Does anyone know anything about this transmission? :2huh:

I can't find hardly any information as to what it bolts to, if its available.... blah, blah, blah... :D

It's based on the E4OD (4R100) trans, which came from the old C6. Not sure if it would physically fit in the trans tunnel of an MN-12 car, if that's what you had in mind.

Ha, I own a sledge hammer... and have access to a cutting torch... :rofl:

I wasn't really considering it, but rather just wonding if the they had a 5 speed auto that would handle more torque than the 5R55. And based on what those 5R100's are behind and moving... I think they can handle some torque! :beek:

Thanks evereyone for the info. :thumbsup:

I have theorized about putting a C6 in a MN12 and I once mentioned it in a post about using a 351C. Someone here replied with "I put a C6 in mine without beating it with a hammer." So I guess you would have to try the 5R100 to see.

The 4R100 and 5R100 are larger than the C6, because of the added gear(s). The diameter of the main portion behind the bellhousing would be close, but the fat part of it would extend farther back than the C6.

I know the C6 goes, since a few people have installed that in an MN-12 car behind a 385-series big block (429 or 460).


cheers

Why would you want to? This trans has a 3.09 first gear! It's a car, not a dump truck.

And they don't have a torque converter. And YOUR point is?
Wellllll. That may be true for a maximum performance car in the 1/4 mile. But for overall performance (i.e. mpg and top end) a TC combined with a low first gear (3.09) and a high final gear (2.73/3.08/3.27) and you get the best of both worlds. (IMHO). :thumbsup:

I have always been a fan of letting the gear ratios in the transmission do the torque multiplication because the "torque converter" has too many variables that can effect it's performance. Heat, viscosity, torque input, etc.

Now I'm not saying I'm right or wrong, but that is just my opinion. :D

And if you build the engine with enough torque, you don't need no stinkin' TC.... :rofl: :rofl:

Allright then, go ahead and put that big, heavy, power robbing, dump truck trans in and see how it runs. Hey maybe you can pair it with a 5.4 2V too, they should be a good match for each other. :rofl:
 
#16 ·
OK, ye who is the wisest, spit out some number since you obvioulsy know them:

"big"...What are the physical diminsions of it as compared to a 4R70W?
"heavy"...How much more does it weigh over a 4R70W?
"power robbing"...How much more power does it rob vs. a 4R70W?

It's real easy to "say" things, but unless you can present the facts, i.e. numbers, etc. you're just spewing opinion.... and your opinion is just as good as my opinion, thank you very much. :D

So please enlighten this poor, uninformed dumb a$$, because I always like to learn facts. :thumbsup:
 
#17 ·
If you want to learn fact then do some research of your own rather than asking Kris to do the work for you. IMHO
 
#18 ·
Well considering I spent about 3 hours trying to get info on this transmissison (to include calling the dealership!!) yesterday and came up with squat..... that is why I posted this question!!! Or did you miss, "I can't find hardly any information..." in my original post.

Heaven forbid if anyone on here would actually back up their statements with facts.... :leftright

Excuse me for asking!!! :redmad:
 
#19 ·
If you are sincere I apologize but it seemed that you were more interested in taunting KD than getting real info. Lets see where would I start in your shoes...I might call greenleaf and tell them you are interested in purchasing one but need to know the dimensions. They should have them sitting on a pallet easy to measure
 
#20 ·
OK, sorry for "going off". But I ALWAYS search for information before I post. I don't like asking for stuff until I have exhausted all other avenues. :D

And I was only "taunting" KD because he made statements (sort of snide ones at that) but didn't back them up. :leftright

So anyway, the only thing I was able to find was what I posted in that one link. I also found out the the ones for the diesel (5R110W Torqshift ) are having major failure problems. Other than that there's not a lot out there. :D

I wasn't really conteplating putting this in an MN12, but rather just looking for a stronger Ford 5 speed auto in general. :thumbsup:

So anyway, sorry again for going off. :zwall:
 
#21 ·
You may want to consider the 4R100, unless you are really wanting a 5 speed. It'd probably be cheaper than the newer 5R110, and it has a 2.71 first gear.

Or, just throw a t-45 in and be done with it.
 
#22 ·
I already have the T45 sitting in my shop along with an aluminum flywheel, clutch, pedal, driveshaft, et. al. :D

I was just really trying to find information. I knew Ford had transmissions for the diesel trucks, but I didn't know about the 5R100 that would bolt to a modular, just the 5R55S. I would like to drive a 5 speed auto, just to see how it feels. :thumbsup:

There's tons of info on both the 4R100 and 5R110 on thedieselstop.com, but they will be talking about towing and highway mileage. I admit, I was kinda curious about the 4R100, since they seem to be a lot more stout than the finicky 4R70W (there are guys with 1000ft/lb powerstrokes running them); but I didn't really look into it since what I really want is a manual. I like the 4R100 in my excursion.

I really cant imagine a fast 4r100 in anything but a turbo diesel with the boost pegged out. They run 15's in a loaded down duallie [saw that at the track :) ] I agree with the guy who said it's too heavy and sucks too much power.
If anyone finds one behind a smallblock thats actually fast I'd like to see it :tongue:
 
#25 ·
I've been really looking at the 4R100 for my 69 F100 with the 460 (which may end up with a roots blower on it...). It would be nice to have an overdrive so I can drop some decent gears in it but still keep the fuel economy. (I'm getting about 12 mpg with the 2.75's!!! Yes I said 2.75's!!!!) Some 3.50's and an overdrive would be PERFECT for my truck. :D

2nd and 3rd gen lightnings have 4r100's
