Thread: GM 5L40E transmission Re-built to 5L50E specs

Yeah, fair enough, that makes sense. I generally keep my cars until they are ready for the scrap heap. Last car I bought before this was a VN commodore that was 4 years old. Only just sold it for parts after 18 years and 400kkm.

What about importing a rear drive Cadillac engine and trans and wiring, computers, etc.to go into your RR? The Northstar V8 is rated at 292 hp, and the 2011 V6 at 302 hp. The V6 uses a 6L90 transmission. Some Cadillacs are 4wd so there may be a transfer case attached or the ability to attach a LT230.

I think it is just a matter of time before someone has a crack, as more and more of these vehicles are getting to the point where thier trannies will fail. Once I am back on the road, I should have a few years to think about this, but as I plan to keep mine a long time, maybe By the next time mine fails, someone will have come up with something.

What are the dimesions of the ZF, and are the transfer cases the same on the V8's?

I can't see why it couldn't be done....

Hi Gav, can you please email me tonight about your transmission rebuild I am planning on going from home (batemans bay) to Sydney to see Furious Performance about my transmission thanks Roger.
