Torqueshift Specs?
I was just wondering if someone could post the actual specs for the torqueshift transmission. Stuff like the power and torque capabilities, gvw, gcw ratings, just a general chart. Thanks!!

It's a helluva lot more than the Allison and Dodge's tranny in stock form!! I'm not sure about specifics, but I've read reports that it can handle somewhere around 900 ft.lbs of torque in stock form. Someone will be along shortly to answer with specifics. I just threw in the bit about the Allison because we tried throwing a little more torque at my dad's Allison and it instantly went into limp mode.
IMHO, the TorqueShift is the best tranny in a light duty truck right now!! And I'd love to see somebody prove otherwise!

I don't know the actuals either, but from what I've read, it's called a 5r110 and the 110 means 1100ft-lbs torque. That sounds a bit much, but with all the mods I had on my truck (still listed in sig) I was only running a performance torque converter and it handled everything I could throw at it without going into limp mode.

I do not believe that Ford has ever officially released specifications on the trans. However I have been told the same thing about the 3 number designation after the "R". It is supposed to represent the transmissions maximum torque at the input shaft. 5R110 being 1100 ft. lbs. and the older 4R100 being 1000 ft. lbs. If this is true, the upcoming 6R140 should be a beast.

Mark, where did you get those numbers? I'd always heard the 1100 lb.ft of torque ( It just seemed high), but I'd never heard that it's after the t.c. multiplication. I'm just curious because there are a lot of guys on here running much more than 580 lb.ft of engine torque and they don't have a single problem....myself included.
As for the comparison of the Allison, just remember that GM "owned" Allison and their namebadge. I've yet to meet a real GM guru who will admit that the Allison behind the Duramax is a real Allison tranny. They'll all admit that you'll have to bulk-up the Allison tranny prior to putting any real power to the Duramax motor. In all fairness, it's a good enough tranny if you're running stock power.

The transmission is really a 6-speed
1st = 3.09:1
2nd = 2.20:1
3rd = 1.54:1
4th = 1.09:1
5th = 1.00:1
6th = 0.71:1
The transmission only uses 5 gears at a time depending on engine temperature.

Warm Engine Temps = 1,2,3,5,6

Exceeding that number usually won't break it. The trans was designed to last a lot of miles. Running more torque will probably reduce it's life. Also, unless the truck is only used on a drag strip or truck pull, it won't be running any more torque than stock. It only has more torque when your foot's on the floor.

The information on the Torqueshift i posted is from the Factory Service Manuals. They can be purchased from www.Helminc.com
The feeling you may be getting between 4th & 6th or 5th & 6th is probably the TC locking & unlocking. In Tow Haul mode the TC locks in all gears, locks sooner and stays locked longer, and also provides engine braking in all gears.
