6G Celicas Forums

Does any one know if the 6 speed transmission from a 7th gen GT will fit the 6th gen GT?

nope, and I thought the 7th Gen GT was 5 speed, and the GTS was 6 speed.

this is true

anything is possible, but unless you have a couple grand and a kickass machine shop I wouldn't even attempt it

It'd probably be cheaper to have a transmission shop go through yours and make the ratios better fit your preference then to try and mate a 7th gen tranny to a 6th gen engine.

forgot where i heard it but ive heard you could bolt up the six speed to the 4age.

There really wouldnt be a point either, the GT gear ratios are already pretty small, smaller than the 3sge which provides a quicker acceleration. a 6th gear would only be used for top speed and fuel economy.

4age blacktop came with a 6-speed.

You can bolt up an AE111 six-speed 4A-GE tranny to a 4A-GE engine.

I believe it will actually bolt-up to the 7AFE also... soooo... yes it will be possible for the 7AFE/4AFE Celicas but I don't believe there are any 6 speed FWD trannies for the S series motors.

Yeah, it should bolt up to the 7A-FE as well. Since the AT200 and the AE111(the five speed ones anyway) both use a C52 tranny, it should work fine. I'm not sure what the number is for the AE111 six-speed tranny, but I don't think it's C52.

If you want better gear ratios, TRD Japan makes gears for the C52. They're pricey though, but probably less than having custom ones made.

what do you guys think could be done to strengthen the c52 tranny? i'm planing on rebuilding it, and tuboing the 7a. so is there anything other than a standard rebuild that i should do or get for it, other than a LSD and performance clutch?

This is right on. Most cars with a 6-speed transmission with exception to very high performance cars are only used for fuel economy. This is the case with the Celica GTS (which besides, the 6 speed tranny I thought was really slow just my opinion though) and with the Nissan Sentra SE-R Spec V...just to name a couple examples.

Although I'm not disagreeing, I'm gonna add that a 6 speed will slightly improve acceleration because of the shorter gearing. Depending on the engine's power delivery, having a 6th gear usually means all of the other gears, mainly 3rd and 4th can be geared much much shorter, in essence, quicker acceleration. Again, it depends on what engine though, because depending on the power delivery, shorter gearing can sometimes hurt acceleration.

Now that everyone provided their input, I just wanted to ask: Why do you want a 6-spd??

To match my shift knob!? Heh... I personally wouldn't see the need to, and don't really want to unless I had an engine to boot (ie: 20v 4AGE blacktop/silvertop) but that's me. Anyone else... well, I'm sure you're aware of the thinking process some people go through before they ask questions... ;]

yes, but strangely enough I have heard so many complaints about the 6 speed on the ae111's making them slower than they should be.......

btw coomer.... i'm interested in you getting a dyno run on your 20V when it's done..... i'm gonna be doing a dyno run on my smallport and we're expecting very similar numbers to the silvertop..... a guy in everett ran a 120hp to the wheels on his aw11 with a silvertop.... also, I met a guy last night who knows someone in australia selling 20V parts, including ignitors.... i'll try to get the part number first to make sure the one you got from club4ag is correct, and if it isn't i'll find out the price for you

I'm interested in dyno-tuning the car as well. I want to do it after I get either an S-AFC2 or an E-Manage, and then have a good shop do it for me. Also, was that Ken with the maroon(I think) MR2 than got 120 horsepower out of his twenty-valve?

And about the ignitor, I found one from a 4Runner that's going to work for me. It's sitting on my desk now, and tomorrow I'll drop it off at my mechanic's shop.

And Ray, I know I'm probably wrong on this, but with the six speed from the AE111, it seems like gears would be shorter, which would be nicer and provide quicker acceleration for a small engine that doesn't provide much torque or power until the RPMs are up high. That said, I wouldn't spend the money or time to convert from my AE101 C52 to the six speed AE111 tranny. Also, those trannies are so hard to get a hold of, especially in the US.

Which power will support the C52 tranny at max?
Cause I'm about to rebuild engine to turbo it and my target is about 200HP to wheels.The question is:
Will the C52 support it?
Will the axles support it?
If not which would be the optimal solution?

Thanks
