2nd Gen Tranny Doesnt Line Up in GSL
I have the 12a front cover on and the 12a engine cross member on the car.
When we mount the engine in place the tranny does not come close to lineing up with the shifter area.
Its like it has to come forward a bout 5 inches so that the shifter fits into the stock location.
I have not heard of anyone else having the same problem so i dont know whats up????
Its a S4 Engine and tranny.
The car its going in is 81 GSL.
Im starting to think i got a 3rd gen tranny on a 13b Turbo JDM.

I assume you are swapping a 13b turbo setup in? and a turbo trans? If you are using the 12a crossmember you need to either modify it or get the racing beat engine mount made to put a 13b in a 12a car. It moves the engine forward about a inch to sit where it would if you had a SE cross memeber. Also if you are using the T2 trans the shifter must be modified to sit exactly 3cm forward (done by modifying the shifter rod and installing the shifter tower from a FB trans)

I PM'ed you back with instructions on how to notch the transmission tunnel to clear the tranny. You should be able to perform that with minimal tools in under an hour.
I'll try to get you a pic of my notch tomorrow.

So to summarize what I understand for mounting the engine and tranny...
Take a TII engine.
- Put a 12a or GSL-SE 13b front cover, and a GSL-SE 13b oil pan on it
- Get the front crossmember from RB to fit it in your previously-12a car
- Replace the tailshaft housing or notch the shifter hole
- Drop it into place
- Have custom driveshaft machined to fit
Does that about cover it? The RB crossmember and 12a/-SE front cover mount the engine up front, but how does the transmission mount work? Does the stock 12a or stock TII mount work with the engine/tranny in this position?

Stock 12A tranny mount will work if you are using the 12A tranny tailshaft (I didn't know this would work for a T2 trans, just thought it worked on an N/A trans). If using the T2 tailshaft housing, you need to custom fab the trans crossmember to use the T2 trans mounts, or modify the FB trans mount to bolt to the T2 trans. T2 trans, like the N/A FC trans, has the mount bolts a little closer together VS the FB trans.

-GSL-SE 13B front oil cover, GSL-SE oil pan with oil pick up!!!
-get the front cross member from RB to fit in the 12a chassie
-replace tail-shaft housing that has about 8-10 long stud bolts Do not NOTCH tranny tunnel!!!
-Bolt everything up drop it in the car use 12a tranny mount
-Since your using the turbo tranny you have drive shaft made or modded u joints on the back of the turbo shaft.

You basically remove all of the stock tranny mount gear from the TII, and build a 3" x 3/4" x 3/4" mount out of steel or aluminum.

It is easy to mod a stock 1st gen mount to fit the FC trans. It's only slightly more involved to mod a stock FB crossmember to accept the FC's triple mounting setup. The latter actually helps stiffen the engine/trans against twisting, taking some stain off the engine mounts/mounting bracket and front cover.

Having read that thread, I can say I do not agree with your simple mount idea. Without rubber between the trans and crossmember, there will be a lot of excess noise and vibration transferred to the body of the car.
