What up HT! I bought a 94 LS Sedan automatic about a month ago. I'm not driving it everday. Still a couple things I gotta do 1st. But I notice when I turn it on for the 1st in the day let it warm up and put it in reverse there's a clunk noise and jerk when it goes in gear. While driving it also has a slight jerk when changing gears.
What do u guys think? Would it be the tranny or possibly the tranny mount?

 

imo it sounds like the mount take a quick make sure the mount is in good condition or even if the mounted is mounted to the tranny. from what u r describing it sounds like it needs 2 be replaced. that would be the 1st thing i check n it wont cause u n e thing 2 look either.
