So has anyone done any research on replaceing the 1.925 T-case with a 3:1 or a 4:1 t-case?

I talked to the guys at Klune and they said they could adapt a Klune to work. It'd require going to their shop and letting them have your vehicle for a day or two though.

Who is Klune? Where are they? Why do they think they can adapt a Klune to work? Do you have a phone number? Thanks, Steve I talked to the guys at Klune and they said they could adapt a Klune to work. It'd require going to their shop and letting them have your vehicle for a day or two though. |

Who the heck did you talk to CerOf?  I just got a e-mail back from Klune, and this is what they had to say "Sorry, we don't have any adapters for the Mitsubishi's. We typically utilize Dana 300 and NP231 adapters from Advance Adapter and Novak for the transmissions and then design our own t-case adapters. The unit has a 6 bolt circular bolt pattern and the David unit requires 23 or 21 spline output from the transmission. We need the same bolt pattern on the t-case, but we are able to supply a wider variety of output splines, none of which I believe will match your t-case. The Mitsubishi market is not large enough to justify expense and inventory at this time. Wish I had better news. We do appreciate your interest in our product. Thank you for inquiring." So was someone yank'n you chain or what. You got me all excited for nothing.  I talked to the guys at Klune and they said they could adapt a Klune to work. It'd require going to their shop and letting them have your vehicle for a day or two though. |

If you can get the adapters, it can be done.
The transmissions can't be *too* far different from other vehicles. If we can find an adapter to go from the output on the transmission to fit the front of a Klune, and from the Klune to our own transfer cases, it should work.
Might have to custom make one though.
Things I'd want to know also, because swapping transfer cases and bypassing klune altogether would be nice.
1) Are our transfer cases fully mechanical in activation?
2) Do they use a vacuum disconnect for the front axle like on a Chevy or older Jeep Cherokees and Jeep Wranglers (XJ & YJ)?
If they are fully mechanical, then it would be easy to design a cross member to hold a different transfer case or modify the existing one to accept a different transfer case.
Then the issue become of adapting our transmissions to a different style of transfer case. Which could probably be done with a custom adapter.
Of course we are talking $$ either way.
I'd be willing to be our transmissions are used in other vehicles that are maybe, "more common." Again, how many different ways can you go from a transmission to transfer case?
I've never looked at an adapter up close, but it seems like it should have some sort of bolt pattern on each end to match up with the two things you are linking together. Also accept the shaft, etc, from the transmission and transfer case.
Might involve getting a junker tranny and transfer case from a montero sport from the junkyard to play with. Along with a junkyard NP231 out of a Jeep YJ/TJ/XJ to mess with and see how they differ and go from there.
The email I got from them wasn't quite as long and detailed as yours, and I think it was from around a year ago or so. They said they could do it but it would be a custom job. custom job = $$$$$$

Famous last words. Our transmission/transfer case combo is pretty different from everyone else. For the manual transmission configuration built into the transfer case is the transmission shifter and part of the shift mechanism for the 5-speed transmission. A good deal of the rest of the shift mechanism is built into the spacer between the transmission and transfer case. Designing a Klune would mean redesigning that spacer and dealing with the shift mechanism. Something they've repeatedly told us 'NO!' on. CoSport and I have talked to Klune several times regarding the automatic transmission vehicles. They - again - have repeatedly said 'No. They were not touching the Mitsu.' There isn't a big enough market to justify the cost of developement. Better track - figure out which Mitsu t-case that takes the new 2.85 gears will fit you'alls Montero and Montero Sports. The swap would be minor and a LOT cheaper then a Klune. I just completed the 2.85 gear install in a t-case I purchased from a junk yard in VA for $450. Grand total ran me less then $2000 for the t-case, gears, gaskets, etc. A little common sense and basic hand tools are all that's needed to remove, rebuild and install a Mitsu t-case. As for reduction - those that think they need more then 2.85 need to seriously consider whether they have another problem or not. Such as not having changed gear ratios in the axles after putting 33-35" tires on. I run a 5-speed with the effective factory gear ratio at the pavement and after testing the new gears I can't immagine what they would be like with an automatic transmission. 99.99999% of you do NOT need a Klune @ 3+ to 1. And, yes, I can hear it now - OK, it would be nice SOMETIMES to have a 4-1 but NONE of the pics I've seen of any vehicles on this board can make use of a transfer case that geared that low. And, are you all ready to start replacing blown t-cases? Because putting a Klune between your existing transmission and a 1.90 transfer case is not going to make for a happy parts marriage. I'm not trying to be a wet blanket or sound like I'm on a soap box but I think some things are being over looked. Remember people, we don't drive Jeeps. What works for them almost certinly never does for us. Edward --- If you can get the adapters, it can be done. The transmissions can't be *too* far different from other vehicles. If we can find an adapter to go from the output on the transmission to fit the front of a Klune, and from the Klune to our own transfer cases, it should work. ... |

Ahh, did not know that about the transmission and transfer case linkage being all intertwined and co-mingled and what not.
That was some bright engineering on Mitsu's part.
I was seriously considering selling our WJ Grand Cherokee and just modding our Montero Sport, but it would cost way to much to get it where my WJ is right now with just bolt on parts.
Oh well. The list of t-cases the 2.85 gears says it won't work on Auto 3.0s. So that rules me out.
I have found that the 2.72 low range isn't enough on my WJ, granted it only has 3.73 gears (eventually will be 4.56 gears) but still, a crawl ratio in the 50~60:1 range would suit my needs perfectly.
I wonder why the 2.85 gears won't work in the auto 3.0 t-case and how much different it is?
