anyone know the tranny code for a 1989 Toyota Corolla SR5 (4-AF) 5 spd, carb 1.6 L, , manual 2Dr, FWD ??
I am buying new tranny seals, replacing a half shaft, and the auto-parts store needs to know which model trans. Is it a C-52??
where on the car, trans, extc, ddi they hade the damned code/?
Car is a California Model..
Thank you..

On the other hand, the C-52 has two starter bosses, one in the front and one in the back. The normal 1.0 kW or 1.4 kW starter can be bolted in place on the front position under the exhaust manifold. The 1.4 kW starter from a supercharged MR2 can be bolted to the rear boss. I have seen C-52s that have the bolt holes already drilled and tapped for the starter in the rear position and I have seen others that need to be drilled and tapped but the mounting points are there.

from this:
Identifying C-5X Transaxles
When you are shopping for a used transaxle for your car, look closely at the shift selector shaft. When looking at the transmission from the "left side" (small case end towards you, bell housing away from you, differential/axle stubs to your right), a FWD transaxle will have the selector shaft exiting the case on the right, just above the differential. A RWD transaxle will have the shaft exiting on your left. (This only applies to a C-50/C-52.)
A C-50 and a C-52 look very similar and they are very similar. They share many parts. The key factor is that a C-50 has a boss or hump for the starter motor on the front side of the transmission case. (The front side is away from the differential, or if looking at one on a car, the exhaust side of the engine.) On the other hand, the C-52 has two starter bosses, one in the front and one in the back. The normal 1.0 kW or 1.4 kW starter can be bolted in place on the front position under the exhaust manifold. The 1.4 kW starter from a supercharged MR2 can be bolted to the rear boss. I have seen C-52s that have the bolt holes already drilled and tapped for the starter in the rear position and I have seen others that need to be drilled and tapped but the mounting points are there.
A key advantage to the rear position is that if you bolt the starter to the rear side (or intake side) of the engine, it opens up a large space to add a turbo. You can still fit a turbo with the starter in the front position but the starter will only last about 3000-5000 miles until the varnish has melted off of the windings and then you get a no start condition. (Guess how I know?)
C-50/C-52 Differences
Every C-50 and C-52 that I have seen that came from an AW11 MR2 had the 4:311 final gearing. I have seen FWD units with both the 4:311 and the 3:722 final gearing. The C-52s have some stronger parts. The 1-2 shift fork was upgraded and is interchangeable. The C-52 has a larger diameter input shaft where fourth gear rides on its bearing and hence has a different bearing and gear. Syncros have been upgraded over the years and the later ones are much better. The later 1-2 syncros can be directly dropped in to an early C-50, but third and fourth require some additional parts to make the swap. I don't think the fifth gear has ever changed.

If you really want to get rid of the pesky starter heat soak problem, the best solution is to relocate the starter to the intake side of the bellhousing.It's also a great way to make a ton of room available on the exhaust side for a turbo! All AE92 GT-S models should have come from the factory with the C52 transaxle.
How can you tell? Pop the hood, and look at the tranny's bellhousing. There should be one starter mounting boss (hump) where the factory-located starter is. See it? Now, on the opposite side (intake side), you should be able to see another hump, approximately at the same height as the exhaust side hump.
Now that you've confirmed that you have the C52 tranny, you can go ahead and begin the starter relocating process. Be warned that to do a proper job (is there any other way?), you'll need to actually pull the tranny, pressure plate assy, and flywheel. Why? Because you need to access the "rear end plate."
Parts Needed:
28100-16050
1.4 KW starter from a Mk 1 (AW11) MR2 Supercharged or early AE92 with 4A-F(E) engine, or
28100-16130
1.4 KW starter from a late AE92 with 4A-FE and MTM
11355-15070
Rear end plate from AE92 with 4A-F(E) and MTM

for a couple bucks,, locating re-locating the started wouldn't be a bad idea, the bastard is under the freking intake, in the worst freking place possible, since it has to starter humps, that would be nice,..
GoD$$#$### have to wait till it needs a clutch,,, then need to swap sides, also would need a new plate... I hope to freking god (i'm a freking aethiest, agnostic person) that by then we have a new car..) !!!

I'm very suprised that you have a C52 attached to a 4AF, but if it has two starter bosses, then it is. Either way, the axle seals and most other parts are the same for all C-series transmission.

wrong,, they are all not the same...
I am having some seals ordered and they list about 6 diffrent part numbers...
and also, btw, on each side of the trans, the axle seal is a different size too...
I got a list of those part numbers, and when I go back to pick up the parts, I have to tell them which trans I have..
I went through their computer and parts books at CarQuest with the parts guy..

I should not be,,,,, as I am just trying keep an old POS car with 315,000 miles together, I should not have to look for parts numbers,,, the morons who write the auto mauials make people look for info they neglect to put into the books.. and btw, the morons who write the code for the computers at the auto parts stores need a kick in the balls too..
