automatic transmission

My question is I hear a loud clunk when shifting into reverse and was wondering if it is the u joint? The noise comes from the rear but only when shifting into reverse. Sometimes it shifts fine into reverse. I see there is play in u joint when rotating drive shaft back and forth and here the noise when driving. Shifts fine into other gears. My engine is a 351m and a c-6 automatic

try to tighten the yoke up they loosen over time..and if you have play in your u-joint i'd change it...it may take care of your problem

How do you tighten up the yoke ? and how do you take the slip joint off of the rear driveline mine won't come off and the repair book I have doesn't mention it?

you have to find the right sized socket and just tighten them/it up
