You asked if a hp90 fits in a car that has a hp45, no? I was aware the housings were different and wouldnt fit. Didnt care to argue with Mike over it

Hence i figure to put a stronger torque converter in it. But i would first wait till something fails then open it. If its the clutch packs it makes no sense changing the torque converter.

We'll see how it holds up. In january my car is end of lease. Maybe i put it stock and sell it. Maybe i keep it. Time will tell.
