Sounds like a busted transmission mount. One of the easier, cheaper transmission problems to fix.

Mine did the same thing. It only did it when it shifted really hard or when I jumped on it at slow speed. I thought the tranny was toast but it was just the mount.

I agree that it's probably the mount. One word of wisdom though -- if you are generating any kind of torque, or if you drive hard you'll be replacing the stock type mount all too often. So don't just go buy a stock replacement, spend the extra $5-10 on a polyurethane mount. I must have went through at least 2-3 stock replacements in a summer, but I've been cruising for a year now on the polyurethane one. I got mine from summit, I think it's a Prothane brand.

The colors are just for decoration (for those who admire their trans mount daily)
Both the energy and prothane brands are interlocked so they can't seperate. I'm sure you'll rip the treads out of the trans case before breaking these mounts.
