lentech automatics

[redrider]

I have an 88GT with 550 crank horsepower. I bought a lentech street terminator plus about 4 months ago and now I'm sending it back for a new one. I started to pass a car at about 50 when all of a sudden the engine revved wildly. After that I limped home barely able to make the car move. The tranny is rated to 700 horsepower. I have long tubbe headers that make contact with the pan and wondered if the heat may have broken down the fluid. There is another weird occurence I have experienced with the former aod also. When I slow down for a light at about 20 I get a forcefull drop in speed which seems to come from the rear end. I have a true trak diff with 4.10 gears and the mechanic that reinstalled the moser axles had to grind them down because the diff made them too long. He did have a tough time fitting the right side axle in and I wonder if that could be causing the bind that I get when slowing down. Also this sudden drop in speed may affect the tranny indirectly.

Please help me out with ideas for a fix.
Thanks
