I've been looking in to this swap since i ordered my Sky Red Line heres what i found:
Base 2.4 L LE5 I4 177 hp 170 ft·lbf
Red Line 2.0 L LNF I4 260 hp 260 ft·lbf
Both use a 5-speed Aisin AR-5 manual (GM RPO AM5) (Optional 5-speed GM 5L40-E automatic) the same manual Trans as the Canyon, Colorado, H3, Toyota Hilux, Toyota Land Cruiser/Prado, Isuzu Trooper/Bighorn, Suzuki Grand Vitara/Escudo, BMC Levend.
Aisin also makes a RWD 6-speed Manual Transmission the Aisin AY6 found in the Toyota Land Cruiser Prado, Toyota Tundra, Toyota Tacoma, Cadillac CTS, Holden Commodore.
Im have a hard time finding blue prints or specific data, but a person i talked to at Aisin said they are very similar and should be exchangable with little modification. He also mentioned that they have 2 other trans that are similar.
-AH15/AH16 6-speed from the Toyota Dyna, Toyota Coaster, Hino Dutro.
-AZ6 6-speed from the Mazda Miata/MX-5/Roadster, Mazda RX-8, Toyota Altezza/Lexus IS200.
If yall find any more data please share, this should be a doable project. Im also looking into a stroker kit or engine swap from a european LNF series Direct Injected Turbo engine. Ill let you know what i find out.
The Corvette transmission is a rear mount transmission. It won't fit in the Kappa all that well (if at all).
Not sure why you would want it with the 2.4L anyway. It is really just a 5 speed transmission with a second overdrive gear to help it achieve decent highway fuel mileage and avoid a gas guzzler tax. It doesn't have 6 speeds for performance reasons.
Besides, I don't think this car really needs a true 6 speed with the stock engine. It has a pretty flat power curve as it is, and I would think that adding an extra shift would cost you more time to shift then it would gain you in keeping the revs up a little more.
I agree!!!
I get to second too quick as it is!!!
I wouldn't want another gear.

I have thought about putting in the double overdrive six speed to lower my rpms at 70 to save fuel.
So... does the T56 mount up to the 2.4L???

I don't think a Tremec will mount to an Ecotec. Besides being a 6 speed and being able to handle a lot of power and torque it isn't really that great. I had one in my 04 GTO and it was very notchy and clunky and wasn't very enjoyable in the cold eather. The only reason I'd put a T56 in my sol was if I dropped an LSX engine in it.
I know the C6 has a rear trans, but I believe the C5 is mated to the engine.

The C6 & C5 have the same driveline setup. Front engine to a "torque tube"(manual has the clutch at the engine, auto has a flex plate there)then the tranmission in the rear(auto has torque converter here). The transmission(4L60/80e or T-56)does not have a tail shaft, it has 12" splined output shaft that slides in the getrag diff, and is bolt directly together.
The only T-56's that will work in the Kappa's are from the SSR(this is what was in the concept, and the Hot Rod Solstice), the 98+ F-body's, and the GTO's. All will need an adapter ring/new bellhousing.

The Solstice 2.4 does need a 6 speed for sure. At 55MPH my revs are under 2,000 and I get 36.4 miles per gallon on the Highway.
If I bring the car up to 65MPH the revs go up to 2,500+ and I lose about 5 MPG. That's kinda sad.
My 08 Altima CVT 6 speed Automatic easily gets 38 MPG at 65 all day long. That extra gear brings down the revs big time.
G.M. could easily make the Solstice in a 6 speed, and it would help their overall MPG's

Ah, thank you for the clarification Randy!

The only differences I've seen among the GM T-56's are the two overdrives. The Corvette has 5th as a .62ish and 6th it .50, while all the others have 5th as a .76 and 6th as .62. Those numbers may not be spot on...too early in the morning to do the proper research. The T-56 in the Viper's are similar to the Vettes. I have know clue about the T-56 that werte put into the Fords.

+1!!!
If switching this out to a six speed to lower the rpms isn't the way to go... what about the rear gear? 3.73? 3.42?... 3.08... maybe?
I know it'll kill my jack rabbit starts... but gas mileage is more important right now anyway. I think 3.73 would be pretty good because it would give me lower rpms at 65, but wouldn't kill the low end too much.
Opinions?
Toad
Well since I'm not keeping the stock engine it doesn't matter much! and yes you CAN mount a vette trans to a bellhousing, it doesnt matter much to it! You just have to make an adapter and an output housing ...that or use an early C4 trans, or something else... I think I'm going to end up using a highly modified LS1 in mine, but I'll decide that when I get there.
I would love to see this setup. By the way wlecome back again I have not seen you around in ages.

It could be even simpler if we wanted to get a group buy on having a custom ratio for 5th gear made.
Personally, I have been knawing over using a TKO600 when this one fails. I have a friend that powershifts the living hell out of one all the time. He makes 462whp on my dyno and has no less than 400wtrq from 2800-5600rpm. (408sbf in 88stang)
I also will be considering the STS-V 3.42 rear, pending on 1st gear ratios.

Most of that difference in mileage is due to the aerodynamic losses at the higher vehicle speed, not to the higher engine speed.
Six speeds will not necessarily make a difference in fuel mileage at cruise, the important number is the transmission's ratio range. The AR-5 has a first gear ratio of 3.75 and a fifth of 0.73 for a range of 5.14. The T-56 has gearsets that offer a 2.97 first and 0.62 sixth or a 2.66 first and 0.50 sixth. The ratio ranges are 4.79 and 5.32 respectively. What do all the numbers mean ? It means that, in terms of improved fuel mileage, one version of the T-56 could help, but that the other would hurt. There may be some advantage during acceleration and at intermediate speeds, but neither of those is easily quantifiable.
First, if we want to keep the overall drivetrain ratio fairly close in first gear we would have to change the final drive to 5.5:1. I personally think that the 3.91 in the 2.4 is too low, and that the 3.73 that is in the turbo car would be more appropriate. Even if we wanted to use the equivalent of the 3.73 we would still have to change the final drive ratio to 5.3:1.
If we assume that 65 MPH occurs at 2500 RPM with the stock drivetrain, changing the final drive from 3.91 to 3.73 would drop it to 2385 for a 4.5% decrease. At equivalent first gear ratios, the T-56 would drop 65MPH to 2415 RPM for only a 3.4% decrease. Not much benefit from something that is more expensive and heavier, especially as the weight penalty is likely to cost fuel mileage.
There may be advantages to a 6-speed over a 5-speed, but fuel economy is not necessarily it. And since the 5-speed Solstice outperforms the 6-speed Miata, maybe performance isn't it either.
