot and throw out bearing since the bell housing will be opened up anyways? I guess there is no reason not to change them both. If you could advise, I would be greatly appreciative. If not, I still appreciate your video above. I have searched what seems like THOUSANDS of forums, and I have heard it all explained 50 different ways to Sunday. Your video actually allows me to see it function and to compare it to the symptoms that my car is presenting me with. Thanks again!
Skipped over one bearing that has given me problems before, primarily in the Ford SROD four speed. The pocket bearing, that's a little needle bearing in between the input and main shafts. In this case, it would make noise in every gear except third (direct on this model), in one case so loud it sounded like a diesel.
Both my wheel bearings are changed and the noise have been there for YEARS. I have a clio (fwd). It has to be the transmission even if the noise doesn't go away with the clutch.
When I slow down my new range rover Evoque it started clicking noise after 750 miles from gear transmission, I took to the land rover Garage they said it is normal few land Range rover Evoque make the same noise is it true?
I have a 2007 caliber, and I have noise coming from the trans in 3rd through 5th gears. Only when the engine is applying power to it. Neutral and clutch in, no noise. Coasting in gear, no noise. I've found very little information about this transmission online. I've seen posts about it from other people, but it's either unanswered, or never solved.
Actually the main shaft bearing is in that blue plate in the middle, not where he's pointing at in the aluminum extension cover where the gear lever is. There is a small bearing on the output shaft that serves to keep the output shaft centred but doesn't take any thrust loads (from the helical gears) like the main bearing.
@@Videoswithsoarin That's the input shaft bearings at the far right. There are 3 shafts in this gearbox. The input shaft is inline with the mainshaft. The main bearing is in the blue steel plate, that's why it's there. I've destroyed and rebuilt dozens of these gearboxes. 😄🇦🇺
I found out what was wrong with my T56 Tremec,2 of the rear tailshaft flex coupling bolts were a little bit loose so that was probably interfering with the mainshaft somehow. I only found out when I was adjusting the handbrake shoes & checking the CV joints for play as I was also hearing a clunking sound from the rear end. At least one of the CVs has a bit of play in it but tightening the bolts up has fixed the problem so far,I'll keep an ear out for any unusual noises,the rattling noise is gone now !
My noise progressively got worse in all but 4th gear. It started with a whirring sound, and then a tick-tacking sound. After about 500 miles the racket was so loud it became clear the failure was catastrophic! I hadn't any option but to pull the pan, and when I did... The main gear on my counter shaft was mangled! So to the junkyard I went, a couple gaskets and seals later and the correct fluid I had that transmission running just like a song.
Whirring noise above 55mph only when under forward power. Disappears when in neutral or clutch disengaged or decelerating. Had multiple garages tell me this is a wheel bearing but it doesn't sound like one to me due to the fact it disappears when not under forward power.
I have a whine when accelerating only inall gears, possibly not in 4th, I have to test tomorrow. So i guess it might be an outputshaft bearing, thank you for the learning!
check your clutch fluid guys, mine was leaking and causing the clutch to be constantly engaged. couldn't get into gear hardly at all. I parked, put it in neutral, depressed the clutch, and pushed the shifter into 1st as far as I could push it and the engine bogged down -> reverse clutch slip. 3oz of dot 4 brake fluid put me back on the road in about 5 minutes.. still haven't bled the lines, but there's no extra play
I was looking into other transmission issues and I accidentally diagnosed one of the other issues on my car. Transmission whine in all forward gears except for the 4th! Countershaft bearing/bearings.
Just had my 5 speed NV3500 fork and throw out bearing replaced. Prior to replacing the pedal was very hard to depress. Mechanic said fork wore out. I replaced replace pressure plate, pilot bearing and throw out bearing about 15000 miles ago. Less than a month from having throw out bearing and fork replaced making a loud screeching noise while depressing the clutch in neutral. Also noticed clutch is getting harder to depress.
