Thank you Adam,
This is a fun project and should offer to be a pretty good multi use vehicle. I really want to get my 6spd into something but once I realized the Eclipse ECU will shift the Gen 3 trans I got to try it first.

Looking forward to seeing this thing back on the road with the new engine

Hours of bookwork. Primarily the internal speed sensors and shift valves are all the same parts between the FWD and Montero transmission, as well as many Volvo, BMW and Toyotas as well.

Good to see you here Shaun, Thank you for getting this Pajero to me.
I got a major step done yesterday, the first trial fitting with the engine and transmission into the chassis.
First time out in the sun when mated together.
It really will go in there.
Using the jack to guide the back of the transmission.
I am utilizing a Gen 3 rear mount with the original Gen 1 type crossmember that this Pajero had.
I have the option of Gen2 crossmembers which have a bit different positioning should I want that.
I was surprised it looks like the crossmember might need to be in the forward position. Being we have guests were arriving for a party that I was the host of I kind of had to finish up this 4+ hr session.
I will get back to this once it is climbing above freezing out.
My goal for today will be verifying just where I want this to sit, then making new frame brackets for the engine to sit on, it kind of looks like they will be pretty much standard Gen 2 like.

Humm, forgot to post a few images from the top.
Examining wiring diagrams?

Yes as part of it, other documents were part of it as well. My final decision was made by checking part numbers of the shift solenoids within each transmission. It looks like Asian uses the same solenoid in most every new style transmission made be it for BMW, Volvo, Toyota or whoever. Being what the PCM really does not know what the solenoid is mounted in it really just matters that there are the same number, such as a 4 speed auto has 5 solenoids and the 5 speed has 6 of them.
From there it will be tuning to get the shifting just right, this being something that Mitsu did not do in the first place so I know it will need to be addressed once this is driving which is more than a few months away.

Is that also the same for the Jatco 5 speed (gen 3)?

The 5 speed I am using is a Gen 3 which is an Asian transmission.

Maybe its a terminology difference, but the auto 5 speed in my '05 is a Jatco (Nissan 75%, Mitsubishi 15%, Suzuki 10% ownership, ). Didn't know there was an Aisin (Toyota 51% ownership) 5 speed in any of the Gen 3s...

I would sure like to see you generate any proof of that.
Mitsubishi has used Asian automatics from back when they were Borg Warner in the late 60s. The name was changed when the new factory and corporate offices were built.
Jatco transmissions have crept into the newer FWD based cars since the Renault buy in. Mitsubishi has been producing Kei cars for Nissan for years and these have Nissan supplied transmissions.
Both the 4 and 5 speed automatics in Sports and 3rd Gen Monteros are the same family and are Asian built units.
I have purchaced new shift soliniods for one of my Gen 3s and it is in an Asian box. FWIW the transmission parts pricing is cheaper through Chrysler, they use Mitsubishi part numbering in Jeeps and the parts come in a mix of Asian, Mitsu or Mopar packaging. Never have I seen a Jatco part in a Pre 2008 Mitsubishi.

Looking for that thing i just had in my hand...
I thought i had read somewhere that the V4A51 and V5A51 were Mitsubishi made, super cool to know the car PCM can run it. I felt that mich of the MIVEC would be wasted on a 4 speed, i really think the 5 speed made a HUGE difference in the Gen 3 more so than the 3.8 itself did.

I do wish the upper gears were closer together than they are. I am curious to see how this combination works out. This chassis has 4.88 gears but I intend to change to 4.22 which should work well with the 5 speed. My reasoning is my Mighty Max was great to drive with that ratio.
The one thing I am not sure I like is the Gen 3 transfer case, it is such a huge blocky case. If I had another SR transfer I would swap to it in a heartbeat. I want to reduce how much body lift is in this, 2" now. I should be fine but will need to re-route the rear heater hoses from out of the tunnel to do this.
