V5MT1 Confusion #930426 02/09/09 11:13 PM

Need a Spot
OK. So I bought an '89 Raider with bad syncros and I am either going to rebuild it or source some kind of replacement.

While looking for info on the box, I'm seeing references to different versions of it. -1, -2, etc.

Do these boxes interchange with each other and join to the same transfer case(s)?

Are the later boxes truly improved? If so, does a rebuild (syncros, bearings, gaskets) update an older box to newer specs? Or were there major parts/big dollar changes that occurred?

Are parts at all available for them? A quick search shows that bearing should be, but syncros?

Or, if the idea of rebuilding is out of the question, what would be a suitable replacement that would take minimal refitting?

Thanks for any help you're willing to offer.

I'm guessing you have the V6 3.0 model.

You'll want to look for the later model for the better Syncrhos and I think it has a "semi" synchro for reverse.
V5MT1-2 is in the Pickups,,,,V5MT1-3 is used 92-94,,,,
the vary rare V5MT1-6 is used in the 95-96 3.0 24valve. The 97 Montero Sport 3.0 4wd used the V5MT1-4 . They will all fit.
I'm planning on going with the 1-3 when I get the money .
This one is probably the commonist and more parts probably available. This is a very Heavy Duty transmission and as long as you use the recommended gear oil , it should last forever as a D.D. and reasonable Off road and snow.(I rec. A.T. for rock crawling).
The synchros and using the wrong oil is the problem with the V5MT1-0 . 80/90 GL-4 required-- Not GL-5 oil. GL-5 corrodes synchros in this M.T.. The front countershaft bearing seems to be the weakest link as load is on it in all gears but 4th. The parts are available, but getting more difficult to get every day.
Try salvage yard internet search to find one. M & S recyling in Sacramento probably has them ,,but I've had problems with them.

The part # is on the drivers side of the Trans case.
Your # will end in -01; -02 on it . If it's been replaced it may have -04 on it.

Look for one that ends in -06 <img src="/forums/images/graemlins/kewl.gif" alt="" /> that's the 1-3.

Do you know what year the v5mt1-6 comes from? IIRC from past threads, to fit to a 3.5 SR, you need the handshaker from a 95-96. These were the only two years with the 24V 3.0 and the MT. The 12V 3.0 trannies are different. Don't really know in what way though...

A 5-sp SR would be cool. If the uber cheap MT is from a 95-96, and you don't get it, let me know. I will be needing one before too long I sense. <img src="/forums/images/graemlins/scared.gif" alt="" />

Also, search on OldColt too. He has visions for a 6-spd, I think from a Yota.

All these trans cases are the same part # except tha V5MT1-4 that'd in one year of the M.S.
The V5MT1-6 came on 3.0 24 valve 95-96. I believe they were put in 3.5s over in OZ. That model had different / smaller / maybe conical Counterbalance shaft bearing.
89-95 used the same Cuon.Bal bearing. Parts may be harder to get on the 6.

These are a heavy truck transmission , so I would think it would hold for regular use.
If your gonna drag race than no ,,,mainly case the jump in ratio from 1st to 2nd is too great and would be practical for that purpose.

Thanks for the info. That helps a lot.

Yes, it's a 3L. It will be used as a daily driver.

I'm getting kind of tired of taking off in 2nd then doing a 2nd to 4th shift. Even so, it's better than the S10.<img src="/forums/images/graemlins/pfft.gif" alt="" />

Bellhousings are different PNs. Don't know if they bolt up the same or not. Would be great to know as it would open many more options for me when my 95 goes. Right now there are but a very few out on Car-Parts.com.

95-96 trannies also have the bigger t-case, like a 3.5 does.

all 6g7x blocks use the same bellhousing bolt pattern

starter/position may be different. that could be the change for the bellhousing part number. could be a revision in the later part and it supercedes the earlier part.

That rings a bell (housing, yuk yuk). When I did a CAPS review, I was not getting superceded PNs for the earlier ones. Maybe Stony and I'll will hook up for a beer and we can compare MTs. <img src="/forums/images/graemlins/cheers.gif" alt="" />

I think the part numbers vary on the bell housing is like the part number on rear trailing arms----different part number cause the is a hole tapped for holding a wire or braket.
Seem like the mainshafts might be the same , I'll have to recheck.
Clutch disc are all the same part # 89-96,,, ie same splines
Part #s to look at on transes on shelf at the yards.
