Default 95 JDM Trans into 05 RS. Im stumped Gurus needed! Pics included!

Ok heres the story. I bought a 95-97 JDM WRX Transmission from a guy on the boards. I ran into a few problems when I got it today. I need some gurus to diagnose the following;



My transmission is on the right in picture two. The JDM trans is on the left in pic one. Notice how the clutch forks are different. The JDM clutch fork is connected on some kind of a rod thing going through the transmission. On my transmission in the right picture, it just slips on to a little ball (which is directly under the red arrow in the right picture). Now because of the different styles, it moved the Slave Cylinder mounting point...



On the left, the red allow points to the side where the slave cylinder mounts. On the right, you can see that my slave cylinder mounts on the top. I cant just move my slave cylinder because the mounting points are different sizes so I guess I need a new one. Is this easy to do? I would also need the clutch line because mine would be to short I 'think.'



My next question leads me to the linkage. On the left side of this picture, the red arrow points to the linkage connector point thing, that was on my 05 rs. The black piece next to it is what came on the transmission. My problem with this is that they are two different sizes. My 05 mount is shorter so I need to know if the linkage on my 05 is longer to accommodate this change.

Last thing... My axles wont fit this older style transmission. This newer JDM transmission has half shafts coming out of the transmission.... My transmission did not.... I need to know if an older gc8 style axle will mount into my Hubs.


To summarize these are my three questions;

1. Is it worth it to buy a new slave cylinder and clutch line to be able to use this transmission?

2. Will my linkage mount up to this?

3. Will gc8 axles mount to my 05 hubs?

Thanks so much for all of your help.

1. this is a fundamental difference between N/A and (older) turbo subarus. you need more than just a slave cylinder and line to make this tranny work in your car. you would also need a clutch (pressure plate and friction disk), release bearing, and flywheel all made for a turbo car.

2. I haven't played with all of the linkages myself, but bet it could be made to work. definitely not the biggest of your issues.

3. I believe the outboard splines are the same for all of the non-sti imprezas. however, if you have a GD sedan, your track width is wider than a GC. your best bet for axles would be to look for axles from an 02-03 (maybe 04?, not sure when they switched to the stubless trannies) sedan, either wrx or RS.

The transmission came with an Exedy Stage 1 Clutch with a lighter flywheel and throwout bearing that was used with the transmission so I have that taken care of.

So the 02-03 axles will work! Awesome. Thank you so much!!!

IIRC, you just you need a hammer and a properly sized punch...
