what trim models came with a c51 Transmision? my car has a c52 and my transmission is about to die... the c51 is supposed to be more hwy friendly.. ( i drive around 120 milles everyday)
I'm not sure on what the final drive of the c51 is, but the c52 is one of the better options in the US for highway driving. The final drive of the c52 is 4.058. I'm not sue about the c51, but the c56 that came on overseas engines had a final drive of 4.312. This engine came attached to silvertop 4ages and some blacktops. These transmissions are much smaller in size than the c52 and are very durable. The odds of finding one on ebaymotors is pretty slim without buying an engine. I hope someone can chime in about the c51 though, I'm looking for a new transmission as well since my c50 is on its way out.
the 4age paired c52 has final drive at 4.312 not 4.058 wiki is wrong in that regards. the only difference in the c52 (gts spec) and c56 is 4th and 5th or was it 3rd and 4th, idk its one of those two or somthing like that, but it has to do with different ratios.
anything C that doesnt have a 4age had better highway speeds. my corolla was pretty close to 4k rpm at 70ish mph. my paseo is around 3400 rpms around 70ish mph. and im sure that anything with a 4afe or 7afe in it will be more highway friendly then anything that came original FWD with a 4age.
or you can pair up a E series tranny, i think donald says he spinds only 2,800rpm at 70ish mph.

according to that, the c51 would be better for cruising, and the c56 for performance..
this weekend i found an 89 corolla station wagon.. it had a c51 transmission ( fut over 290k milles).. i do not know the trim level.. because it had no dx, gt, st, gts... any ideas what trims had a 51 ( in sedan, coupe or station wagon). thanks
If the car is FWD, and has a 4A-FE engine, then it has the lower final drive ratio, and that is the one you want.
What car/engine do you have?

My '89 GT-S with the 4A-GE and matching gearbox was turning about 3700 RPM at 75(maybe 70) mph. The same car with a 7A-FE engine swap and matching gearbox, was turning about 3150 RPM. I can't remember the exact figures, but it was just approximately a 500RPM difference. Same wheels and tires.

I am not sure, but I think only the ones from a 4A-GZE.
Even then, it is heavier than the "C" series gearbox, so you will be lugging around more weight.
The lower final drive will probably sap the torque from your engine and cause you to slip the clutch more than is healthy, in order not to stall on move-off.

What car/engine do you have?
I own a 91celica st. engine 4afe ( st generation) with a c52 (manual transmission).. I get 70 mph at around 3800 rpm.. with a c51 transmission I'd get around 3200.. ( I drive around 120 miles a day)
.. so any car with a 4afe comes with a c51? ( I know I'll love that transmission)
Sounds like you have a 4.3:1 final drive.
My suggestion, get a 5spd from an AE101 Corolla (93 -98).
I have heard that they have stouter gears than the earlier gearboxes.
That is just hear say, but they will be newer and probably have less miles on them.
Actually, what you need to do is get a 7A-FE engine and gearbox.

7afe engine and transmission? that's gonna be lots of problem. any trims i should look for in the junk yard?
That is a straight physical drop in, mounts and axles bolt straight up. The wire harness is a different story, it will require modifications.
Some people have done it using the original 4A-FE ECU and wiring.
Using the 4A ECU you will need to swap out the distributor. Some of the 4A-FE distributors will work, I think, but I am not sure which ones.
Using the 4A ECU, you will loose the protection of the knock sensor and the 4A has a higher rev limiter, so you could possibly over rev the engine if not carefull.
The cars with the 7A-FE are '93 - '98 Corolla DX and wagons (AE101).
Celica ST, what years, I am not sure.

The transmission you want with the tall 0.725 ratio was installed on the front wheel drive '84-'87 Corolla 4 door sedans with the 8 valve 4ALC engine. I had an '86 with that transmission combined with a 3.7 final drive ratio. So at 60 MPH the motor was doing only 2400 RPM and the car got 38 miles per gallon!
I am not positive, but I've never heard of any 16 valve 4A motors that came with the .725 ratio transmission. Example: I have an '89 front wheel drive wagon with the 4A-F motor and it has the shorter 0.815 ratio so at 60 MPH it spins at 2700 RPM.
