has anyone dropped a 6-speed into their celica or if not can you??? if so on either, how much does it cost and where do i find it???

yah, i love to revitalize dead topics, but anywho, isnt the beams altezza engine 6spd......couldnt u use the tranny from that with another 3s series engine??....with the right fabrication i believe it can be done...true i have nothing to back that up, but after reading of ppl doing v6 swaps, supercharged 3sfe
s and many other things, it could be possible right?? or am i jsut talking nonsense??

I think it's all nonsense.Isn't 5 gears enough shifting already? That and the fact you would probably never use the 6th gear.

Celicas werent engineered with 6 gears in mind. Like most sport compacts, 5spd is the staple.
6 spd trannys are suited more for high power 6,8,10,12 super cars. Where 6 gears is necessary.

Ok so it could be done..But..Why?

That makes no sense at all. Look at the S2000, Civic, RSX, 7th Gen Celica, new MR2 (SMT6 tranny), and a handfull of others. All with six speed transmissions (or at least available). It's not a matter of how many times you shift, it's a matter of gearing. With a stock motor (5S or 7A), sure, the Celica needs the steep gearing and final drive ratio as stock to keep it from being too much of a burden to get moving in traffic without impeding others. But, for some of us who do a lot of highway cruising or have upgraded to a 3S-GTE, we don't need that steep gearing. And personally, I HATE driving the celica on the highway for extended periods of time because at 80 MPH, turning 4K rpm's with the custom exhaust droning away is flat out tiring. It would be MUCH nicer to have the same 1-5 gears (or close) with a more overdriven 6th gear for those highway cruising period.

Six speed transmissions aren't just reserved for high power "super cars" like you think. The main reason the six speed came into prominence is the extra overdrive gear for improved fuel economy, be it on a 4, 6, 8, 10, or 12 cylinder engine.

*sigh*

Lemme explain a few things. A LOT of new cars are now coming with 6 speeds and 7 speeds... why? Sporty feel and fuel economy. The issue? Well... those trannies were DESIGNED for those engines... therefore the gearing is perfect (or damn near perfect). This topic talks about 'bolting' up a 6 speed... without any understanding of gearing and how it affects performance. Let me give you a good example of BAD BAD gearing. 7th gen Celica GTS. Potentially a 15 FLAT stock car... yet when mated to an older POORLY geared tranny (stock auto)... the car turns into a 17 second slug. 15 seconds versus 17 seconds is like... 5-7 car lengths. While potentially having a 6th gear can be done correctly... can anyone afford a custom gearset? Who wants to pay up for a custom tranny that's gonna cost almost as much as the car itself?
