Their is a new choice for us coming March of next year, this new McLeod tranny will be made to replace some of the OEM GM, FORD and Chrysler transmission. No cutting, and is rated for over 800lbs torque, McLeod put over a 1000 lbs torque throught this tranny and the only thing they broke was the tranny dyno. They say the tranny will weight in about 75 - 80 lbs a lot lighter than the Tremec's

Actually the gears are helical with synchros. There is a choice with first gear. Either a 2.95 or 2.66 2nd 1.99 3rd 1.34 4th 1.1 5th .63at this moment there are no options for 2nd through 5th gears. We hope to have these units ready for sale at the end of the 1st quarter to beginning of the second quarter.

Ill stick with my 300$ t56. Woerd looking 5 speed, wonder what the shifter looks like or make it work in out cars? Or if it bolts to the T5 bellhousing. Probably comes with one.

I'm still underwhelmed.. If you want a new transmission, get a Magnum T56:

If you can DIY, rebuild a OEM T56..

These top-loader units just seem like a step backward.

YMMV

Different strokes for different folks.

If you can get T56s for $300, start selling them to us.

No Kidding, if I could get a 300.00 T-56 that could handle 800 lbs a torque, there would be no question in what I would be buying

Guest

I wouldn't even care about torque rating. But I am aware of one guy, running a '98-'02 Trans Am, with a chassis-dyno-verified 999 rwtq, through the stock T56 and a 3.42:1-geared 12-bolt axle. So I'm inclined to think that if you baby it, any '94-'02 T56 will survive 800 ft-lbs.

Guest

Besides, I'll give up $400 for the T56, so you can turn a profit.

I was checking with McLeod, some of the boards were stating that this tranny was made in China, but they stated totally manufactured in the USA, retail price for tranny is set at 2295

a t5 will survive a gadzillion horsepower if you baby it. Im sure if that guy gets even a little traction, the trans is gone. Unless its a stock clutch and the clutch goes first.

Looks like a nice unit!!! Got to get on the phone with McCleod and talk with them about that one!!!! March should be just about the time I'll be needing a trans for the '82.

Still like the Magnum T-56 though, that extra gear would sure make for a fun cruizin' gear!!!! G Force also has an upgrade package for the production 6 speeds to make them stand up to big power and shift a bit quicker, too.... Maybe my old Doug Nash can finally go into retirement!!!!

86TA, I agree with you totally, I would never spend that kind of money on a car that makes 1000 hp to baby it. I built my car to scare me, I ran an A Dragster, running 7.14, 198mph in the quarter. If I am going to spend that kind money on a motor, I will buy a good tranny to handle it

572_Rat

I talked to G-Force, to get the T-56 to accept 1000 hp they want 6000.00 for the tranny, they built the tranny for Rockland that they call the Godzilla, I know the motor I will be putting in will produce 800 lbs torque, with the McLeod tranny they have put a 1000 lbs torque through it already, the extra gear is not really a problem for me, with 4.56 gears in the car with the t5, the engine is only revving at 2400 rpm at 70 mph, because of the tall tire I have on the car

Guest

I wasn't going to revisit this, because it's bit off topic, but a couple posts down someone agreed.
This guy couldn't've posted 999 rwtq in fourth on street radials, it was on drag tires. And if traction plus 999 ft-lbs was going to grenade the T56, it can happen on a chassis dyno, not just at the track. The car is street legal, including emissions, and does run nines at the 1/4 mile dragstrip on drag tires. The T56 is stronger than you give it credit for. This guy is using an aluminum flywheel, but is using a twin-disc clutch. The car is nearly 3700 pounds race weight. If you break a T56 with less power, you either got a T56 with a defect, or you can't drive.

Torque is not want breaks a tranny it is shock combined with the torque, like 86ta stated if it hooks up with that torque it will break, rear wheel dyno don't develop shock, because every thing is gradual, launching at the track is a completely different thing. Can you break a tranny on a rear wheel dyno, sure you can, but it is no where as violent as launching a car that hooks up. Tremec itself only rates a T-56 at 450 lbs torque, they have about 20% tolerance so say 550 lbs, that is why they came out with the magnum which is rated at 700lbs torque. When I call Tremec they flat out told me with the torque that I will be making, they recommended none of their transmissions, they said if I was careful the magnum would surfice with no guarantees

I will keep my 300$ T56, thanks guys


But yes, the T56 will take more than you think. Some however, just like cars, one out of 500 hundred is built better than the rest. My T5 lived behind over 500 HP for a long time. So, the T56 behind 1000 FTLBS is on borrowed time when you thunk about it.

My buddy has a 02 TA with a built 427 LSX, stock trans and has never had an issue. But he also has a Moser 12 bolt that supposedly has issues of bolts backing out of the TQ arm, but he has never had any issues with his and never checks it.


550$ worth of parts from thegearbox.org will makes the T56 good for 700+ HP. Or you can spend more and they can be built for 1200 HP or so.
