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

 

so other than that, whats the difference? could i swap to a 5r55e? is there a difference in bellhousing or anything?

 

isn't one a 5spd and the other a 4spd?

 

thats what i thought

 

ok heres what i dont get. ive had to deal with the dealership before and they say i have the 5r44e but according to trs, since i have axle code d, its a 5r55E....

im confused

 

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

 

Thanks scotty....Justin chimed in before ya! Other than swapping 'em out and puttin in a manual, I'm not too knowledgable in the slushboxes/scattermatics side of life. lol.

 

thats what i get for leaving it open to awhile and not hitting reply

 

ok kool..... so is there anything transmission that could be swapped in place of the 5r44e??

preferably staying automatic.

 

i think graniteguy did a 700R4 swap, i like those transes. i had one in my S-10 that was built, with a manual valve body, it is a tough trans

 

a chevy transmission? there any info floating around on that?

 

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.

 

hmm....i wonder how feasible that is.

 

it'd be like converting to a manual trans in regards to the PCM and PATS i think.

 

what about the c6?? will that work? that would be better than the 700r4

 

c6 will not bolt up and you will loose overdrive. im sure someone makes an adaptor for it though

 

meh....not too worried about overdrive. but is there anything that WILL bolt up?

 

dont do it! stick to the electronic trans! there are some upgrades you can do to your current trans to make it pretty stout!

 

Go manual! All the cool kids are doin it! lol

Wonder who this guy is talking about?

 

what would be some upgrades one could do to a 5R...? just wondering because I really really hate how mine shifts, it always wants to slip into 5th all the time.. even when going up hill and I cant even tell when the torque converter locks up on it... I want a manual but Im horrible at it and Id prolly go through so many clutches lol


sorry for the jack

 

www.pdpracing.com

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.

 

manual is gay...no thanks. lol

mine does the same crap. pisses me off so bad

thanks. might have to look into that soon.

 

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...
