I have a 96 Toyota Camry LE Auto 4cyl. Has a big problem upshifting. Now it shutters real bad going uphill, and the rpms go to 4 and 5k. I back off and slow down, soon having to pull over and stop.
Once i shut if off and start it again it drives 50mph til the rpms start going high again. I stop and repeat. Do i need a new tranny or could it be the shifting selenoid or sensors?
