- My 99 Gmc Sierra started going into limp mode transmission wise. the gauges and clusters all remained working and the fuse for ign 0 was intact . so here is a video of what i discovered was causing the issue . as well as a surprise bonus issue that arose from the fix.
You dnt knw how much i appreciate you postin this video you just fixed my problem thank u again
Same here... friggin mice got under the fuse box! Arrrgh!
Thank you, this is great. You should have soldered that broken wire and then melted the shrink wrap on...
when fixing wire's I always solder them together you'll be sure not to have to go back in to fix it. unless a chipmunk comes back.... but remember to use the rt solder thin electric solder of course not plumbing solder.. and remember to always put a little on tip just before you start. good video. bro.
Thank you, this helped me so much. I haven't even done the work yet but now I understand the problem.👍👍👍
Helped me a lot 👍🏽
I have a 99 4 wheel drive GMC 5 3 1/2 ton with 4 l60e transmission it will not go into Ford or reverse at all possible problems
Thank you 🎉
I need help my 1999 Z71 4 x 4 will not shift out of first gear when in automatic when you shift it manually from 1st to 2nd it’s Shifts but it won’t go to third
Just put a new transmission in my 2000 Tahoe it's stuck in 3rd gear will be checking this tomorrow.... hopefully this fixes it....truck set for almost 3 years
Check you transmission harnes I had the same thing and my transmission harness was disconnected
How fast would you be able to go when your truck was in limp mode?
70 if ur lucky and toggle the pedal
I got a 1991 Chevrolet silverado and it will only engage in reverse the gear shifter moves through all gears but reverse is only gear that catches
First dam video that makes fucking sense 👏 👌 thanks my feild driving friend!!!!
I should say that my 2002 GMC YUKON XL IS ONLY DRIVING IN FIRST GEAR AND WONT SHIFT BUT ITS NOT SLIPPING AND THE CODE READS NO CONNECTION TO THE COMPUTER. AUTOZONE SAID THAT I SHOULD BRING IT TO THE DEALER FOR THE COMLUTER ... IM LAUGHING BECAUSE I WAS INTENDING ON RUNNING THE 12V LINE TO THE TRANS .... LMFAO
I just bought a 2003 GMC 1500 Z71 off road for $1500. The guy says that it needs a transmission. I'll look for the pink wire.
Thank you
I have an 1993 Chevy Silverado transmission shifts out good but has to put it in low gear to take off
James Andrews I have '96 GMC 1500 pick up that has that same problem basically. How did you fix yours?
THANK YOU
I have a 1999 5.3 it will only act like it’s in park. When parked it was fine. What could be wrong
The factory would have at least soldered the Damn Thing !!! Good Video Except For The Most Important Simple Step!!!!
I have and 04 GMC Sierra 5.3 was driving one day and what I know Limp mode happen
Were you throwing any codes? I have a 2000 that won't go into 3rd or 4th. I have no codes.
Same here
The way people are talking about the LIMP mode sounds like a ed personal problem for erectile dysfunction.
What does limp mode do does it make it stay in first gear
It forces the trans into 3rd gear
@@lumpasaurus4431 i didnt know that
Mine goes limp mode after a while of driving like when it get hot!
If it's electronic throttle body you probably have a poor connection on one of the pens on the wiring connector. I unplugged mine squirted die electric grease on the female side of the plug and worked it down into the holes. Plugged it up never had a problem since
You ever figure this out?
I’m here to figure out if the problem ever got solved ? I’m having the same problem truck shifts good up until it warms up.
Same here! Brand new from autozone. As soon as it it hits 120degrees I go into limp mode with no codes.
I’m having the same issues . Shifts great when cold when temp gets up to operating temp it loses all gears and engine stalls does not cut off . Help.
Ok think i may be having the same issue not sure .. I recently bought a 99 gmc sierra 5.3 l v8 4x4 with the 4l60 e auto trans .. Check engine light was on when i bought it.. Scanned for codes and itv was throwing a fault code for shift solenoid a , was still shifting at the time tho.. And it's am easy enough fix so bought the truck.. .. About 4 days into driving it.. I hit a pothole and speedo went all crazy then stopoed working seconds later .. All while the trans was trying to figure out what to do.. Now i was able to limp it off the main road and chevk things out .. I couldn't find any major signs of catastrophic failure ... Shifted manually ( column shift) thru every gear and they all work like they should 1 ,2,3 ,r , even d .. But won't auto shift like it should.. So endedv up towing it home asi didn't want to cause damage to it ..
As of now I've changed fuses to brake switch , btsi under hood . couldn't find the vsb (speed buffer) behind glove box .. To try resetting that , nit sure about that anyways , i have replaced both shift solenoids with ac delco parts , new fluid new filter ,, replaced ignition switch.. Csuse i read somewhere that the 12v source that powers the solenoids goes thru that 200 $$ cluster fuck of wires and there were a few big cuts showing bare wires in a few.. Probably due to the steering wheel being lowered .. Idk for sure but replaced that .. Ive read multiple things and with each new thing i read it seems to contradict the previous .. So i guess my first question would be was your s giving you a fault code for solenoids ? And two .. Do you know if the 12v supply to the solenoids is a constant ? Or is it only supplying while running? I still have yet to check for 12v current to it .. But just trying to get a feel of where to go next .. Any input would be appreciated .. Thanks
Dude my buddy had a 98 that did this and his ignition switch turned out to be his issue.....not at all saying thats yours....but can yiu imagine his surprise when he put that brand new transmission in and it STILL didn't work....thought he was gonna shit 😅😅😅

Don’t know which do check first
Mine has R &1rst, Every once in a while- it’ll get high gear. ,,, 4 tahoe
Where’s your flashlight
I’m having the same issue on my blazer imma check under the fuse box tomorrow reply to this comment so I can update if any you all wanna know what I find out about mine. By the way I replaced several solenoids and changed my filter and fluid numerous times as well as the inner harness because I believed it was an electrical problem***** but will check the fuse box connections ASAP.
Did you fixed your truck?
@@Anthony-gw8sx no I am still having this one code, Shift solenoid 3/2 downshift. I’m all out of ideas. When it warms up a bit I’ll drop the pan again and see what I can come up with
You figure it out yet?
@@stevenswiatek6268 A-B solenoids. But I’m still having the code for 3/2 downshift solenoid that could be just a bad ground. I saw another video that explained how the ground going to the computer for that particular solenoid tends to go bad and they used to repair it for free but stopped or give an upgrade kit to replace the bad wire inside of the harness. Also to note***** When reinstalling the transmission pan, be careful not to damage those two A-B solenoids because that was my issue.
@@5thsNGunz so after you changed the downshift solenoid it still threw the code?
Does anyone else ever think that some people make videos on repairs that they make on purpose to make themselves look and feel like a GENIUS. ( example , cut a wire ,make it look like it is old and corroded, or put there own chew marks on it .) I AM NOT AND SAYING THIS IS WHAT THIS PERSON DID . I AM ONLY SAYING THIS BECAUSE IT JUST POPPED IN MY MIND . ESPECIALLY IF PEOPLE ARE GETTING PAID FOR THEIR ADVICE. ( MY BRAIN WORKS IN A MYSTERIOUS WAY, KIND OF SCARY SOMETIMES. ) MAKE sense though, Right
trust me ,y three videos on this channel are not making any money this old truck is a Michigan salt life corroded basket case. what you see is what i was looking for to fix.
Dude buy a flashlight!
And go camping
