I have a question about 700R4 trannies. I have a gta trans am pushing about 600HP and 550LB/TQ. I got a couple prices for rebuilds. One reputable builder said that he could rebuild mine with all new parts. He said he would use the best parts available on the market now but could not give me an estimate of what it can handle. It would also include a transgo shift kit. Cost is 1000 plus my core.

Another price I got was 1700 and the guy said it would handle 7-800HP and 7-800LB/TQ. This was with using all Art Carr products and needing my core.

The last two options are the street/strip 700R4 700R4 or
"limited" street/strip 700R4 for 1625 (plus shipping)
"limited" 700R4 from probuilt transmissions. I want to keep teh 700R4 due to my 500 stall converter and taht I drive highways with 4.11s. Thanks in Advance!
