ba10/5 to nv3550 conversion

[thejim42]

I have been slowly but surely trying to make a list of all the parts i need for my 4x4 swap in my 88 mj. ive decided to go with the nv3550 trans over the ax15 and I'm curious if anyone has done this swap and what all needs to be changed since its a newer trans. any help would be greatly appreciated!

Have done it and its Identical to the AX15 but has better internals I believe the changes were for fuel mileage...

 

However you will have to re-drill the t-case mount at the transmission otherwise the t-case will not be clocked correctly or you can do what I did because the customer didn't want me to drill the trans/t-case mount and drop the t-case with I think it was a 1" spacer...

I'm considering doing this myself , I already have an ax15 but found a good deal on a nv3550 .

re-drill where the trans and t-case mate? is that so it doesnt hit the floorboard of the truck? 

[Jeepman]

Yes or drop the cross member to aid in the clearance...

 

 

I think If I were to switch to another manual trans I would go 6 speed which is a tight fit and not quite a direct swap in...
