Hello all
I have noticed that my transmission has started to go the way of the dinosaurs.
i had my tranny flushed/filter synthetic fluid...the whole nine yards, but i think it'* been to the stoplight nationals once too many. So i have seriously been considering a tranny swap. My question to you is will a SSEI tranny work in a SLE. It would probably be coming from INTENSE..so i would not have a problem with quality,but making the PCM work with another tranny is a whole new ballgame. Any idea'* or thought'*

thanx

I believe the gearing is different. The SSEi'* HD transmission also has a larger differential and requires a different axle.

the SLE gearing is 3.05 and the SSEi is the 2.93, while it dosnet seem as its too much of a difference ther ealre alot of hard parts that are different.

i would just keep the current trans and rebuild with new hard parts, and possibly a shiftkit

there are also 3 tranny codes to need to match with 00 trannies, CHB, FHB, FCB

Other than the gearing and the differetial (and diff cover) the insides are the same between the two (year for year)
