HELP: Auto to Manual 94' Corolla

[Tougerun16]

Hi I have an automatic 94' Corolla DX (7AFE) and I am going to swap a manual tranny in it. I'm grabbing a C50 trans out of a 94'ish Geo Prism from the junk yard. I was wondering what I could use from the Geo and what I need to completely swap/convert my Corolla. Thanks a lot!

Welcome to the forums! There was a thread about this a little while ago. It an be found here:

http://www.toyotanation.com/forum/t332240.html

To roughly quote my post in that thread - I've never done a 5-speed to auto swap, nor do I know all of the ins and outs involved, but off the top of my head some are the parts you need will be:

* 5-speed gearbox (obviously)
* Shifter
* Brake pedal and clutch pedal
* Clutch disc
* Pressure plate
* Speedo cable
* Clutch cylinder
* Slave cylinder
* Clutch lines
* Flywheel
* Throwout bearing
* Transmission mount
* CV axles
* ECU
* Possibly a 5-speed oil pan

It would most likely be cheaper and definitely easier to start fresh with another Corolla, one with a 5-speed transmission, but if you're determined then anything is possible

Good luck!

Well This is my first post here but i just finished my swap last week.
Best way of doing this is with a junkyard car or buy a donor car,
mine was a 4afe tho. Here the list off the top of my head.

- Tranny and tranny mounts
---- Reverse light wiring harness
---- The bolts that hold the manual tranny to the engine, auto ones are not the same(too short)
---- cv axles are the same, at least for the 4afe

- flywheel, clutch disk, pressure plate+bolts, throwout bearing

- shifter assembly, cables, and the plates(where cables pass thru body) and rubber pieces that go with the plates.

- clutch petal mounting bracket, master and slave cylinder and the line connecting them

- manual ecu

- tranny fluid, engine coolant(your going to have to disconnect the radiator)

- engine support bar or related to hold engine in car

- a lot of patience

This is the best advice. You will THINK you have all the parts and then theres some more you need but the junkyard crushed the car you were taking parts from and all thats left is automatics.

Have fun on your project. Dont forget to install a fresh rear main seal before you bolt on the trans so you wont leak oil later.

Thanks guys. What can I pull out of the Geo that will fit into my Corolla? Well besides the tranny, clutch, and flywheel of coarse.

Every thing you need basically, the shifter boot might be slightly different but that'll be the only difference

Nice, will the 4afe ecu work fine with my 7afe motor

[Steelballz]

no, the 4a is 1.6 and the 7a is 1.8, so there will be fuelling issues amongst other things.keep a lookout for a 7a-fe ecu

It cost me 600 to do it. I did it while doing a silvertop swap. Rewiring is key.

Just wondering, what exactly will need to be rewired?

[trife96]

I've done this swap twice.

A couple things not mentioned though, the engine backing plate. Also motor mounts for the Prizm on the driver side on the tranny are slightly different. You will need the bracket that bolts TO THE TRANNY. They are slightly different or you will have to wallow out the hole Also the rear mount "U" bracket that bolts to tranny is different from auto & manual. Also shift cables.

The main difference between ECU is the body plug connector (3rd plug). It's either 22 pin or 12 pin. Also the 7AFE and 4AFE harness is slightly different as far as sensors go....along with the fact that manual and auto are different so it's best to get a similar year model ECU and harness for a manual. Even still the body plug will have to be cut and spliced. Also wire up the manual clutch pedal switch. The plug wire colors will match up for pretty much all the wires and you will have a few remaining due to the Auto ECU wires not being used. a couple of those wires will be the wires needed for the clutch pedal switch

Can the swap be done using the 3 speed auto 4afe ECU? How can I get that to work?

Also, do you happen to have any pics of some of the needed parts you mentioned (bolts, brackets, plates, etc)? I just wanna make sure I have everything while I have the chance to get it and it really help if I knew what to look for, thanks!

[trife96]

^ I can't say it won't work...but I do know the pinout for the ECU from auto to manual has quite a few differences...not just in the body plug but in the engine harness as well. I klnow because I have compared the pinout diagrams myself! And it would requirte a lot more rewiring. If you want a manual...You need to get the manual ECU to simplify everything.

As far as pics go...I have only a couple when I was collecting parts. But not so much on the motor mount parts











Hope this helps

[monkeypower102]

Thanks! But now I'm a bit bummed bc I don't have the manual ECU :/

Any ideas as to how I can get around using the one I have?

[monkeypower102]

Do you have any pics of the pinouts btw?? And also any wiring stuff? Wiring scares me lol
