Trans clunking a bit

At least that's what I think it is. Stock 2007 Yukon with I'm assuming the 4l60e trans. When I'm coming to a stop and stab the brakes a bit when almost completely stopped, or when stopping quickly, it's almost like something is "catching up" with the rest of the truck. Feels like I'm towing something and the weight catches up on the hitch for those of you that tow. It's not all of the time, but it has happened quite a bit in the last week or so since I've owned it. Curious if this is normal for these trucks. Again, this is happening when I'm almost stopped. Like 5mph and slower.

What year model is it? Common issue is the slip yoke on the driveline binds up and finally "catches up" almost feels like getting bumped in the ass at a stop sign I think there was a TSB on it the grease dries out someone put a grease zert in mine and I keep it greased up and no more clunk there should be plenty of info out there on this

yup i had the same problem also.. remove the driveshaft grease the slip yoke & that did the trick.

Awesome info. Thanks guys.
