I personally have had 2 auto's and 1 manual r154, never broke anything on any of the trannies and I don't go that easy on em, I do a lot of drifting, the most I have done is run out the clutch. Supra trannies are very robust, usually only break due to driver error or over abuse of HP IE 450+HP can do some work but even then I have seen a stock R154 last several years on a 550HP application. If its the tranny it will most likely throw a code, is the check engine light on?
