Torqshift vs 4R100

[2004F250XLT]

Whats the reputation on both trannies as far as shifting, reliability, ability to handle extra power, ect, compared to eachother? Just wondering which if the 6.0 or 7.3 got the better trannie for what it is.

torqshift is better, it's 5 speed and has tow/haul mode.

5R110 > 4R100.
Just handles the power better.
But a 4R is still great, but can't handle as much power.

5r is extremely tough, and i've seen them take a bunch of power and abuse stock with no problems. 4r's hate life with anything more than an intake and exhaust. 5R does have 5 gears(technically 6), but still the same final drive as 4r's so no MPG gain there.

Now when you build it AFAIK a 4r/e4 will blow a Torqshift out of the water because they can be built stronger, cheaper, and shift quicker.

There is no comparison. I wouldn't own a 4r. I went out of my way to buy a 6spd when I had a 7.3.

Oh yea, rock the 6 speed behind the 6.0 auto. Final drives in both are the same but NIGHT and day differance behind the deisel motors.

It is a 6 speed.

On a warm engine the shift pattern would be 1, 2, 3, 5, 6
1-2-3-4-6 cold!

Some feel the shifting 5 times leading them to think it is using all 6 gears but one bump is your TQ converter locking.

Cheers,

My 7.3 was a 6 speed stick. Drove an Auto behind the 7.3 - not great!

The 4R100 is not something I would want to own

My father had plenty of old and new body style 7.3's, all were auto and left stock. The shifting felt pretty "mushy" or "half asleep" if i had to describe it, especially in the ones 97 and older. The shifting in my 6.0 is quick and firm. But whats weird are the gear ratios seems evenly spread out on a e40d/4r100, but on my torqshift every gear is all over the place when shifting under full throttle
