Can you confirm that this is indeed an R150F? In comparing this to pictures online it appears to be but I know jack about Toyota transmissions. It supposedly is out of a 96 4Runner.

Thanks for the link, that is helpful.

According to that link the R150F did come in a 96 4Runner, so I’m just looking for a visual confirmation from someone who knows since the owner said he’s not positive.
 
i was hoping it had measurements for that tranny but it did not. bummer but it will help with the detective work for sure.
 
Is it safe to say that a Marlin adapter that fits an R150F will fit any R150F? According to their transmission website there are at least 4-5 different R150F transmissions.
 
now that is a good question.

NWF maybe worth a call, i have chatted with them before and they have a toyota crawl box now and they answer the phone.
 
If it was behind a V6 it’s an R150. That trans IS an R150 in your picture.

IIRC, there are input shaft length differences between 3.0 and 3.4 R150's. But Marlin would know for sure.

When I bought my adapter there was a manual and auto adapter. I wasn’t aware of more versions. I would guess that the adapter would be year specific since the tail housing and transfer housings may change over model years. Figure out what transfer case is on the trans.

No

3.0 R150s have a different tcase bolt pattern than 3.4 R150s except the T100. More simply passenger drop trans/tcases have different bolt patterns than drivers drop ones.

3.0s are a VF1

3.4s are a VF2

T100 being the exception since the 3.4 was still passenger drop... Have not held parts in my hand but the internets says it stayed VF1 bolt pattern until Gen1 Tundra.

So that 96 trans is for a VF2 drivers drop tcase adapter. You could use the whole trans in your setup but not just the adapter on the back of your current transmission If input shafts play nice.

Edit: Input shaft length changes with tail housing. Early is 30mm shorter than later style transmissions. Might be able to swap inputs to use the whole trans with your 3.0 clutch stuff.

I should have included the whole picture. He has converted to passenger drop, but according to the pics above this adapter is for a VF2. He doesn't sound super sure about any of this. He did say he could seperate the trans and take some pictures for me. Maybe that would be good.

In looking closer at the bolt locations on the adapter and comparing to the two tailshaft pics supplied by chambers13, it seems very likely it is indeed for a 3.4.
 
So if I get the correct adapter than this should be a direct bolt up to my 3VZE R150F correct?

Yeah if you get the correct trans-tcase adapter it will. Should be able to sell the VF2 one to recoup some $$$ if you have to buy the whole setup.
 
You could just run that whole setup behind your 3vze also (if its being sold as a package deal), it will bolt up to the engine.

Slave on the drivers side tells you it's from a 3.4 if that hasn't been covered already.

Don’t mean to sidetrack from op’s issue, but this means a T100 3.4 r150 would be the longer input shaft but vf1 passenger drop tcase bolt pattern, correct? So guys doing a tacoma SAS with toyota axles that get forced into duals or flipping the axle could just use a 95+ T100 r150 and have it bolt right up with passenger drop tcase? Might have to go outside and check my 3.4 t100 what side my slave is on, because if they used the longer input shaft but have the body of 3.0 era i guess slave would be on the wrong side. Just an idea probably cheaper than an adapter as r150’s of all kinds go for $100 where I live

You could also just use any 3.0 r150 and the vf1.

Swapping in a stock Toyota axle in a tacoma is pretty retarded though.

Wouldn’t the input shaft be too short ? or use 3.0 clutch assembly on the 3.4? i’ve had my 3.0 trans off before but never a 3.4 so i don’t know what’s all different, i might be way off, was just a thought. And i agree but there are a few first gen tacomas in my area so people do it for sure, even with ifs hubs seem skinny though

I'm not sure, but I know it's possible, lots of people put early 3.0 r150s behind 3.4s. I'd imagine you use the clutch assembly that matches the trans.
