my 2004 yukon “slips” when starting off the line.
when hot or cold, if I come to a stop and then press the gas, my engine stalls, transmission slips and my traction control message comes on.
If I let off the gas and then press again, it is fine. I took to Amco, ugh, and spent $3k on a rebuilt trans and torque converter, but the problem was still there.
I took it to GMC and they suspected a loose ground (I liked that diagnosis) and after working on it, it’s slightly different, but the problem is still there?
thinking a ground or bad module might be the culprit, but how would that explain the “let off gas and reapply” and it goes away issue?
I’ve spent $4k and it’s worse than ever!!
slippin Pete
What do your back tires look like? If they’re borderline, they can slip enough to cause the traction control to engage. The effect can be exacerbated if the two tires are worn differently.
Thanks for the idea, they are OK, but need to be replaced soon, but even if I slowly take off it “slips”… and if i then let off and “stomp” on it, everything is fine?
I used to think the engine was revving, but I’ve tried to watch the tach and it seems and if the whole this just “hesitates” and makes some noise…
but again, release the gas peddle and it works okay then. Also seems to happen on left turns more than others?
I will try new tired this week, but think it might be sumthin else?
new tires, they are nice, but no fix to the problem…
I did watch the revs go up yesterday, so am still thinking tranny or???
but after new tires/tranny/torque converter and cleaned up grounds, and $5000, I need some cheap ideas??
Help, I need click and clack
Your posts are somewhat confusing. You say the engine stalls, then that the engine revs. Which is it? If it’s a hestitaion, start by looking at engine problems (misfiring, etc.) rather than the transmission.
I have a bad feeling that you didn’t need a transmission rebuild. Most of us here advise people to avoid AAMCO like the plague, myself included.
