It is either A) Control arms hitting the exhaust or B) Something in the rearend is messed up. Mine used to do it also, but my exhaust piping was binding on the control arms; after doing dumps it stopped.

could just be slapping the rearend onto the pinion snubber bumpstop above the diff, mine does that on hard 1-2 shifts, I need to trim the bumpstop a bit because of how much I lowered it.

have you messed with the suspension any, ive rebuilt my entire suspension and mine does it, but when my car does it feels like the car is just loading back up after i take my foot off the gas to shift, mine only does it when im shifting hard and fast, I ehink its just the suspension locking up each time as I get traction??? anyone know

My car did the exact same thing.
It's the trans mount. I replaced with a Energy Suspension piece.
