05 6 speed tranny - Toyota Nation Forum : Toyota Car and Truck Forums

What is the model number of the 05 6 speed tranny for the corolla? I just got one with 10,000 miles on it with a bad input shaft bearing, toyota doesnt want it. So I have a free tranny, but i was wanting to mate it with a 4AGZE. I know the bellhousing is different, but could I modify the holes and make new bosses?
Or should I have a new bellhousing made?
Also, what is the most amount of power these trannys can handle?
The 4AGZE I decided on because I have heard stories about how the 20V head creates a turbulence with a turbo and hinders your ability to make power like the 16V head...is this confirmed?

Anyways, thanks for the help, I really appreciate any new knowledge!'

dunno bout the tranny, but the 4a-gze is always better for forced induction, becuase thats what it was made for

Are you sure the bellhousings are different? They *might* be the same. Just doublecheck.

Anyway, the 20v head is better for making power with turbo than a 16v head.

it's a C60, will not bolt to a A-series engine

Some of the later 4AGE Blacktops use a version of the C60. Yes, it will. The bellhousing might have changed in '98 though. So doublecheck.

^^^
I was thinking about that, but I wasn't sure so I didnt want to say anything.

How strong is the C60?
What do you think about getting one into my AE91?

Actually, if you're gonna go with a 4AGZE get the GZE transmission (can't remember the code but I think its an E152 or a C150) The C60 requires the ECU for its original motor to run properly, not sure why but I think it will only run 5gears if you don't have it. Plus the GZE transmission is stronger and heavier than the C60 and its able to take more punishment.

ice_d_mugg · 09-19-2005, 10:28 AM

im not worried about the ecu in any case, i will be running a standalone as ive realized the differences in the ecu and the engine.
im also not really too worried about how the c60 will hold up under punishment because it was free! haha!
its only got 10k on it and the input bearing shaft is bad, toyota gave the people a new tranny and never asked for this one back, so dad brought it home.
but if there is any mods involved to make this tranny work, i will definitely post a how-to.

thanks!

I don't think I made it clear enough.. the "transmission" won't run without the ECU.. the motor will. You can run any standalone you want, but you'll have to run the ECU just to run the transmission itself. I've heard of enough people having to run the 20V ECU besides the 16V ECU just to run the 6spd transmission.

In any case, you'd be better off running a C52/C56 than the 6spd but it be just better to run the GZE transmission as its already stronger like I said.

ice_d_mugg · 09-20-2005, 08:17 AM

ren, this is a c60 from the 2z celica/corolla/matrix, would this be the same concept? running a 2zz computer alongside the standalone to run the tranny?
its not that you didnt make yourself clear enough, the concept of it just didnt get through. and i was kinda in a hurry, so i apologize.

i also agree that the gze tranny is stronger, they can really take a beating, but ive been getting these c60s for free, just having to fix a bearing here and there, and i just really cant go wrong, but as far as forced induction goes, ill be mainly staying arould the 2zz's stock power level about 90% of the time.

i talked to dr tweak and he kinda helped me change my mind about running the gze, so i believe ill run the 20v instead. i agree with him thats why audi turbo engines have 20v so i dont believe they could be wrong?

***REN69*** · 09-20-2005, 04:12 PM

Actually the GZE is a better motor for turbo than the 20V motors. The silvertop 20V is probably better for turbo than the blacktop, but the GZE already has stronger internals and can take more boost than the 20Vs can.

ice_d_mugg · 09-20-2005, 05:29 PM

i was talking to my dad, who is a toyota master technician, about that ecu issue with 6th gear, he said the c60 from the 2zz celica has a mechanical 6th gear and the only electronics on it are the speedometer sensor and the reverse light sensor.

also, i just want to clarify which c60 we are talking about, are you talking about the c60 from the bzr levin? because this is the new c60 from the celica/corolla/matrix 2zzge.

That's correct. You need to check that info Ren, I've never heard of such a thing. A manual tranny is a manual tranny, you put it in gear and let the clutch out, and the gear is engaged. There is nothing an ECU can do about that. (An auto tranny is a different story). There may be a 6th gear sensor that affects the *engine's* operation, but I don't even know about that.

Anyway, about the GZE vs 20v debate, the best setup is a GZE bottom with a 20v head. The 20v head is the best. The GZE internals can be used with the 20v so that's a non-issue unless you really don't want to rebuild the engine. The one thing that the GZE has that other 4AGEs don't: oil squirters. Or so they say.

***REN69*** · 09-21-2005, 07:58 AM

I believe small ports have oil squirters too, I was under the impression that from small ports and up (or before I think), all 4AGE had oil squirters.

And yes, I was mainly referring to the C60 on the 20V Levin and Truenos, didn't know that the C60 was changed for the 2ZZGEs.

ice_d_mugg · 09-21-2005, 09:06 AM

so in that case, as far as an entire engine, the gze is the one to buy, and then find a 20v head to optimize the setup, correct?

where could a person find a 20v head that isnt warped or cracked?

also, ive heard the story about how the valve relief pockets in the pistons of the 16v doesnt match that of the 20v, or is it a different story with the gze?
either way i dont care a whole lot for the 8:1 comp on the gze so i would raise it to 9:1 for a little better drivability, this car wont see more than 4lbs boost for 90 percent of the time, and the most it will see is 14, with the help of an fmic and a nitrous bar on the intercooler, also, with the help of a water injection kit.

i see these as necessary to boost the power considerably, but also to do it safely, without detonation on any fuel that i run. and these will be short bursts of that 14 lbs, as in just a couple gears then we are back down to 4lbs.

so this is also why im not as worried about the strength of the C60, it wont be seeing high power all the time.
