Also ... The '99 Montero Sport Limited uses a PCM. Integrated ECM and TCM. The A/T shifter is integrated into the PCM. Shift signals go into the PCM and that's what controls the transmission shift solenoids. When you remove the factory transmission and replace it with the Mitsu AW, there wouldn't be any way to shift the transmission.

[quoteIan the idea is to use both you but a switch in then when your wheeling and say your in 4l or 4ll but you want to start and stay in 2 or 3 or hell even 4th that shifter will let you do that in which you can't with the stock setup. [/quote]

Oh I get it. My auto has a hold button which I believe locks you into 2nd.

Stumbled across this earlier. Aftermarket TCU. Crazy configurable but expensive.

The '97-99 has the hold button, too. If I remember correctly it is 2nd.

I appreciate all the info guys! After doing some more research, working out exactly what I'm trying to get and what I NEED to get to make this all work, I think I'm going to take a good look into fabing an adapter for the transmission already in my '99.

I REALLY need everything to work as close to 'stock' as I can. Emissions is a PITA here and the people in the shops are not exactly brain surgeons. So, the simpler I can get this from an operator perspective, the easier my life will be.

Based on the pics you all have posted I don't see why I can't have a simple 2-3" adapter fabed up reasonably cheap. AA uses steel for theirs and I don't see why I can't do it that way, too. That wasn't possible with the M/T adapter but this is a LOT simpler. I have a gear shop and heat treating shop here in Denver that did the V2 shafts for my M/T conversion and they've been working beautifully.

Anyway, I'll look closer into this and as long as I don't find anything weird in the next couple days I'll start working one getting the parts for measurement and CADing the adapter and shaft up.

SO, AGAIN, its going to cost a chunk to do the first one but subsequent ones will be cheaper. I'll do a couple for myself; one for install and a full spare. If anyone is interested, please let me know. Once everything is set up its a LOT easier and cheaper to run three or four or five. I probably won't ever do this again so ....

Before I do this, though, I'll talk to AA and see if maybe I can work a deal through them. Most likely, though, I'll just do them myself.

What I would like, though, are opinions on whether this transmission will hold up to 37"s. I'm not worried about off road - there'll be plenty of gearing there. I don't THINK there'd be any issues running 5.13s, but ....

I hated that trans for the entire time I ran it(75k mi.). On 31x10.50 km1's, and the torque converter felt a little weak/slipping toward the end, too.

If that's the V4A51(INVECS-II) that I had in my 01 Sport, it's the one that-well, here's copied from Wiki-

Adaptive Shift Control software which monitored and "learned" the driver's habits over time and adjusted the smoothness or aggression of the gearshifts to suit his or her driving style

Maybe it's just the way I drive, but it never seemed to work the way I expected.

Off-roading was the same way, I never seemed to be in the gear I needed to be in.

My 2 cents, swap the aw4. Parts are more available, run the manual controller, be in the gear you need. Put your resistors in to fool the computer and have no trouble codes.

Thanks, Danny. Mmmmm. <img src="/forums/images/graemlins/frown.gif" alt="" />



"1999 4X4 3.5L trans is compatible with only 1999 to 2000 (to 9-2000 production date) V4A51 models"

I don't think the '99 actually had that. When I've talked to the techs, I got the impression the adaptive stuff came latter.



I have this in my '03 Limited, but that's the Montero 5-speed A/T. It is SUPER annoying, but A/Ts in general irritate the crap out of me. 30 years of driving a M/T. <img src="/forums/images/graemlins/smile.gif" alt="" /> BTW, the techs said they made big improvements in '04 - just in time to stop makeing them. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

On the other hand, I've had it off road both in CO and UT. Never had any issues with gearing. Drop it in 1st and that's where it stays. But, again, totally different transmission.



Thanks again, Danny. So, what you're suggesting is run the Rail II shift controller with something like the TCM-2000 Transmission Controller for the TCM?

Sorry, another stupid question: Does your cruise control still work?

Emailed a shop here in Denver that deals with PCS, A/Ts & t-cases and does builds/rebuilds to get me a $$ figure on a complete assembly with everything wired. Should be interesting.

Edward

I spoke to Rory at Radesigns Products about the Rail II in regards to the V4A51 and V4AW3. As expected, it will not work with the V4A51. He said it will work with the Mitsu variant of the AW4, the V4AW3. Again, as was expected.

I also asked him about setting up the PCS and Rail II as he has it described on the web site with the switch so that one could use either the Rail II or go full automatic with the PCS. Rory said he expected it would; he didn't see any reason why it wouldn't.

This is all goodness and makes me lean back towards doing the V4AW3 swap.

Luckily, I found a big transmission shop here in Denver that sells the PCS. Still waiting to hear back from them but I have my fingers crossed that they can just supply me with a completely built and wired AW.

Ok. Got a A/T builder that does tranny builds for crawlers/off road. Got a PCS supplier. Waiting for the PCS guys to let me know what harness I need and if they'll wire up the V4AW3 and I need to source a core A/T. BTW, the A/T builder strongly suggested the Transgo 340-HD2 shift improver kit if I plan to run 37"s. No surprise there.

So, I spoke to the transmission shop that does A/Ts for the off road shops here and has worked on bunches of the AW4s for Jeeps and Toys. He asked a bunch of questions but wanted to know what gearing I was going to run, what tire size, what [email]RPM@what[/email] speed when he found out what I already drive. Stuff I'd be asking if I were building a transmission for someone. Sounds like he knows what he's doing anyway. He strongly recommended running the Transgo 340-HD2 shift improver kit if I were going to run 37"s. His opinion was that w/ 4.90s or 5.13s and 37"s and the kit the transmission should have a nice long life. Oh, and a trans cooler.

So, I started reading about the Transgo kit.



For you A/T drivers, if the Transgo kit allows you to lock in 1st, would there still be a benefit in having the Rail II installed?

And, I think I found a transmission. Going down to take a look tomorrow morning. Mitsu Montero Sport - manufacturer's tag is Asin Warner 30-43LE. Still have the Mitsu VIN tag, too.

Hey ES,

I had this kit put in mine last year. What would be the difference from the one above.
