Are all T2 transmissions the same on the outside? I know I have to take the shifter housing off my n/a trans and put it on the T2 and I also know that it will fit on the 87-88 ones but will it fit on the 89-91 ones?


Anyone out there put a T2 trans in a FB?

 

above pic is of a -se trans, just posted it to show what i mean by "shifter housing" (that thing that has 4 bolts holding on top of the trans)

 

I have a T2 tranny that is going into my FB, I believe you can use any of the second gen trannies.. You just have to change the shifter linkage & make a spacer for the tranny cross-member.

Also I believe you have to run a different flywheel.. I don't know because i am running a TII engine...

Same here . What series T2 trans do you have? 87-88 or 89-91?

 

I was told it was a 90 TII engine.. But since i didn't pull it out i don't completly know..

look at the OMP and look for wires comming out of it. 89+ have electronic omp, the older ones just have the rod that goes to the throttle body.

So you got the engine and trans out of the same car then?

 

Sorry, I ment 90 TII tranny not engine..

Does anyone know if a TII tranny will fit an SA? My guess to making it fit involves using an FB shifter housing on the TII tranny and shorten it so the rear bolts go into the front holes. That shortens it by 3 or 4 inches. Probably enough to fit it in an SA or older rotary cars.

Who out there thinks it will work?

 

Well, there are lots of people running FB trannies in r100s RX-2s, Rx-3..... So i would think it would work.. There would probably be a little bit of modifications to get it in.. You might have to chop up the shifting tunnel to get it in.. and of course get a custom driveshaft made..


BTW if anyone wants to give me a RX-3 SP to test my tranny in an older rotary i am game

it should fit just fine in a SA you just have to use the early shifter and rod crap... setzep there virtualy identical other than minor differences,, unless you get a truck trans froma b1600

 

??

SA's don't have the remote shifter that later trannies do, so there's nothing to swap onto a T2 trans. Or am I missing something?

 

re-read Jeffs post

 

I want to put an FC tranny in an SA using a shifter housing from an FB. (ah, summed it up in one sentence)

 

So is there an answer to my original post? I'm thinking of ordering my engine-tranny combo pretty soon and need to know what trans I want (or need).

 

My friend Bryan's SA has a TII trans in it, but I don't know how it was done (neither does he)...

 

I have a S4 (2nd Gen) box in my 85 first gen and its on a JC Cosmo 13B with an RE Amemiya clutch and flywheel

The tunnel hasn't been touched. All that was done was to use the FACTORY extension housing from an 85 gearbox and put it on the back.

 

take some pictures of the mount, i would like to see the 85 extension housings on the trans. cause i have my t2 trans next to a 12a one and they have different bolt patterns so i could not put it on. just curious

 

His S4 box is probably from an NA car.

 

I doubt its a N/A tranny in there, with that much HP and the beefier rear he put in, he would have to drive VERY carefully, hehe

 

Im trying to figure out how to mount the TII tranny right now. The mounts are a lot different and the 12a trannys mount will not simply bolt up to the TII tranny. Does anybody have any pics or can explain how to get the tranny to bolt up? I dont mind modifing stuff but if there is an easier way then I would like to try that first.

 

easiest way i know of so far is to make a offset box and the stock first gen crossmember. i am thinking about making a limited production of them cause a good friend of mine is a expert welder so i can get him to do a few for pretty cheap. and i know people would buy them up real quick like

 

What would be a sweeter deal would be pre-made driveshafts for the swap... it's fairly easy to modify the floor or the crossmember but most of us can't make our own driveshafts. In fact that's pretty much the only thing holding me back from doing a T2 trans swap.

...and the T2 trans swap is the only thing holding me back from better induction so I can make over 150hp... (cough cough 45DCOE cough cough) 150hp is kinda pushing it for a stock trans that gets regular dragstrip abuse.

What would be sweet would be if it had standard American sized U-joints... bigger/stronger, plus Granny's Speed Shop makes adapters to mount them up to the late-type "big flange" rearends. (For big power you should at least be using a '84-85 rear anyway, 'cos they're the strongest)

 

I'll have a chat to my mechanic and get the lowdown on my conversion. Will try and get pics as well.

 

Thanks AJC13B, I'd really appreciate it if we could see what this looks like. Having a hard time picturing what the trans mount should look like in my mind.

 

Here is a pick of my TII tranny with a 1st gen linkage...
