I pull a small skid steer and my truck has a utility bed, truck by it's self weights 7200lbs. Would you recommend a transcommand with a standard e4od. Would it add or hurt the life of the transmission. What to you guys think???

 

I haven't heard good things about it. That why I was asking him how his was working. Guys like a XLT and mike have put shift kits on their E4OD's, as I plan to, with great results. Cheaper too, just a little harder to install.

Shift Improver Kit -

 

Electronic line pressure risers like the banks trans command can cause more problems then they are worth. The E4OD is still very much a hydraulic transmission even though the computer tells it what to to. For that reason, there are practical limits to what rising the line pressure electronically can do to firm up the shifts.

It will work for a while, but it adds more stress to the valve body, seals and certain clutch apply pistons (such as the torque converter lockup piston) which are already weak from the factory, can crack causing a slipping converter clutch (the converter clutch piston is corrected in any decent aftermarket torque converter or more recent ford converters). Certain valves are also prone to side loading wear that can be made worse by elevating the line pressure for long periods of time. This can result in valves snagging in their bores and cause all sorts of undesired results. The main boost valve in the pump is one valve that can be a problem, and whats worse - it can't be removed without pulling the pump which means dropping the transmission.

You can get just as good instant results with a conventional hydraulic shift kit, but with much lower risks of adverse side effects down the road. Shift kit target the specific part of the valve body that's responsible for the mushy shifting and make the change at the source instead of trying to force more pressure in the line from ' higher up'.

If the transmission is a later build date than factory original from the early 90s, then the line pressure risers will not pose as much a risk. Many rebuilders use updated valves that are made of steel to replace the more wear prone anodized aluminum ones. I'm not sure which ones have it and which don't however but the rebuilt valve body I bought a while back had several valves that were steel.

 

As to the quality of E4OD's, I've only had one, and it's currently at 384,000 km, first shift after an overnight park is a little rough, but after that she handles like a champ, towed 8000lb's up a good 12% grade, and smaller trailers up much steeper grades, and never slipped, or refused to shift. Been abused on the trails, deep mud/snow/sand/rocks. Still drives me home. Prolly have her rebuilt at ford at 400,000 - 450,000 km.

 

The one XLT posted states that its a triple disc, anyone know if the BD one i posted is triple disc? Does it really matter?

 

I'd go with at least a dual element clutch considering the power you are going for.

 

i posted that racer X one not because of it's appealing price (well,that's still a lot of green) comparatively to others,but because they are highly spoken of in the PSD section.and you know some of them boys are modded and chipped to push twice,three and even 4 times the power of most of our idi's.
be sure to search racerx over there.higher the price doesn't mean there's a better TC. i highly doubt you'll have any regrets with that one lol.search in the first gen section.......i didn't even try the latter diesel sections.
chances are,whatever is popular and known to be built enough for stout PSD's will live a very long healthy life behind the idi.

 

BTS makes an excellent E4OD... That tranny will cost more and probably be worth more than your truck though.

 

Ok, powerstroke guys like that TC, so do I. Am I correct in thinking that I will lose less HP through the drivetrain with this TC? For example, dyno results would be higher, etc?

 

Hey ya'll, I just talked to the transmission shop guy and he disagrees with putting a triple disc converter in, he said it would make the truck much slower and make the truck perform very badly. He said he would rather have a single disc and have one of the guys in his shop build one for around $700-800.

He also said that a shift kit wouldn't work because the transmission is controlled electronically.

 

Find another shop. This guy is clueless. The converter will not make the truck slower or faster.

The shift kit has nothing to do with the electronics. It improves the mechanical end of he transmission.

 

I am sure this guy ain't stupid, he's been doing it for a long time and he knows his stuff. He said if you have a triple disc converter then the torque converter will lock up way sooner than it should and slow the truck down quite a bit.

 

X2 on find another shop.
im no trans expert myself (trackspeeder is though snapon.fyi)
and your shops info is just all wrong.
for some reason he's confusing high stall TC's or something.
don't put any faith in that tranny shop.
i don't see how he thinks the TC is going to lock up sooner.that is electronically controlled,and like trackspeeder says,the shift kit/valve body alternation is not.
he's all mixed up man lol.
he's probably got something to sell ya.thats why he's selling you poor info.id bet $ he's got an old used stock E40D convertor he's trying to sell ya based on the smack this guy is talking.

 

Converter lock up is controlled by the TCM. Not the converter. A single disk will lock up at the same time as a multi disk converter. The only difference is the holding power of the clutch. A multi disk has more clutch surface than a single disk. More clutch surface will take more abuse. That's why multi disk converters are recommended for extreme work. Towing racing ect.

 

snapon.
ask this guy here what he's running for a convertor:

he's not going to tell ya its a single disk.
