Swapping different year transmission problems

The transmission on my 1995.5 3.4 tacoma went out. I picked up a used transmission w/o transfer case on Craigslist from a 99 tacoma w/ 3.4

The plan was to pull the old transmission, and throw the old t case onto the new transmission. However the back of the transmission is different for both years. So the transfer case won't fit into the "new" transmission

It might be a long shot, but would I be able to seperate the backhalf of the transmissions and switch them between the different years? I assumed all the r150fs were the same. Or is there any way to tell if this guy screwed me over and didn't actually sell me the right transmission?

Everything looks exactly the same except for the electrical connection in the right side of the transmission, and what looks to be a small breather tube/cap on the base of the 95.5 gear shifter

 

Well I took the old transmission apart, and it looks like swapping them around is impossible or way above my pay grade.

At this point Im gonna dig around and try to find a t case that will fit the 99 tranny.

Does anyone know how the different r150f groupings work?

 

It has to do with transfer case. one is a j-shifter the other one isn't. I believe

 

Are you sure you picked up a transmission from a 4x4 tacoma, a non 4x4 transmission won't mate to your t-case at all.

 

Yea it's a 4x4 tranny. The PO had dual cases on it.

 

Pictures would be a great help

 

So I've looked around and im worried this guy didn't even sell me an r150f.
Supposedly he sold me a 99 tacoma r150f transmission out of a 3.4

Marlin crawlers website seems to seperate the r150 into three year groups. Today I went to look at a t case from a 98 tacoma, and again it wouldn't fit. I saw a picture of a 99 tacoma t case online, and it looks the exact same as my 95 case, and the 98 case I saw today.



This is a photo of the back of the "99" transmission on the left, and my 95 on the right. Both have the t case removed.

All of the transfer cases I've seen from my 95, the 98 and the 99 I saw a picture of, seem to have female connector tube that appears to slide around a splined shaft that comes out of the transmission (you can see it below, it's a picture of my 95 transmission, except I seperates the two housings)

However my "99" transmission, doesn't have a spined shaft out the back, instead it looks like it has the exact opposite, a female connector tube.

 

Can't see your pics, but I just pulled a j shift transfer case off of a 98 4x4 manual and it has the female connecting tube like you said.

 

Picture aren't showing up.

 

Hers the picture of the two transmissions. My stock transmission is on the right, and my "new" transmission is on the left.

Both input shafts are the same length, and the only major difference is that the stock 95 transmission has a spined shaft sticking out the back that the transfer case slides around. And this new transmission has a splined sleeve that a transfer case should slide into

 

This is the stock transmission (with the back housing removed). But you can see at the very top the splined shaft that sticks out the back.

Im thinking this is an older model that was paired with a chain driven transfer case, unless you can modify the transmission to work with different cases.

 

The new trans has a seal adapter for a dual case setup, that's what the big round looking thing is. You should be able to swap the back half of your old trans onto the new one. That seal adapter is pounded on there and secured with locktite so it's not coming off.

The inputs are both male and should have a female adapter tube, if it's not on the trans output, its stuck to the tcase input (most likely scenario).

Don't use this in less you are going to install duals....



Which by all means this makes it a good excuse to do that!!

 

I feel like that aluminum part is a sleeve that can be transferred over. Anybody confirm?

 

It's pounded into the back of the trans output and usually coated with red locktite. You aren't getting that out without damaging the transmission housing. That sleeve is aftermarket and part of a dual case seal adapter.

 

So I split the two housings, and I need to get rid of this sleeve. How do I go about removing it? I'm assuming I have to completely remove the output shaft and re use the old one. Is there anything special I need to do or not do? Messing around with the inside of my transmission has me extra paranoid

That sleeve should slide off.

 

Sleeve could just be stuck on the spline. get some penetrating oils on there, kroil is best if you have it or pb blaster if not.
