Need to rebuilt or replace transmission in Austin, Texas

Hi there MCers,

My mechanic tell me I need to replace or rebuild my transmission. It is leaking transmission fluid (it's in the hull). He said the transmission is cracked, I think. Does anyone have someone in Austin they recommend to do the job for a reasonable amount? How much should I expect to pay? Or in the alternative, do you know of a place I could ship it to to have it done?

Thanks!
