904 "braking" in 2nd gear
He told me I needed a 727 so i thought maybe he would just tell me that again.Thanks,

Yeah a lot of guys think a 727 is needed for any type of performance car but it really isn't. Especially if your running a light A-body. Their are tons of them running around with a 904 and just a good shift kit like the Trans-go running 12 second 1/4 miles (and faster sometimes) and they are holding up just fine.
I've been thinking a lot about your problem and think that it has to be a valve body issue because if the rear band was applying when it shouldn't be it would mess up 3rd gear also, not just 2nd. Also if the front clutch was applying when it shouldn't be 1st gear wouldn't work right.
The sequence of events for shifting are:
Put it in forward and the rear clutch applies and stays applied throughout all the forward gears.
In 1st gear only the rear clutch is applied unless you have it in manual low then the rear band is also applied.
When it shifts to 2nd the rear clutch stays applied and the front band applies. If manual shifting it the rear band releases and the front band applies simultaneously.
When it shifts to 3rd the front band releases and the front clutch apples simultaneously.
I've seen guys mess up putting shift kits in several times. Seems they can't or don't read the instructions good. It's quite possible that is what happened.
