I am looking at buying a k20 here locally and when we went to test drive it, I noticed it seemed to clunk pretty bad when you shift from park to drive or reverse to drive, pretty much all the gears. It has a rebulit 350 and th400 in the last 12k miles. Any ideas, is this a big deal? Also what is the proper name of the cover that covers the torgue converter and flywheel, it is missing is that a problem?

it could be the ujoints. one of my friends truck does that and he says its the spider gears /forums/images/graemlins/dunno.gif
i run my truck with outthat dust shield, only problem i have found is mud gets in there easier and kills the starter.

I believe you are referring to the inspection plate, as far as it being a big deal I have not run one in ohh about 7 years but I have a SM465 and have found nothing wrong with that now Im sure someone will say different but just telling you I've gotten away with out mine for sometime. I noticed a similiar noise in mine while I was manually shifting the gear while operating the vehicle and it came to be that my body mounts were sooo shot that when I shifted the body would clunk against the frame. Just an idea for you to look into. Good Luck...

Sounds like u joints or excessive backlash to me.

check your u-joints. make sure when you check them you block the tires and have the tranny in neutral so the driveline is not bound up
