Need T/C for 4x4 swap behind an nv3550

[gaucho919]

Hi gents, I'm currently looking for a transfer case for my '92 MJ. I have a couple junkyards around with XJ's from 87-99. What year T/C would work better? as far as speedo compatibility? Thank you

[Sir Sam]

91-01 XJ, granted that you remove the electronic sender and install the mechanical sender. other years of ZJ should work as well, but I am less knowledgeable on those.

My sender from the 2wd ax-15 has an electrical plug on it, making it and electronic sender right? would the xj sender plug right in?

I believe either 1996 or 1997 was the first year for the newer style of sender plug, so you would need a sender from an older XJ.

your 92 should have a 231 i m pretty sure. that should bolt behind you (envy)3550 lol . and the spedo sender should be easly removed via the 1 7/16 bolt

I should've been more descriptive, my '92 was factory 2wd. I'm doing a ground up rebuild on it, using a '97 motor, '01 intake, and 04 nv3550. I got everything except for the tcase right now.

[jeepers]

ok i see now,,lol a cherokee of your same or later year should hook you up . stay away from the yj t cases as there is a clocking issue. been there done that ,now i have an ax15 .

[Sir Sam]

Is the 04 NV3550 from a TJ or KJ? If its from a TJ it will be clocked differently, than the KJ or XJ units are.

[gaucho919]

It is from a TJ.

[gaucho919]

Where is this clocking difference located? in the t-case or transmission?

Transmission, either you need to redrill the mounting holes to rotate the transfer case down some, or you will need to "modify" your floorboard with a hammer.

 

I hammered the hell out of my floor to get it to clear.

[gaucho919]

looks like I'm gonna need a big hammer then,

Sir Sam- what transmission mount did you use? will the stock one work?

The mount is the same between the AX15 and the NV3550 XJ's, but there is a plate that bolts to the bottom of the transmission and that then bolts to the tranny mount, that is different than the ax15 plate, either make your own or consider buying that part new from Jeep.

 

I did not use that part in my application because with my engine swap my tranny sits back ~4" from where it is supposed to be.
