Transmission
All transmissions, clutches, pressure plates, and flywheels are interchangeable.
Gears swapping can be done using the gear sets. LSDs are not swappable as the belt housings are different.

NOTE: THE BEST TRANSMISSION FOR YOU F22 and F23s is THE M2S4 or M2B4 ( contains LSD ) H22 transmissions are geared a shy to short for our engine. These have been known to shave .7 off the quarter mile respectively.

What's this I hear about the 1st gen auto trannies being crap?
a. Differential bearing failure- usually indicated by the axle seals leaking
b. 2nd gear clutch pack failure- usually indicated by lack of second gear, excessive slipping in other gears, car redlines before shifting, delayed shifting (car hold current gear way longer than it should).

There are far more issues is you have a 3.0 than a 2.2/2.3, as the transmission just doesn't handle the power output off the V-6

It is also highly recommended that you put a transmission cooler on your car to prolong the life of the trans and at a minimum change the fluid every year or 30K.
