JWT TCU problem. Please help.

[jackjones]

I have a '92 Q and I just had a JWT TCU intalled a little over a week ago. The only problem I have with it is that the first to second gear shift gets progessively rougher as the engine approaches 3500 rpm in first gear. I mean between 3000 and 3500 rpm in first gear, the car literally feels like its going to jump out of its skin, because it shifts so hard and so rough into second gear. This only happens in first gear. But after 3500 rpm in first gear, the transmission shifts as smooth as butter. This is becoming a real pain in the arse, especially in stop and go traffic. I'm getting tired of looking at the tach all the time, and the last thing I want to do is damage my transmission. Maybe I need to get the JWT ECU, as well, I really don't know. Any suggestions would be appreciated.

I ended up putting in a factory 93 TCU in my 92Q for getting the first gear start - unless I accelerate, the shift from 1st to 2nd is way much earlier than reaching the 3500 RPM range - and the shift is quite smooth. However, if I try to be agressive in 1st gear, the shift point is raised upto around 3K rpm and the shift is noticeably harder.
