ScionFred, how does your car do as far as traction? I might look into boost in the future on my AT

Traction is very good with the AT. I usually leave the traction control enabled but found that disabling it gained a tenth or two at the strip. Out of 9 runs I only broke loose once and that was with 35 psi in the front tires. After that run I lowered tire pressure to 25 psi and didn't smoke the tires off the line again.

Sounds like a lot of time and money for a small improvement. My co-worker has a 08 VW R32 with the 6 spd DSG and I still beat him in 0-60 and 1/4 mile with a 4 spd auto.

It may not be ultimately worth it, but if the sixth gear is reasonably taller than the current manual's fifth gear, that would be nice! The fifth is a bit low for highway cruising with a 2.4L engine. Your auto's fourth gear is an easily better overdrive.

The extra gear would be very nice to have. I'm just questioning the cost-benefit ratio. $4000-5000 will buy you a turbo kit or a 5 to 6 spd swap. I know which mod I'd do first.

The only way it could be feasible is via a junkyard source, and even then it might not be worth it, but it sure would be nice to have a taller top gear !

You're welcome. Sorry to rain on the parade but as cool as this 6 spd swap is, it's also very expensive for the average Scion owner. I suspect that an XB conversion would cost a bit more and know that any AT to MT swap will cost more (new ECU, clutch pedal, master and slave cyl's, etc.).

So, you're saying (for example) the six speed requires an ACT clutch? That should be a performance mod, not basic install. Looks to me like that recipe is designed specifically for performance and is therefore inflated (to be expected with a performance shop behind it). However, even a bare bones conversion may still be too expensive for someone just wanting a taller top gear.

You're right! I found another TC clutch kit for only $300. That brings the cost down to a very affordable $3800 + shipping and installation. Maybe you could re-use the clutch from the used 6 spd and save another $300. Only $3500 + shipping and installation. Now that's a deal!

Sarcasm, sarcasm -- given it'd be going into an xB2 and not a performance build, perhaps many existing xB2 parts would work. Can't easily get around the cost of the transmission of course, but what would a real junkyard price be? The tC2 hasn't been out all that long, but what other cars use that same transmission?

Just went through the swap thread and pulled the posts that seemed most informative (Cliff Notes version ). Doesn't seem likely they'll do it for the xB2, appears the usual deal where forum guys talk things up and then lose interest. Would be interesting to know what the axle associated mods are and exactly why it's necessary to change the entire shift linkage (including cage).

Also the flywheel is the same according to toyodiy both list the identical part numbers.

Remember just cause the part number is different doesn't mean the part is physically different (sometimes it is and sometimes it isn't), manufactures change part numbers for various reasons. Have you physically witnessed the different parts?

Not only are the transmission mounts custom, I was informed that they had to modify the motor mounts and the axles are modified. You can't just use stock ones or others you buy. They will have to sent out for fabrication.

That is cheap for a transmission, was that for the 5speed or 6 speed cuz my old 5speed is $3,500 new from Toyota.

I was hitting 35mpg the way home which I plan on improving even more.

Will be hitting y'all up for brakes and wheels very soon.

Still haven't made up my mind if I wanted to add anymore power but I do want those brakes. I will try and give y'all a call this week and put in my order for them.

As for the shifter cage for the 6speed, it dropped right in using the old mounting points from the 5 speed. Now keep in mind I still haven't installed my console but so far there has been no modification and I don't anticipate any.

I will try and post some photos of the finished product in my tc but please keep in mind its all mounted and you really wont be able to see a whole lot except for the new mounting brackets and six speed shifter cage. You might have better luck looking back on page 12 when photos of the engine/transmission were out of the car.

If the engine were tuned it can't exceed that rpm. I know of a NA tc that was tuned and was reaching 7800rpm.

Just one more thing to add to the list, a new engine tune.

Hmm, sixth gear, 70 mph @2800 rpm....in my auto, I hit 80mph @3k rpm....Think I'll stick with my slushbox and worry about putting a hairdryer on it until the new tc's become "older" and I can find a junked one to take the tranny out of for cheap. I could never justify spending on a TRANSMISSION, what I spent on the car. 0_o

When you figure out how to swap a 6 spd into a XB2 for a cost that can be recovered by fuel expense savings in under 300,000 miles burning $4/gal gas, let me know. I may become interested.