It is either bad synchros, or a bad selector on the shift mechanism. Sometimes the selector forks stick and will not go in, and that could mean that they have burrs, bent, no lubrication, debris blocking them, or all of the above. Bad synchros are similer in feel to a bad fork, they may have debris blocking them from engaging, they could have burrs from shifting without clutch, or they could be running dry. An unlikely but possible source of your trannys ailments is a bad shift gate, if the transmission selector has a bent shaft, or is acting like it wants to slip out of the selector all together, it could also be that. Tell me if what you are experiancing matches one of the ailments I described, we will get to the bottom of this. We will get your car sorted;)
When rolling down hill with the engine shut off, I hear a weird scratchy noise (kind of sounds like really worn break pads) in all gears and neutral (clutch DISengaged) // When stopped (engine on, clutch engaged) I can still hear the noise. It goes away when I disengage the clutch, and it gets louder if I give it gas // these noises came suddenly one morning and have gotten slightly louder over the last 2 days.
09 Jeep Jk manual. So after shifting from a dead stop or into any gear there is like a crackling/rattle noise when I give it gas after I shift . The more gas I give it the louder it is. Its really bad if i start out in 2 or 3rd gear from a dead stop. Maybe a bearing issue. It does shift good and it never pops out of gear and I have changed the trans fluid after the problem started.
I hear a clinking noise in or around the transmission on my 5speed topkick. noise goes away when clutch depressed, and is present in any gear when clutch is engaged.

I'm always surprised to see how small the transmission actually is. Great video, thank you.
Yah without the bell housing really brings in perspective of its size.
they got even smaller now they use 2 shafts that hold the gears for front wheel drive to make them shorter.
You forgot the main noise associated with manuals: pure joy
Yeah I moan when I shift gears
I hope I transition from the learning phase to the enjoyment phase, I can drive it on the street but my shifting is awful and clunky
@@the_rumblemaster1375 It just takes time, you'll get there eventually, I still somewhat shift kinda clunky, mainly from 1st to 2nd

Both my wheel bearings are changed and the noise have been there for YEARS. I have a clio (fwd). It has to be the transmission even if the noise doesn't go away with the clutch.
You are so knowledgeable, Brother Spratling. Thank you!
When I slow down my new range rover Evoque it started clicking noise after 750 miles from gear transmission, I took to the land rover Garage they said it is normal few land Range rover Evoque make the same noise is it true?
Great Job On The Demonstration
I thought this was Colin furze from youtube
Thx 4 that video 👍
I have a 2007 caliber, and I have noise coming from the trans in 3rd through 5th gears. Only when the engine is applying power to it. Neutral and clutch in, no noise. Coasting in gear, no noise. I've found very little information about this transmission online. I've seen posts about it from other people, but it's either unanswered, or never solved.
Actually the main shaft bearing is in that blue plate in the middle, not where he's pointing at in the aluminum extension cover where the gear lever is.
There is a small bearing on the output shaft that serves to keep the output shaft centred but doesn't take any thrust loads (from the helical gears) like the main bearing.
i can see the bearings on the ends of the shaft bro its not in the blue plate. the output shaft bearing looks to be in the blue plate

That's the input shaft bearings at the far right.
There are 3 shafts in this gearbox.
The input shaft is inline with the mainshaft.
The main bearing is in the blue steel plate, that's why it's there.
I've destroyed and rebuilt dozens of these gearboxes. 😄🇦🇺
What a great video!!
Thanks For Explaining it Sir :)
I had to figure out my release bearing by logic, wish i had seen this years ago when i was learning!
Fantastic video 👍
Very many thanks.
Great video. ☺
I found out what was wrong with my T56 Tremec,2 of the rear tailshaft flex coupling bolts were a little bit loose so that was probably interfering with the mainshaft somehow.
I only found out when I was adjusting the handbrake shoes & checking the CV joints for play as I was also hearing a clunking sound from the rear end.
At least one of the CVs has a bit of play in it but tightening the bolts up has fixed the problem so far,I'll keep an ear out for any unusual noises,the rattling noise is gone now !
My noise progressively got worse in all but 4th gear. It started with a whirring sound, and then a tick-tacking sound. After about 500 miles the racket was so loud it became clear the failure was catastrophic! I hadn't any option but to pull the pan, and when I did... The main gear on my counter shaft was mangled! So to the junkyard I went, a couple gaskets and seals later and the correct fluid I had that transmission running just like a song.
