4r55e and 5r55e differences...

this may be a completely dumb question but my engine/trans knowledge is very limited so if its dumb then bring on the hate!

anyway....whats the difference between the 4r55e and the 5r55e? i know on my truck(3.0L) i have the 4r55e. could i run a 5r55e? yes or no and why would be awesome if anyone can help me out!

thanks

on your 3.0 you should have a 5r44e not a 4r55

the 55 and 44 designate the amount of torque the trans is designed to handle

the 4r55 and 5r55 can handle 550lb/ft and the 5r44 and 4r44 can handle 440 lb/ft

anything that starts with a 5 (5r44/5r55) is a 5speed anything that starts with a 4 (4r44/4r55) is a 4spd. all the 44s have 3.0 belhousings and the 55s have 4.0 bellhousings. i dont think you can swap without a 5 speed computer, since the computer controls the shifting, it wouldnt know what to do without the matching pcm to go with the trans

a 5r55e, 5r44e is a 5 speed


a 4r55e is a 4 speed



first number is the amount of gears, the second set it the torque range

Graniteguy did it with his existing manual transmission truck. Had to do nothing in regards to PCM. it's a 3spd + od trans...you can lock out OD too. I dig 'em. If i could afford it, my chevy would have one in it.

sells a complete kit that replaces

the valve body
2 shift kits
replaces some key orings
does a few other things

my trans has been great since then and I am turning 37s! I would have loved to try it with stock tires.

According to the chart on trs it seems anything above a 2001 has a 5r55w but it doesn't specify engines. I am wondering if the 04 3.0 trans I have is a 5r55w?

copied the chart...


C3 V 1983-1984 2WD Ranger 1985-1988 Ranger Without Overdrive 3-Speed 2.47 / 1.47 / 1.00
C5 W 1983-1984 4WD Ranger 2WD & 4WD Bronco II 3-Speed 2.46 / 1.46 / 1.00
A4LD T 1985-1994 Ranger & Bronco II With Overdrive 4-Speed 2.47 / 1.47 / 1.00 / 0.75
4R44E T 1995-2001 4-Cylinder & 3.0L Rangers 4-Speed 2.47 / 1.47 / 1.00 / 0.75
4R55E T 1995-2001 4.0L Rangers 4-Speed 2.47 / 1.47 / 1.00 / 0.75
4R70W U 1996-1997 5.0L Explorer 4-Speed 2.84 / 1.55 / 1.00 / 0.70
5R55E D 1995 - 2001 4.0L Rangers 5-Speed 2.47 / 1.87 / 1.47 / 1.00 / 0.75
5R55W 2002 - Ranger 5-Speed 3.22 / 2.41 / 1.55 / 1.00 / 0.75
