I need help on this one bad: My buddy has a BOT 2004R tranny (only a 2000 miles on it). We've had problems with it from the start, but the folks at BOT have been very patient with us, trying to walk us through repairs to get it working properly. They've also sent us quite a few parts to do it, as we live in Germany. It's simply too expensive to send the trany back to California.
Right now the trany will shift normally when it is cold. Once it is fully warmed up you can't give it more than about 1/4 throttle, otherwise the pressure will get stuck high (we have a guage attatched at the pressure port on the trany, supplied by BOT). This causes very late and harsh shifting. This condition will persist until the the car has been shut off for an hour or more. On restarting the car will shift normally, until it warms up and you give it more than 1/4 throttle.
BOT recently sent us a replacement valve body, which we installed carefully, following instructions in the manual and using a torque wrench (my friend is a licenced mechanic). BOT does not have any idea what could cause this, and neither do we. ANY HELP MUCH APPRECIATED!!!!!!!!!
