floating them is easier on that model try just upshifting around 12-1350 rpm and down shifting 9-1100 while bringing the rpm up to about the 12-1350 rpm should float easy on that 4 speed i know cause i driven a 59 bus lol

FYI: You're never supposed to press the clutch all the way to the floor when the bus is moving. The last one inch or so of clutch travel engages the Clutch-Brake. The clutch-brake is designed to stop the input-shaft from spinning under momentum from the engine spinning it in neutral so you can put it in first or reverse from a dead stand-still. The symptoms of a burnt-out clutch brake is it being difficult to put it in gear from neutral when you are completely stopped. It will grind into first or reverse even when you're all the way on the clutch and it will feel like it never wants to stop spinning and you will have to kind of "jam" it in gear to get into first.

Run it up to the governor then shift quicker. I was your age when I started driving those and newer GMCS and on to the MCI, I have about 2 million miles in them, long retired now. Thanks for bringing back memories.

Your brakes are bad period. When you put on your brakes it should just about throw you through the windshield. If they aren't that way they are bad. You need to go see Scott Crosby the bus Grease monkey.

I know this is a dumb question as it's a 4 speed but given that 1st is very low (like all commerical vehicles), couldn't you pull off in 2nd with no issues/wear on the engine? I'm assuming that the 1st gear in a 4 speed is probably higher than 1st in a 10 speed or 18 speed.

Very cool.

Public Service of New Jersey operated hundreds of 4 speed crashbox GMs. The drivers didn't use the clutch much after getting it moving in first. Up and downshifts were floated, no clutch used. Skilled drivers!

You get the air ride in the seat fixed yet?

Where do you find diesel mix fuel for this thing???

Nice brother 😅

Sounds good!!

The best advice ever, from an old-timer Bus Operator: Go Slow, and use your Mirrors.

nice video bro,love from romania

Is there an engine brake on that bus?

Good catch!

Great 😅 nice gmc

Im ready for the longer more extensive video! I bought a 1957 4104 and i am trying to learn how to drive it. I'm going in blind here. Ive taken a special interest in these buses and have been operating on a "ill figure it out later" mindset But now its later and i need help 🙃 Im an on hands/ visual learner and your videos are the only ones ive found on how to operate these things. Any resources you learned from are greatly appreciated

I was born in 1959 Argentina. I remembered to see some bus on the road.

Tell me about that sailboat please ;)

I just found the video and thank you for sharing this. As someone who has been blind all my life, I have always enjoyed riding in buses with manual transmission, but driving one seems to be another thing altogether. This video shows me that and explains a few things I have heard over the years, when writing in Coaches with manual transmission in Canada. for example: revving the bus high in order for it to grab a gear when shifting down and I always thought that the bus had done it on its own, whether it was standard or automatic. the other thing for me is the synchronized shifting, versus not synchronized. What exactly does that mean, as I've never thought to ask or had it explained to me properly? Again, thanks for sharing.

All I can say is no no no mate you got it all wrong. It sounds like you have no idea how to drive properly.

That some real progress from the first video smooth and no stress or violence on the gearbox 🥂

After you drive it awhile you will know by sound of engine when to shift.

Interesting that your 1st gear tops out at around 15ish. My car's 1st gear tops out closer to 9 or 10, and my 4th gear tops out by about 45 to 50.

Use your tach when shifting helps a lot. Great coach that and Scenic Cruiser.

Дороги как в России зазазахахаха

Good Job! Good Show!

Bro you can single clutch it Using the throttle n rpms back off throttle a little pill it out of gear then clutch in to put in next gear Wish I could take ya for a ride and show ya it will save the clutch n your left leg

You can single clutch it Use the rpms and let off the throttle a little pull out of gear then clutch in put in next gear

You always double clutch up and down that's how you shift buses and semis 1st gear you want to shift before the governor hits at 15mph so shift it at 13 14 2nd gear goes from 15 to around 30 3rd gear 35 to 40 4th gear 40 to 55 if you don't want to double clutch shift like the Greyhound driver's were taught clutch once put in neutral Rev the engine not scream it wait for the rpms to drop some then shift it and you want to use the brakes and transmission at the same time for a smooth stop and remember the passenger's are in the back listening to then engine if you want to learn how to properly double clutch it's easy push the clutch to the floor shift from 1st to neutral come off the clutch all the way push the clutch all the way in when then rpms starts to drop with the clutch to the floor the go to the next gear you have to listen to the engine when shifting in reverse the coach has to be at a complete stop flip the solenoid switch to reverse hold the switch until you put it in reverse

So cool seeing and riding along this bus! Great explanation re: the non-synchro transmission and details when shifting. I recall seeing the school bus driver double clutch a GMC school bus, a 1964 or so. I respect the skill needed to drive this!

double clutch

I’ve ridden many a mile on both Greyhound and Trailways 4104s in the 50s and 60s.

If it’s a 6-71 there are millions of them.

😂 good carr

Nice job!! My 4104 has an air throttle so it's a little delayed on the shifts. Thanks!

Cannonball or Crackerbox, which one of these trucks u were driven?

Former Greyhpund Driver here. You will see a color code on your speedometer. You shift at each change of color at max rev. Should be at 20 to 2nd, 30 to 3rd, and 50 to 4th. Just double clutch counting one one thousand, two one thousand. Down shifts are at same speeds down shifting with max RPM with throtle on the double clutch. Bye the way get rid of the air seat. You don't need it.

I would think you need your air brake ticket

i know this is an old vid n ya probably got the timing down,but the easiest way. to get shifting smoothly is only push the clutch down about 2 inches when double clutching and shift immediately.the pause in neutral is very breif.your to slow gettin into the next gear .shift b4 the engine hits the governor.stay away from sliding gears till your timing is perfect,the short clutch pedal action will get that there but done incorrectly the damage will likely be permanent.

What’s your plans 4 this coach?

Whoever taught this guy is a complete failure

Very pretty bus I really enjoyed watching your video love the sound of the motor

You can just float those gears without the clutch.

WHAT is wrong with your seat?

Here is a Tip for You to Help in Shifting. Theory is "Engine RPM's Verses Road Speed"

It looks to me like you are not "double" clutching correctly. You might just not be saying it but when double clutching you depress the clutch to pull out of a gear and release the clutch in neutral. This brings the trans to engine speed, then depress the clutch to pull into the next higher gear. That's the way its done.

Nonsynchro transmissions are not that hard to shift. And you don't really need to rev the engine that much nor that long on the downshift. It takes time, but you can develop a rhythm. Also, until you learn to listen to the engine speed, use the tachometer.

I remember when these buses were everywhere on interstate highways in the New York Tri-state Area. What a great vehicle to own. 👍

I like old vintage GM bus Detroit Diesel 6-71 6 cylinder
