I know this subject has been covered before....was just reading some old posts.
This is what I got a 95 YJ stock from 2.5 on back.
Have complete 4.0 to go in.
Guess what I want to know is what all is needing replaced what is all the little this I'll need to gather up before I tear into this project...so I'll have everything on hand I'll be needing during swap.
Any feed back would be greatly appreciated.
yup.. they tranny too.. thats a good thing because the 2.5 tranny isnt as robust as the 4.0 tranny. you'll also need the transfer case from the 4.0 because the 6 cylinders have a larger spline count on the input shaft (also stronger) [img]images/graemlins/RockOn.gif[/img]
Yes like it has been said, this project is not nearly as easy as you might expect. The 2.5L uses an AX-5 trans and a NP231 with a 21 spline input.
The 4.0 uses an AX-15 trans and a NP 231 with a 23 spline input.
SO the easies way to do it would be get all three pieces and swap them in. But you can get a new input for the transfer case from Novak for $90, probably a lot easier than trying to find a Tcses. But you are going to need the 4.0 and the trannie.
you're also gonna need the fuel pump and lines, the computer for the 4.0, the underhood harness from the bulkhead connector, the 4.0 radiator, plus the other items as mentioned. [img]images/graemlins/givemebeer.gif[/img]
the easiest way is sell the 4.0 you have and search for a wrecked yj complete with a 4.0 and start swapping everthing engine, tranny, transfer case, and wiring harness headlight to taillights. I have actually done this swap on a cherokee trust me its no easy undertaking.
Hey guys THANKS for the info.
Like I say have complete motor... com.,radiator everything.
I have a 5 speed tranny now (how do I identify my tranny?)
Also I have a 84 wagoneer with the 2.6 is there anything out of that I could use? it also has a 5 speed.
Also how do you identify the axles it has? I can only find the gear ratio.
Any info would be great. Thanks
if you go to www.offroad.com/jeep, somewhere in there you can find a section on cherokees and waggys that should have axle and tranny ID info
the 5 speed behind YJ 4 cylinders was either the peugot [img]images/graemlins/puke.gif[/img] or the ax-5, [img]images/graemlins/puke.gif[/img] both of which you wont want (nor will they work) behind the 4.0L.
look at www.car-parts.com and look for a tranny in your area thats from a laters jeep with a 6 cyl,
axles can also be ID'd form the tech sections listed above.
