Hello guys,
I am wondering if the 2.5L auto out of a 1997-99 boxster would be a plug and play swap for a 2001 2.7l boxster base model. I have seen things on wikipedia and rennlist that suggest there are alot of cars that use the 5HP19FL transmission, however i am wondering if there is anything additional involved in doing this swap.
ECU re-program, torque converter compatibility, etc. I have heard that the gear ratios in the 2.5 are different, but would this require a ecu re-program? Any info would be appreciated as it is pretty rare to find a 2.7L auto for a good price.
