yeah i was going to post in the modular forum, but this forum gets 10x more traffic, and the tranny isnt limited to modular cars.
as an added note to this problem, if i drive on the highway for an hour and get the tranny nice and warm, i cant get the problem to happen no matter how hard and fast i shift, what could possible cause this? how could the tranny being real warm make the problem completely go away. is it the fluid? im so busy this weekend im not gonna get to look at the fluid

maybe some day this week.
oh yeah, there is 105k on the car and i have no reason to believe the tranny was ever changed or rebuilt.
