Six Speed in a 6GC Options

[Fastbird]

I've heard talk of people thinking about it but have never seen any factual attempts. These things need a sixth gear.

I was pondering, and it probably wouldn't be toooooooo terribly difficult to have a bell housing adapter made for something like a 7th gen and then have a custom input shaft in a longer length made.

Are there any other ideas floating around out there?

Actually the idea of running larger tires would be the easiest way to do it. With the downside that you increase the overall height of the vehicle, and therefore the center of gravity.

and how do you plan on controlling said tranny

We carry the PCS standalone transmission controller, he could use that. They work really nice, plus they all kinds of cool features, like you can add in paddle shifters, have different shift maps that you can swap between, control the shift harshness based on various factors, etc.

Hi all,

Reco's post regarding the C-ONE is not what I had in mind. The C-ONE conversion for the E153 or E154F will only bring the gear ratios closer together, which is good for racing purposes to keep your RPM in the power-band between gears, but at top gear your RPM will be higher than before the upgrade.

I currently have an A140E mated to my 3S-GTE. It's not known for it's strength, so I've had to set my shiftpoints to occur below 5000RPM on full throttle.

Yes, i purchased a PCS controller to control my transmission. it cost me almost a grand, so it's a bit more than I like. In theory the controller could also control a U660E.

The U660E is from Japan, and has been put in the late model Toyota Aurion and Lexus ES350 here in Australia.

OK, i am "pretty sure" U660E bolts up to the 3S-GTE:

A 3.5 litre 2GR-FE mates to both the U660E in the Aurion and the U151F in the new Highlander (Kluger).
The U151F will mate to the 2GR-FE as well as the 3.3 Litre 3MZ-FE in the old Highlander.
The 3MZ-FE mates to both the U151F and also to the A541E in the Camry.
The A541E is interchangable with the E153.

It is therefore highly likely that the 3SGTE will mate to the U660E. My main concern is actually whether we can create/aquire adequate brackets and mounts to support the trans in the celica engine bay, and also whether the transmission will actually have room to fit inside.
