Does anyone know if the internal parts of the XJR's 4L80e are identical to the GM version, or are there differences?

I am contemplating rebuilding mine while it's out and before I transplant it into another car and was wondering if a standard GM rebuild kit will work, or if there are major differences. So far it appears that the torque converter and pan/pan gasket are Jaguar specific, but I wasn't aware if anything else was unique.

 

Torque converter; By different do you mean stall speed is Jaguar specific or there is actually something different with the interfaces; flexplate and crankshaft ?

 

What I read was that it is reinforced to cope with the higher max RPM of the Jaguar engines ( V12/ XJR) vs a Chevy engine. Other dimensions, such as diameter, mounting lugs, pilot diameter and shaft splines are identical to the GM applications. Within the GM family of engines, various stall speeds are available depending on the engine and application.
