tranny problems?

98 gp gt / when i come on the gas at take off and spin tires the car jumps {loud hesistate bumpy noise} as if it's not performing correct . a mechanic called it play in the trans. what is this and how much does this cost to fix?

Sounds like your talking bout wheel hop??

Sorry cant help ya, Ive heard of some cars experiencing this at the track, but have never been a victim of it.

I would say that depends on the tire compound and the surface friction factor. I the hop is to hard you should check the tranny mounts.
