I posted a little intro over in General Discussion but figured I should ask my questions here.

If someone had a GT with an auto and wanted to swap to a 5-speed:

1. Is the GT tranny specific, or would any escort 5-speed work?

2. Depending on the answer to #1, what cars in particular could be a possible donor?

3. Is it fairly straight forward bolt-in, like just tranny/clutch/pedal/shift linkage. Or will there be different crossmembers, ECU's, axels, fabrication, etc...

If anyone knows the answers to these questions or possibly some I'm not asking and need to be, your input would be appreciated. While I know that just buying a car with a 5-speed would be easier, I am on an extreme budget and at 500.00 bucks I think this car could be a good deal.

i think ive learned a thing or two here so lemme take a shot at it...

1.)The GT tranny is specific seeing is how the GT has that Beloved 1.8 BP mazda motor.
2.)The 1.8 Protoge tranny should work if has the 1.8...also the miata tranny might work.
3.)There will probally be a few more sensors or a few less, or the same amount just different ones. And i dont see why the axles would be different. Maybe they are.... But as you see i drive a 1G scort, and its totally diff from the 2Gs...could someone correct me if im wrong.

I'm pretty sure any first gen Protoge will work( not sure of the years), the Miata tranny would physically bolt-up, but unfortunatley it wouldn't work in the Escort. What about Mercury's? The Topaz, Tempo or something is similar right? Where there trim levels available with the 1.8? I also read something about Kia's?!?
I really tried to find my own answers but came to the point where I needed to disscuss it with people who know more about this platform. Thank again.

I belive it is a kia rio but not sure. I just finished a swap in a lx. It was all a bolt in affair. There is a few differences in the wiring harness. You should change them. I did not. I just tapped into the harness to the neutral safty switch, and found the trigger wire for the starter solenoid.
Now the 91 had a seperate computer for the transmission. It is right by were the clutch linkage is going to be. I just left that all well enough alone and moved it over a bit to make room for the linkage.
The axles were the same for both auto and manual. The shifter boot will bolt right into your stock console. But as i said. I did this on a LX not a gt and there may be some differences. Hope this helps.

ok....any protege in the early 90's will work. The crossmember is the same. You will have to get different tranny mounts and stuff. But if you buy a manual tranny...check out my "tranny swap" guide in the "articles" section.

GT Auto/ 5

Hope this helps..... One other problem that you will have to overcome is the nuetral saftey swich. The swap guide doesn't really tell how to do this. Prolly because the swap guide was catered to the GT. I have an ELX and when I swaped out my auto I had no way of starting it without it. So I figued out where the switch was on my auto and removed it from the tranny. The wiring harness will fit it with no cutting 8) because it worked before. Just the switch at the tranny is needed. You don't need the auto shifter assembly and handle. The repair manual will help you to find it on the tranny. Might take you a while to find it in the book it, just barely shows you in the one I have. :?

No it is the earlier Kia Sephia, not the rio. the Rio is a 1.6 where as the early 94ish Sephia is a 1.8BP... Al;so any of the early BP Protege trannys is also the same.
all you would need to swap from the donor car is
Flywheel, clutch assembly, i believe the front tranny mount is different on the Autos and 5speeds but im not sure