Excellent tutorial I needed a refresh, now I can sort out that bmw r1100gs gearbox.
Whirring noise above 55mph only when under forward power. Disappears when in neutral or clutch disengaged or decelerating. Had multiple garages tell me this is a wheel bearing but it doesn't sound like one to me due to the fact it disappears when not under forward power.
thank you sir. my issue was towards the end of the vid👌
now i gotta find the time, place n the right tools to replace the throwout bearing 😫
I have a whine when accelerating only inall gears, possibly not in 4th, I have to test tomorrow. So i guess it might be an outputshaft bearing, thank you for the learning!
Great video 👍🏻
Thank you very good video
Thanks learned that my input shaft bearing is the problem still gonna ask if I need a rebuild as prevented maintenance
superb video !!!
This is cool!
you are a genius I have a bad bearing in my countershaft 4th gear is good the rest of the gears McCracken I thought it was a I thought I threw a rod
How much did it cost to repair?
How much was it ?
Same
Thank you!
check your clutch fluid guys, mine was leaking and causing the clutch to be constantly engaged. couldn't get into gear hardly at all. I parked, put it in neutral, depressed the clutch, and pushed the shifter into 1st as far as I could push it and the engine bogged down -> reverse clutch slip. 3oz of dot 4 brake fluid put me back on the road in about 5 minutes.. still haven't bled the lines, but there's no extra play
Thanks a lot!!!
Learning, diagnosing my car AND asmr, I hit the jackpot
2004 dodge dakota has all these sounds lmao fml tans was ran 6 moths no fluid been driving on it for 2 years so
very helpful video as I'm studying for my A3 test
Good video! I know about transmissions but I know a little more know
Nice....useful content....🏁
I was looking into other transmission issues and I accidentally diagnosed one of the other issues on my car. Transmission whine in all forward gears except for the 4th! Countershaft bearing/bearings.
Just had my 5 speed NV3500 fork and throw out bearing replaced. Prior to replacing the pedal was very hard to depress. Mechanic said fork wore out. I replaced replace pressure plate, pilot bearing and throw out bearing about 15000 miles ago. Less than a month from having throw out bearing and fork replaced making a loud screeching noise while depressing the clutch in neutral. Also noticed clutch is getting harder to depress.
Great video. All I've got is a grabby 2nd. And sometimes it doesn't feel like it wants to go into gear
It is either bad synchros, or a bad selector on the shift mechanism. Sometimes the selector forks stick and will not go in, and that could mean that they have burrs, bent, no lubrication, debris blocking them, or all of the above. Bad synchros are similer in feel to a bad fork, they may have debris blocking them from engaging, they could have burrs from shifting without clutch, or they could be running dry. An unlikely but possible source of your trannys ailments is a bad shift gate, if the transmission selector has a bent shaft, or is acting like it wants to slip out of the selector all together, it could also be that. Tell me if what you are experiancing matches one of the ailments I described, we will get to the bottom of this. We will get your car sorted;)
When rolling down hill with the engine shut off, I hear a weird scratchy noise (kind of sounds like really worn break pads) in all gears and neutral (clutch DISengaged) // When stopped (engine on, clutch engaged) I can still hear the noise. It goes away when I disengage the clutch, and it gets louder if I give it gas // these noises came suddenly one morning and have gotten slightly louder over the last 2 days.
Duran,this just happened to me today!What was it?
Sounds like input shaft and roller bearings maybe a scratched main shaft
09 Jeep Jk manual. So after shifting from a dead stop or into any gear there is like a crackling/rattle noise when I give it gas after I shift . The more gas I give it the louder it is. Its really bad if i start out in 2 or 3rd gear from a dead stop. Maybe a bearing issue. It does shift good and it never pops out of gear and I have changed the trans fluid after the problem started.
I hear a clinking noise in or around the transmission on my 5speed topkick. noise goes away when clutch depressed, and is present in any gear when clutch is engaged.
I don’t know much about newer transmissions but it appears that fifth gear on this trans is an afterthought.
