Clunk at low speeds when semi cold?


Recommended Posts

Posted

I have a 2019 Silverado and after warming up for 10 mins, the truck clunks pretty hard from 1st to 2nd gear. Anyone else have this issue? Trans temp was around 78-80 this morning when it happened.

Happens to me all the time. Seems like a normal occurance on these trucks

Welcome to gm trucks. :)

 

Gm's have clunk while shifting for decades and look to i guess continue the trend with the newer model. Every gm truck i have driven clunks, my 89 s10, my 95 s10 zr2, my 05 silverado and my 14 sierra. I think it's just  byproduct of older leaf spring technology.

It is a byproduct of slop in the driveline. Splines a big contributor. (HINT) Heavy grease. Mines a quite as a church mouse.

Yes the slip yoke has been a constant topic for decades now but i have seen video showing how axle wrap also contributes to a clunk noise. Regardless good luck trying to get a dealer to lube the slip yoke, hell most dealers only have maybe at best a handful of techs on hand that even know what that is today!
