Mitsubishi Pajero Auto Swap. Failed V5A51 Jatco to V5AWF Aisin. Generation 4 Pajero Montero Shogun 

Appreciate your comments. Thank you

I haven’t replaced a rear seal yet. Once the gearbox is out of the way, it does look straight forward

@gfour21 hi do you mind letting me know from where you downloaded the service manuals? Thanks

many thanks.

Thanks Peter, they are well built but the NS model is a bit rough around the edges compared to the later models. I had an outlander with a CVT, similar experience! Next video will be the engine swap from an NX - stay tuned :)

Best upgrade you’ll ever do. I’ve even done the engine as well. Happy to share what i can to help

Hello, can this same conversion be done with a 4M40 engine?

Cheers mate. How many k’s on your Challenger? I was expecting at least 300km+ for mine but I’m not sure dyno tuning my Paj helped the Jatco’s lifespan I have the lockup-mate :) Marshall was very helpful and made a custom version of the software to work with my new setup (NS engine ECU / NT transmission ECU)

Just turned 200k and about to set off on a lap. I'm fairly particular about servicing the g/b I do it myself and have done roughly 4 full flushes and the rest have been just the pan and filter 9 in total.......anal, but it seems to be paying off. hope all goes well the the new box on yours, its not a cheap exercise either rebuilding or replacing.

@@grants2815jealous as about the lap - I’m sure it tows great. You are right about the servicing. We have a good dealer here locally and mine was done every 45k on the dot there along with coolant + brake fluid flush every 2 years and I never had any issues

Thanks mate! The wiring is very straight forward - as long as you get the loom that goes up into the dash + the 4WD transfer ECU (and for simplicity, grab the ASC/TC ECU and transmission ECU from the donor car) When you get the transmission ECU, make sure to get the plugs from it and about 10cm of the wiring harness. Here is what I did: I ran 12 extra wires to the transmission ECU from the transmission harness via a 12 pin Deutsch connector, using: 7 core trailer wire; 4 core shielded wire with earth wire (for the input/output shaft speed sensors.. stepper motor cable works well) There was a single wire I ran from the old 4WD transfer ECU wiring on the DASH side (pin 8 on connector D228, a 14 pin connector), which is the OBD pin 1 wire, and connected to the transmission ECU Move pin 2 on connector D227 (10 pin connector), on the TRANSMISSION side of the loom, move to the empty pin 3 on connector D228 (TRANSMISSION side of the loom) - this powers the 4WD transfer ECU Cut / remove pin 10 on connector D225 (the large, 39 pin connector), on the TRANSMISSION side of the loom And some twisted pair to connect the 4WD transfer ECU on to the canbus (splice on to the ASC/TC canbus wires - as those wires are the main bus line) All the wiring diagrams are here faq.out-club.ru/download/pajero_iv/maintenance/Service_Manual_2008_2013/2008_eur/index_M1.htm you can’t go wrong if you test all the wires back to the gearbox. The exhaust is a full system “king brown” from pacemaker I had laying there for years but I didn’t get around to fitting it because my auxiliary fuel tank is in the way at the back of the car. There are other manufacturers as well that may be able to make something that suits your car. Hope this helps your project

Thanks mate. Does this link help? What is your project? faq.out-club.ru/download/pajero_iv/maintenance/Service_Manual_2008_2013/2008_eur/23/html/M223010100020600ENG.HTM

Wait till you see the engine swap video…

From memory, the auto in the petrol version has the control built into the engine ecu.. anything is possible but you may need aftermarket controllers to make it all work.

I don’t know the answer. If it physically fits then your only challenge are the electrics - the transmission ecu might not play well in the NM but you could get an aftermarket controller for the v5awf (aisin a750f)

Thanks mate, what pajero do you have?

@@TravelingBanker 2011 NT with plenty of mods. Rev head at heart. Lol

@@pvcs1754 I know what you mean - how did I go from reading Street Machine mags to this lol.. what’s your next big mod? I’m tossing up between a front mount intercooler or a valve body upgrade

@@TravelingBanker I have the Jonny TIG intercooler, which I feel is one of my best mods so far. Next planned mod is water/meth injection. I don't want to have to back out of the throttle towing a heavy van up big hills anymore to control EGT's.

