Okay, getting all the bugs worked out on a fresh 440/727 we just installed in a 69 GTX (thanks for everyones help. This thing burns some serious rubber  ). What causes the flare up at the 1-2 shift? Band adjustment? 2nd to 3rd shift is nice and solid. Oh, and the kick down isn't working either. Has a Lokar cable on it. Thanks!
First, it isn't a kick down , it is a throttle pressure valve.
It tells the trans what power it is going to get!!
You are over powering it and slipping the front band. There should be no flair up on the 1-2 shift. If the band is adjusted wrong it can flair on the 2-3 shift.
Exactly , 1-2 shift is just the band applying and stopping the drum , till the drum stops you are in FIRST gear, if you are seeing the rpm jump then the rear clutch is slipping, which is not a good thing either.
