3.0r front and rear diff problem

Postby Jmcguire » Wed Aug 31, 2016 9:46 pm

Hello everyone,

So I have a few questions, I have a 06 Tribeca 3.0. I had usdm motor in it til, I had a really bad rod knock, so I bought a JDM transmisson and motor. Everything switched over fine and smoothly. Except one thing... The transmisson, that was all fine expect shifting, in second gear it seems to shutter and then from 3rd to 4th it wouldn't shift til it was at about 4K RPM's. So correct me if I'm wrong, the gear ratios are different from the JDM front diff to the USDM rear diff. So my ultimate question is, is there anywhere I can get a JDM rear diff that'll fit my 06 Tribeca 3.0? If I can't then if anyone who's if I should swap from the USDM front differential to JDM transmisson? Thank so much!!
