    Transmission bolt patterns

    Can any one tell me the difference in the bolt pattern to the motor between the NAG1 and the 45RFE transmission??? After all the pictures online I've looked, they look to be the exact same. And I've got a wild idea up my sleeve

    Id imagine they are identical since the NAG1 is used on the Grand Cherokee SRT8 motor.

    OK here is my idea. Some Liberty's have the 3.7 V6 and the 45RFE transmission (not sure what years). Welll, the difference in the bolt pattern on the back of the LIberty 3.7 does not look any different than my 3.7 in my WK. (Besides, why would a manufacture produce 2 different 3.7's??? THat doesn't make any sense)

    Anyway, What I'd like to do is to find a transmission and tcase out of a Liberty, along with the Liberty computer, and bolt it in my WK. I'd have low range and I could install my 3.73 gears. (because the LIberty came with them form the factory on the LImited I think)

    Thoughts? (besides the money factor. this would be a loooong project if it even happens).

    Flame away.

    Well I could do that. But I like to be different.

    Well cool then, You should do something really extreme and switch in a Rubicon Tcase with 4:1 ratio. That would be pretty cool man.

    What I was wanting to do is to put in an Atlas II t-case. I've seen in a few forums where liberty owners had an Atlas II mated to the 45RFE transmission. I think that would be baller!

    Why not just get a transmission and tcase from a Grand Cherokee or Commander so you dont have to mess with computer related stuff. That would be a pain if you ask me and wouldnt be worth it. Some 3.7 liter Commanders come with 4 low and a member on the other forum has already done the swap
