General Information:

Transmission/Transfer case/Driveshaft Information below. If you see anything outdated, inaccurate, or missing please contact me & let me know!

Transmission Information:

48re vs 68rfe vs G56 Transmission Length:
48re = 26.5in long
68rfe = 27in long
G56 = 29 1/4in long

48re vs 68rfe vs G56 Transmission adapter plate:
G56 adapter plate is 6cm wide.
48re adapter plate is 6cm wide.
68rfe is almost 7cm wide. *You WILL need g56 or 48re adaptor plate!!*

07.5-12 68rfe adapter plate will *NOT* work. I was told that 13+ will work. I have not confirmed this to be true! Use at your own risk.

PRO TIP for 07.5+
The automatic(68rfe) adapter plate on 07.5+ had support brackets connecting to the sides and back of the motor. The bracket to the top of the motor makes installing the transmission a bit of a pain, pull off the bracket before trying to install the transmission.

48RE vs 68rfe vs G56 Transmission Crossmember:
The 48re/68rfe crossmember & trans mount is the same.
The G56 crossmember is the same as 48re/68rfe. *However, the transmission support bracket is different!! You will need a new trans mount (Not crossmember)

Transfer Case Information:

48RE vs 68rfe vs G56 output shaft size:
2007.5 6.7l np273 T-case NPG Part Number 51169: 29 Spline
