my truck eats trannies,ive got an e4od that previously has been rebuilt 3 times. this time it went out i rebuilt it twice myself and it didnt work right so i took it to a reputable shop that ive dealt with for a long time.the original tranny i took to them got swapped for a diffrent one. when i installed it it drove great for a week then crapped out. took it back(warranty) the tech told me it was his fault he put the newer solenoid pack in it and it smoked the TC amongst otherthings.got it back the second time i couldnt even drive it off my rack smoked the reverse clutches so back out of the truck it came.this process went on another 4 times the TC kept crapping out. i had a torque convertor made for the truck a 3 clutch billet.ive got the tranny back in the truck and have been driving it 3 wks.when i put it in reverse it goes but ive got to hurry and put it in drive if i come to a stop it will kill (acts like wrong gear start in drive)ran my codes no tranny codes.i thought i heard my TC chatter which is usually in indicator i am about to cook a TC(hope i am just hearing things) and by the way the solenoid pack has been changed every time iits come out of the truck,ive had a shift kit put in it,all the upgrades,and had an extra disc put in. my truck is a 92 f350 7.3 idi welding truck. i drive the truck like a grandpa it never does over 60 mph.ive changed the tps and the comp.one thing that has haunted me in the 6 yrs ive owned the truck is code 23 is always present ive set the tps a million times ive had the dealer set it but that code is always present even with new tps. another problem is the brake warning lights. ive got great brakes the lights are always on. when i bought the truck someone dissconnected the abs pump and coupled the brake lines well about 6 months ago the yellow abs light lit up too and stayed on.well i figured it to be a bad abs comp and dissconneted it behind the glove box i figured it couldnt hurt anything cause the pump had already been disconneted. does the tps or the abs tie into the TC circuit
i really need answers i carry thousands of dollars of equipment on this truck and i need to make it dependable

 

Well, I got 193k on mine, and it's still running OK. The E4OD is more complicated than previous trannies, so it's not as easy to rebuild well. If I were you, I'd get one that has been professionally rebuilt and maybe enhanced. There are several reputable places, here is one: http://www.atsdieselperformance.com/...nsmissions.asp

 

There are millions of E4OD's on the road. Someone is doing something wrong if they can't put one together that lasts 150k.

 

My brother in law has a good friend that owns the largest tranny shop in L.A. CA. We got to talking with him about the E4OD and he said if you want a reliable one you need to get at least a model year 95 or later since Ford kept introducing changes until they finally got it right in that year. He also said it helps alot to use synthetic transmission fluid in it. Dont know if any of this helps but I thought Id throw it out for you.

 

ive had all the upgrades put in it .why am i smoking TCs

 

Do you have a temp gauge for the tranny?

The link I posted has some heavy duty componenents, but they are not cheap.

 

no i got a temp stick on the side of the pan,its not running hot ive got the biggest cooler they make installed.i have had the latest TC custom built.the factory TCs are a single clutch non billet.the one i had built is a billet 3 clutch supposed to be bulletproof.dont know what stall speed it is.ive had 3 diffrent trannies in the truck and 8 rebuilds,and 4 TCs. 6 of the rebuilds were done by cottman,ammco,myself,and a local tranny shop. i have rebuilt a few trannies and never had a problem.these e4ods are pure junk.give me a standard anyday

 

I'll take your 96 with an e4od then

Seriously I don't know what your doing to break that many trannies. What do you use your truck for? Hauling, crawling, mudding, daily driver? The only person I know that has broken trannies and what not as much as you abuses the HECK out of his truck, but it pays out decently well for the abuse.

I just have to stand up for the E4OD a bit, it's done ok by me, while I certianly think it's finicky and annoying, i've never had a tranny that doesn't have some kind of problem with it.

Well, I suspect that something may have been missed during those rebuilds, so that's why it is better to buy a complete tranny that has been rebuilt by a knowledgeable shop. Also, the cooling system need to be flushed/replaced, or a filter installed to prevent debris that may have been stuck in the cooler to enter into the new tranny.

In any case, ATS does have a 3 year/150,000 mile warranty, as long as the tranny is installed by an ATS dealer, and it is serviced every 15,000 miles or every year, whichever comes first.

 

two of the trannies were bought already rebuilt from a reputable shop.the truck is a welding rig and i never have abused my truck i never go over 60 in the thing.and its a matter of habit to flush the cooling system on a fresh install.ive got a 94 f450 with a standard and its a friggin mule,super dependable

 

"Welding rig" -- what does this exactly mean? Do you just carry your stuff, or you actually work in there? There was a recent thread about welding causing problems https://www.ford-trucks.com/forums/5...ectronics.html Even if you don't weld your truck, but something very close to it, that may actually cause problems to electronics.

In any case, there's another option, replace the tranny with a manual one, or the whole truck with one that has a MT.

 

I have a 91 302 with the e40d. I rebuilt it myself and put a shift kit in it. It performs better than my dad's 03. You say you had a torque converter custom made? Do you keep using the same one in the tranny's? Another thing, in most shift kits, you are supposed to drill extra holes in the valve body to give it extra fluid. This is very important... Please give us some more info on what exactly the shop calls a "rebuild." I have heard from people that the solenoid body on the e40d's gives a ton of trouble if you dont replace it. Hope this helps

 

the torque convertor gets replaced with the transmisson,yes the valve body was cross drilled,steel planets,45 element sprag,bearing style center support,superior shift kit,e-pak solenoid new pump and a new external cooler and a line flush before install.i replaced everything that connects to the tranny.computer,vss,fipl
aurgathor,my truck is rigged out with all my welding equipment(like a service truck) i own a mobile welding company. i do not weld on the truck.i think my tranny problem comes from code 23 thats been in the truck since i bought it.the fipl is within specs 1.00 idle 3.94 wot.ive got another post in the heavy duty forums about the fipl

 

May be you already mentioned it but what does the whole rig weigh? Could it be too much for the E40D? Maybe an Allision would be better if possible.

 

Is the torque converter you're using a lockup type? If not, then all the slippage could be creating extra heat. Heat is a tranny's worst nightmare(besides water). Also, if you always drive it easy, you may not be giving it enough throttle pressure to make a firm shift, causing slippage in the clutch packs. You say its a welding rig, this would worsen weak shifts, in the superior kits, they have extra springs for firmer shifts. You should use those if you havent, also, it recommends taking every 3rd spring out of the reverse return spring, which also helps prevent slippage.
