I now have a billet input shaft in my transmission, as I broke the stock one 2 weeks ago. (should have put in billet to start with) transmission is all fresh again, but I can't get my 2-3 shift at WOT. It started doing this a couple of months before breaking, in fact, the shaft broke on 2-3 shift as I lifted from the floor. transmission shop sent me to dealer to do reflash TSB 18-003-06, which I did, but still same, no 2-3 shift at WOT, it just keeps reving til I lift. Anybody have same issue or ideas on a fix?
