Tractor parts chaser question....

Super Trucker · Nov 28, 2014

I just picked up a 02 GMC 2wd 1/2 ton for a parts chaser.It has trans issues as it will shift up thru 1-2 then when it hits 3rd it starts up and down shifting. Fluid doesn't smell burnt but I find friction material on the stick. I'm pretty sure the trans is smoked but want to see if there is anything I should check out . Oh and no check engine light.

sounds like the clutches in 3-4 are shot. not an uncommon problem in the 4L60-e trans.

First ? is does it have reverse. If not the sun shell broken. It sounds like 3-4 clutch. That is a easy trans to rebuild.

I have all gears . Just it just has a hard time staying in 3 and 4.

this may sound odd but I worked for a place that had a 04 chevy with the same issues and after a new trans and a trip to the dealer they found out it was in the steering colum and the final cost for the colum was below $100. The total cost with a rebuilt trans and man hours almost scrapped the truck though. I also had a 94 that when it started that you would pull over shut off the truck pull out the key put it back in and restart go real easy and let it shift through the gears DO NOT run it hard until it gets into third and dont run it hard enough to cause it to down shift from third to second or you will to start all over again
Hope this Helps
