My car has 650+ rwhp with rxt, stock fluid and ive never had one issue with my mt-82. My spider gears exploded in my diff and the housing cracked, ring and pinion went too launching the car on slicks at 5500rpm. Tranny still going strong. I think most it is how people shift these cars not fully engaging the clutch ect. The rxt grabs hard and the tranny is still holding strong. To break 3 different mt-82's is either really bad luck or theres a major driver error. I don't powershift my either thats asking for it to break.
