I used a BBF lakewood bellhousing with a McLeod adapter plate for my T56 swap.

Default Yep

Lakewood, adapter (now available through McLeod and Forte), hydraulic throwout on mine.

McLeod has a better solution now...talk to Red at McLeod.

would a T56 be feasible in a 3/4 ton truck application with 5th wheel camper pulling duties? Or do I need to stick to a ZF5 if converting to a manual?

Default I wouldn't try it...

The T56 is a very strong transmission, but due to the gear ratios, I wouldn't use it for a hauler unless you were willing to run a very low rear gear. 5 and 6 are very very tall. You would find yourself in 4 all the time unless you tow at 100mph or run 4.56 rear gears.

From a strength perspective, unless you're putting out in excess of 600ft-lbs, I don't think I'd be afraid of using it. I can show you viper footage of cars in the 9's and even 8's running this transmission. Granted, I don't have longevity figures...but seeing they can do this even ONCE is enough to raise an eyebrow.

From a cost perspective, I'd think it'd be cheaper to use a truck gearbox and associated hardware.

From a performance perspective, the T56 shifts a lot nicer, and faster. How much of that you care about, I don't know.

Well, I have a T56 in my other car (C5) and I would like to go manual in the truck someday. The E4OD is very expensive to rebuild, especially if you want it "built" and I would simply prefer a manual as a solution to the anemic E4OD that takes so long to shift.

A better and quicker shifting trans would be a very big plus to me. Like everyone, I want the best of both worlds(performance and economy) and a T56 or even ZF5 seems to be a good way to get there. If I am pulling my 5th wheel, I won't mind driving a little slower (I usually do anyway) and keeping the trans in 4th, basically just using 5th and 6th gear for empty driving. I would love to be cruising empty at 1600rpm doing 70+MPH like I do in my vett too.

I have a built E4OD in my 93 Lightning. It lasted 100K hard miles the first time before rebuilding and I have put about 60,000 hard miles on it since (beating on it at WOT, blower application) and cant say much bad about it. The problem with the shifting behavior is more PCM related (computer) than anything else. Ford has some funny ideas about how an automatic transmission should shift, and about how much TV pressure is needed to keep it alive under tow or race duty. Recalibrate the processor and you would be happy with it. Put a transgo shift kit on it, then recalibrate the processor, and you would be even happier. My truck barks 1, 2, and 3 and shifts faster than any 5spd. It can be done; doesnt take much...just a good calibration job. Find a diablosport dealer near you. But yes, if the trans is already tired, you can spend $5K in a hurry doing this; even before the calibration work. If what you really want is a manual; it'll be cheaper for sure.

You wont break a T56 in 4th gear towing unless you are making an insane amount of torque. It would work just fine provided you gear the truck correctly. And, in a low-load non-tow situation, it would be a hell of a lot more fun than the ZF or the E4OD.

My crystal ball says "The end is near" :cry:

It had a moment or two about two years ago, in very hot temperatures and in stop&go traffic that it began to slip. I quickly added a big trans cooler and some lucas tranmission 'Stop Slip' and have not had the problem since, even pulling the 5th wheel. But I worry that it wont be long before the trans gives up the ghost.

OK, so if considering a T56 for a 90 F250 with 460, which would be the most compatible T56 or does it not really matter??

The 460 is 10 spline right?

Default What I used...

My experience has been that the Viper T56s seem to take a lot more punishment than the aftermarket/mustang T56s. I was told by Tremec that this is due to the input shaft design. I don't know if this is bunk info or not, but I went through the bleeding-edge pain of this type of conversion in hope that it's true. I went with the actual Dodge part.

I have seen some pretty crazy viper power-adder combos hold together...even cars in the 8's, and I had a hand in the design/build of a 750hp viper that hit the cover of Viper magazine...and what we did to that transmission was nothing short of idiot-level abuse for optimizing 0-60 times, etc. We rev'd the engine to 6500 and side-stepped the clutch more times than I can count. On the road course, slam-downshifting into 2nd inducing tire lockup on corner entrance with full race slicks was repeated over and over and over again by the drivers put in the car to optimize the road times. It held up fine and is still fine today.

I have a friend with a blown 408 fox that sheered the input shaft off an aftermarket T56 in 4th gear at WOT on the freeway. 700hp combo. I havn't heard of that happening on the viper unit.

As ByronRACE states, you certainly want to use a Viper spec. You might want to talk to D&D, they have a blueprinted T56 Viper spec with a modified input shaft (length I believe) and adapter plate that will bolt to a Lakewood bellhousing. Bolts up without hassles.

Also I believe the gears and countershaft are different on the Viper spec T56. 2.66:1 first gear.
