On the 3 to 4 shift having some issues so my question is what clutches are applied during this shift? And if I'm going back into the trans any way to completely solve this issue. I've had one trans build and a refresh and still have the bang into gear driving or flare while WOT. Any suggestion or real fixes? Really tired of putting money into this.
