hard clunk in reverse??

oldvart

thanks for the quick reply. jacking the car up is a good idea and i will try that. the fluid and filter is all new and the u-joints as well. im leaning towards rearend myself on which one is the culprit. i also did not know about putting the car in neutral on these trannys for the tourque converter to fill. it would seem it would do it in the forward gears as well though if that was the case?? ill find out. well thanks again. bill.
