2v quest for power

Am I the only person on the planet NOT on the T56 bandwagon?

It's just a 5 speed with two overdrive gears. That's it. You do not get another useable gear between 1st and the direct drive (1:1) gear, which is still 4th gear.

I would rather have a Richmond 6 speed. It only has one OD gear, making its 1:1 direct drive 5th gear, and it's not as heavily rated for torque as the T56, but if it's going in a Ford you don't ever have to worry about reaching any transmissions' max torque rating, so that's a non-issue.

Oh, don't mind that, I'm just stirring the pot with that comment.

The rest is valid, though. The T56 is just a 5 speed with an extra OD gear. The Richmond isn't rated for as much torque as a TR6060 (T56 "magnum"), but it really is a non-issue unless you are pushing stupid power (regardless of who makes the powerplant). People have taken the ROD 6 well past its advertised torque rating with no ill-effects.

I'm not saying that the Richmond is "better" than a T56, per-say. I am simply bringing it up as an alternative.

I am on a quest to find out all I can as far as 6 speed options go. So far, the outlook is bleak, at best. The three options I have found that will handle performance based V8 powa are;
T56 (if you actually consider it a 6 speed),
Richmond ROD6,
and Getrag V160/V161.

The Getrag V16x is found in twin turbo Supras and some BMW's, and would definitely do better behind a high revving 302 rather than a 400" 351-based stroker, as its gears are meant to facilitate higher rpm's.

For the record, I wasn't trying to be a keyboard warrior, I was genuinely interested.

However, from what I read that you posted I didn't know that was the case with the T-56, which I was considering purchasing down the road due to wanting the extra highway gear.

I had just taken the T56 as THE transmission of choice for performance. I had heard it was double overdrive, but didn't put any thought into it... until recently.

Now, after some research, and a lot of time spent on some pro-touring oriented forums, I am hearing the downfalls of the T56.

Like 6th gear, the second OD gear, is useless/powerless unless you have really low gears out back.

And, especially for the price, I just cannot get behind a six speed that has the direct drive gear in the same location as a five speed. You literally do not get an extra working gear going from a five speed to the "six speed" T56. I feel like I am being robbed.

And the worst part is that there are companies making different gear sets for the T56, but they all retain the 4th gear located direct drive, and two overdrive gears. Lame.

I don't want to rev the piss out of my motor, I don't want to have extra low rear gears, I don't want to spend thousands of dollars on a transmission that requires compromises elsewhere to be considered optimal.

I won't lie, I'm a little butt-hurt. I used to not have to think twice about what transmission to use, and now I have to find a six speed that isn't a five speed with two OD gears, and still is robust enough to abuse. Or, settle for a bad@ss faceplated 5 speed.

The Getrag V160 is probably one of the strongest 6pds but damn the 4-6k price tags for the used ones are nuts!

Going auto though will be consistent and much cheaper though if you are making enough power to take advantage of it.

The funny thing is that the V16x is only rated for 400ft/lbs of torque, but they sure do hold up to some crazy 2jz action. They are geared towards those high revving motors, and probably wouldn't be too great on an American V8 unless it was purpose built to rev.

T56 is still a good tranny, sure there is better. But I have been driving the mustang around a bunch and for a guy with a fake femur and knee joint, it gets pretty sore and isn't good wear and tear. So I'm going to go with a 4r70 with man valve body and all that good stuff. Eventually...

That's one of the huge things I am realizing in my research. No other six speed shifts like the T56. Tremec apparently nailed it with their gear synchronization in the T56.

The Richmond ROD6 has external shift linkage, and shifts like a tractor (or so some say, others say it shifts just fine).

The T56 is a fine transmission, and the TR6060 would be an obvious choice if I wasn't being picky. But for $3-4000+, I think being picky is allowed.

Tranny is making noise now, so auto might be coming sooner than later.

The nitrous is fun, so might build the rear end and get a good tranny before boosting it

I'll just pull a 4r70 from pull and pay and run the piss out of it till I need to build it. Those are some stout trannys and have o/d

My plan is to have a set and rebuild them as needed. they are affordable to rebuild yourself and it doesn't look insanely complicated... I know I'll blow one

In my opinion its the 4r, like said before not expensive and seems do-able for a home mechanic. They are rated to almost 500ft pounds or something.

I think I can pull one for like 150 at a local pull n pay
