I was thinking the same thing. Great opportunity to open up the case.

OK, So the good news is I received the Rubicon transfer case. I spoke to my dealer and they were somewhat skeptical of re-flashing the computer. He said they were willing to try if I wanted, they would charge me I think he said $127. He said they have had instances where customers have asked for flashes like this and had a bunch of problems. What scared me was that they said in some instances they were unable to revert back to original programming and the customers had to purchase a new PCM which costs over $1,000.

So my next call was to AEV. Spoke with a very nice and helpful person. I explained what I was trying to do. He said the new version of the Procal would be capable of programming for use of the Rubicon 4:1 low range ratio. He said they should be releasing the new pro cal in two weeks. I find this a safer, less risk option so I have decided to hold off on installing the transfer case until I can get my hands on a new version Procal. More updates to follow...

A guy I wheel with just had the flashing done by the dealer. They charged him $90. He has a 2012 and put in a 2013 Rubi tcase.

I agree with you, I'd rather buy the Procal and flash it myself.

I will still have a issue of the computer not recognizing the "new" low range gear ratio. I have spoke with Advanced Adaptors and AEV about this. Advanced Adaptors said that they have been working with BullyDog on a programmer that can program a change in low range gear ratio. AEV said they are working on it and hope to have it out soon. I plan to call my dealer and see if they are willing to do a re-flash for me. I know it can be done but not sure if they are willing. Since it is a factory option, there's no doubt they have the capability. I'll update this thread again after the swap is complete.
What did your dealer tell you about programming the PCM to recognize the 4:1 ratio? I just installed a 2013 Rubi transfer case into my 2013 JK Sport. I'm experiencing an RPM limitation while in Low 4. I took my JK into the dealership today but the mechanic said he didn't think his factory diagnostic tool could actually program the new ratio.

AEV has the "AG Level" Procals in stock according to a conversation that I had with them on 2/10/14 but they don't have the user documentation yet. Cost will be about $160.

Nothing new to report. As I already mentioned the dealer said they would try but made no guarantees. For what they want to charge I can buy the new AEV ProCal when it comes out. I'll remain patient, spoke to AEV again this morning and still nothing, they won't even hint at when it will release other than to say "soon".

What you are experiencing with the limited RPM in low range is normal until you reflash. Kolby @ LS turnkey in Oceanside, CA told me that if you let it just sit and idle for a minute it would clear itself and operate normally. But, only for that time. The next time you shift out of/ and back into 4 low the same thing would happen. I didn't want to deal with that so I'm waiting on AEV. Good Luck!

That's a bummer, my OLD Rubi will rev to 5K anytime I slapit into 4lo and I've gotta be a little careful of the sudden RPM climbability-

JIMBO is right, with a 4:1 ratio in lo range and esp if you are in 5th or 6th in a manual, it is easy to drive the t-case pinion gears to well over 10,000 rpm if you are not careful...that's spinning pretty fast.

You are correct...I placed my order this morning. With any luck I'll have the swap complete this weekend.

Do it with Superchips Flashcal

Closing the loop. Just purchased the Superchips Flashcal. It took less than 5 min to make the change.

Sorry to dig up older threads, but does anyone know what the input shaft spline count is on a 2012+ automatic rubi transfer case with the external spline input shaft? I'm getting all kinds of conflicting information, 26 spline, 30, 32, etc...anyone know for sure? I can't really seem to tell from counting the splines in the pic on the first page.

I spoke with advanced adaptors on Friday and the guy I spoke with was under the impression it would NOT work. He thought there was a difference between the 6 speed and Auto transmission Tcases. Can anybody confirm this with a high level of certainty?

Thanks, David M

If I understand everything that I've read other places, you need a case from a 12+ AUTO transmission.

07+ Manual's and 07-11 autos can all interchange, but because of the transmission/tcase change in 12+ auto's you must stick with a 12+ auto tcase.

This is correct. I have a friend that just had this done on his 12. It's the same reason you can't get a rubi crawler or 4 speed Atlas (can only get a 2 speed Atlas).

When they did the 12, they made the electronics too complicated so the stuff from '11 and earlier won't work including most of the programmers. AEV just recently updated their Procal so you can program the transfer case swap. Before that it had to be done by the dealer or it would go into limp mode.
