ok guys here a question for all you gurus...
I'm not sure but if I replace my KL03 with a KLZE do I need to do anything with the tranny???
No, your stock one will be fine.
However, while it's out of the car, take the time to clean the case, check the various seals etc and change the oil.
If it's an MTX, take the opportunity to get a new clutch and consider having the flywheel lightened while it's out.
If it's an ATX, take the two pans off it to replace the gaskets & oil strainer and clean out any accumulated metallic goop.
