Tranny Noise

[cleszkie]

I run a 350/350TH combo in my 72 K5. When I shift the auto tranny into reverse, there is a slight "klunk" when the thing is engaging (there is no noise when shifting into any of the forward drive settings). What is this, and how worried should I be? Just had the thing rebuilt less than a year ago and is still under warrantee. Any opinions, experience with this problem, possible remedies, or condolances are appreciated!

Are you sure it’s coming from the trans? I'm sure you'd know if it was u-joints… but it could also be that the driveshaft is worn out. I used to get a clunk when I'd start from a dead stop that I traced to the driveshaft. If I lubed up the slip joint the clunk would go away for a short while.

Check the u joints and also the rear end. If the rear ens has alot of play it will do that. I just found out why the burb clunked when I put it in reverse, it was the side gears are chipped and clunked till it got to a good point. I wouldnt really do it in drive though go figure.
