93 awd transmission into a 90.

[1ga]

Ok, I'll start out by saying that I have researched this topic and sorry for a possible repetitive thread, the only reason I post this new one is because I have limited access to the site, being a new user, so it wont let me post in the thread I have found online.

I am in the final stages of the swap, I heard it was done before and I made the mistake of buying the 91+ shifter cables. 150$ that maybe wasn't necessary to spend.

I'm down to this, I have the 91+ shifter cables in, I have the Transmission brackets from a 90 and a 91+. I have the Shifter base from a 90 and a 91+.
The problem seems to be that the 91+ shifter cables are too long, they sit too far forward and I cant pull them to mount them on the transmission bracket.

So now I have to switch cables Im assuming, but what is a known combination? When I had the 90 cables in before, I could only get the car to 1-2-3-4 but no 5 and reverse.

Did you adjust the push rod in the car.

No I haven't I'm in the process of putting the 90 shifter cables back in. I'll keep you posted what happens after lunch.

What shifter cable bracket on the transmission are you using in unison with which year shifter cables? They have to be matched specifically (though I sadly cannot recall in which way) otherwise you will be left with the inability to access 1-2 gears or 5th-Reverse.

Back, It started raining, this is what I'm using:

90 shifter cable/transmission mounting bracket
90 shifter cables
90 shifter and base

With this set up I can shift 1-5 and get reverse sometimes with the car not on.
I would take pictures, but nature is telling me to screw myself..

On the shifter cable mounting bracket there are two rubber grommet like washers, on the side facing the body there are no rubber grommet washers, just metal washers, I find if I loosen the bolts that mount the cable bracket on the transmission bracket a little bit it allows some 'spin', this made it a little easier to get into 5th and reverse. Prior to this I had to take the 91+ shifter and base out in order to mount the cables into place.

Before all of this I had:

91+ shifter and base, Cable mount and transmission bracket and 91+ shifter cables and I couldn't get anything mounted nothing would line up.

I found on every thread that I have to use 91 everything when putting a 91+ transmission into a 90. I'm really confused. because there's no way I can get 91 anything to line up

The hardest gears to get into are 5th and reverse. The tranny shifted smooth as butter in the other car. I'll find out if it wants to go into reverse when It's not raining and I can get the car started. I really wish I had the luxury of having a garage..

I think the problem is with the rubber grommet washers on the shifter cable bracket.

Also the cables seem to be too tight for comfort in the engine bay, They do not kink, but it sure feels like there should be less tension. Will adjusting the push rods make the tension go away? How do I adjust them?

I couldn't test because the car was not running, but it seems like I have to adjust my clutch. but things are looking better.

You should have no problem using 91+ cables with a 91+ base. That's what I'm using seeing as the 91+ cables and 90 base wouldn't let me go into 2nd or 4th.

That's really strange.

The 91+ cables are way too long for me.
I tried to mount the 91 cables to the 91 shifter base, with the the 91 transmission and cable bracket already mounted and secured with that clip, but it was like I had to pull on cable from inside to get where the cable mounts to the shifter base to line up. I kept tuging on the cable.. So I undid the clips and mounts under the hood and tried securing the cables from inside the car to the front of the car. It ended up that I got it mounted but the lines were severely kinked. So I gave up.

So I switched everything back to 90, (using transmission and cable bracket off the 90) and lines up almost perfect, I can shift into all gears with ease 1-5 and I can find reverse ( a little tougher than when this transmission was in the 93, but seems liveable) I can only shift into the gears when the car is off.

This is my new problem. Before I discuss the problem I want to shed some light on the history.

I put an act 2600 clutch in and act lightweight flywheel last year, After I did the clutch job, I had to adjust the clutch adjusting rod about 360 degrees and shimmed the pivot ball I could then Shift into all gears fine while running. Since then the car hasn't drove more than 40 miles. I came to realize the 90 tyranny that was in it was junk (shifted like crap) Since then the car was being constantly worked on, (bad ecu caps, and other fuel issues) So deciding the 90 trans was junk I put the transmission from my 93 in and junked the 93 body, keeping some parts ( the 93 body was rotted out severely while my 90 was in amazing shape)

So, While the 93 transmission was off, and ready to go in, I converted the shimmed pivot ball from the 90 transmission over, cleaned it up inside, Painted the outside of it, made it all pretty, checked the fork for bends, I put it all in.

The problem is now no matter how far I Adjust the clutch adjusting rod out (to where it almost falls out of the C thing) The clutch doesn't want to disengage while running, I can try starting it in gear, and lunges forward.

I have read a lot of threads over the years and it seems like a fix for this would be to properly bleed the system. My clutch has decent pressure, but with these cars I don't think that means anything. I should get a OEM slave cylinder.
My run down is this

Flywheel step height? I don't think so, because it did shift fine while running with the clutch adjusting rod adjusted and pivot ball with the 90 transmission in.

Worn out Clutch pedal assembly? Possibility, Will inspect.

Master Cylinder: Maybe if it just went out while the car was sitting and being worked on for a year, but I doubt it.

I almost wish I would of stayed with the stock clutch, pp, and flywheel, not being able to drive my car for this long i don't think its worth it.. I'm really hoping this is as easy as bleeding it.

Thanks for the help guys, I'm going to start with bleeding the system then go from there, I'll keep you posted, I really want to drive this thing again, It was so much fun with the greddy exhaust. Damn I miss it.
