had trans built recently. only thing different than last 5 builds is hd2 kit. 2-3 shift has not been right since. my guy followed the install to the t. 1st time back he put original pump regulator spring back in. 2nd time back he pulled the lip seal on drum and did something else (can't remeber). just got it back today with a new brf valve body, and it's worse than ever. i think something smoked on the way home. won't even stay in 2nd now. like i said, only difference was hd2 kit the first time.
