Ok well last night I finally made it to the track. Ran some good times considering the carb is out of the box. Ran 12.64 @ 108.66MPH and 12.08 @ 114.7MPH with 100 shot. Unfortunately as I was racing, my RPMS were going high (close to 7000) but my car would not shift (towards the end of the track). When I left the track it was not until about 5-6000RPM that the car shifted out of 1st into second gear. I am assuming this is my tranny and not stall. Any suggestions? Where can I get a new one to handle over 900 HP and high torque. This was a stock 700R4 and my motor is in the sig. Thanks in advance.

 

If you lost the ability to shift out of 2nd gear until WOT, and this happened all at once, then the governor gear (stripped, broken)could cause this. If you are looking for a 700R4 that is going to handle 900 horsepower, it's not going to happen (it does not exist).

 

What do you recommend I do? I have 4.11 gears in the rear. I drive highways too. Also I have a new converter made for the 700R4 that cost me $500. Kinda stuck here... any suggestions?