@@pvcs1754 I have the same problem when towing the camper trailer. Depending on the gear I’m in I’m choosing between high IA or high EGT. Have been looking at the Jonny tig IC (everytime I look at it the price goes up 😂).. any tips on the install? Maybe the water-meth injection is the next mod 🤔

Gday, I’m using the Mitsubishi diagnostic, “MUT3” and the companion software on a windows laptop. What happened to your box? And what are the symptoms?

@TravelingBanker is it possible to buy this MUT3 device? After a full forward flush using about 15L of Penrith ATF LV for my Aisin, it's not shifting past 3rd, TC feels like it's slipping a lot and doesn't lock up in gear even with Auto Mate. Is there a way to DM you about this?

@@johnsmith-ek8mf a quick google will bring up your MUT3 options. How did the water get in? And have you taken the sump off the transmission to inspect? Your issue does sound mechanical and I suggest you seek out a reputable transmission specialist to help you diagnose the repair. There’s a link to my instagram page in the About tab - open to connect with you there.

Thanks mate. I’m using the MUT VCI hardware. I had to set the software to a 2009+ model so it would connect correctly with the transmission and transfer ECUs.. it didn’t seem to affect connection to the engine ECU

@@TravelingBanker Thanks for the confirmation. I was kind of hoping you were able to use a 3rd party interface with CAN Pass-thru :D

Cheers mate.. wait till you see what happened a year later to the engine :O

Really good question and it is one I asked myself. If you weigh up the cost of a reconditioned Jatco VS what I outlaid for the swap, it worked out a similar cost.. and why would you want a second hand transmission from a different model when you could have a reconditioned replacement for the same price and less hassle? Firstly, the Aisin is simply a better and stronger box with a deep source of spare parts and aftermarket bits. The original transmission had done nearly 260,000km - I read many instances of failure between 250-350,000km for the Jatco whereas the Aisin has a long reputation for reliability at more than 500,000km. The transmission I installed apparently had low kms - about 80,000km.. VS a reconditioned Jatco, I’m ahead on lifespan and even if something does happen, I’ve got lots of late model wrecks to choose from for parts. Secondly, the ECU has been programmed for higher engine output, exceeding what the Jatco was engineered for (this is why Mitsubishi changed to the Aisin for the higher output Pajero engine) - if I replaced what I had with the same, there was a high probability I would be back in the same situation in, maybe, another 100,000km.. not ideal. And lastly, I can’t find anyone who has done this.. but I have seen a lot of people saying either it can’t be done or is not worth the hassle of trying - it was a worthwhile project in the end but there was some procrastinating along the way.

Gday, sorry I missed your question. No dramas if its the same transmission. You can do an ECU relearn and covered here faq.out-club.ru/download/pajero_iv/maintenance/Service_Manual_2008_2013/2013/23/html/M123114280001600ENG.HTM - once transmission is up to operating temp: In the 5th gear (D range) and with the throttle opening at 25 to 35%, drive until the vehicle speed becomes 80 km/h or more. Subsequently, release the accelerator pedal to decelerate, and stop the vehicle by taking 60 seconds or more. Repeat this process for 10 times. Check the shift shock is good, else repeat procedure.

@@TravelingBanker Thanks a lot for taking your time answering my question. Looking forward for your next programs . Best regards

I believe the bell housing and torque converter are the only difference but you could swap those over.

Torque converters are the same, only bellhousing ​@@TravelingBanker

@@horacecunningham7832 thanks for clarifying. Is the stall ratio the same between them?

Yes

@@TravelingBanker So I gather it will never work on an NP Pajero ?

@@johnnystoka6625 I don’t know the answer. If it physically fits then your only challenge are the electrics - the newer transmission ecu might not play well in the NP but you could get an aftermarket controller for the v5awf (aisin a750f)
