mat in tn Posted March 24 Share Posted March 24 I can't help you there, I rebuild my own transmissions. unfortunately, I think this hassle is going to be what you are up against, and I cannot say that I don't understand both sides. being that you are using a "non-standard" ecu/trans controller. especially if it is one which can be adjusted differently than the ford version. not that I have any problem with aftermarket controllers, I have used them. the issue is getting into warranties. I'm not familiar with the diesels specifically or how they communicate with the trans controller so I would defer to calling bauman or hgm and talk with them about your specifics. then you may be at the point of having your trans rebuilt.

I am considering rebuilding transmission myself also, but my dad has really pushed pursuing an option that includes a warranty. So, I’m vetting that out. I am concerned about reinstalling a transmission that big. I had enough trouble when I installed a C4 transmission on my ‘71 F100 years ago. I’ve watched rebuild videos on E4OD tear down, but have yet to watch videos on rebuild. Thanks for responses everyone. I’ll continue to research and consider options.

I don't do e40ds "yet". they intrigue me but I'm busy. they are a very involved trans from what I have studied. they are probably the best for your application though. aside from a c6. now if you were wanting a more affordable path, the c6 may be the ticket.

Mat, the earlier (pre-Powerstroke) Diesels used a transmission controller, it used an rpm signal and Fuel Injection Pump Lever sensor (throttle position) to tell it when to shift. Basically same thing the Baumann and other aftermarket units do. With the introduction of the Powerstroke, it's all in the PCM, just like a gas engine.

As was recommended here, I went with standalone controller from US Shift company (aka Bauman). Still couldn’t get it to work, so had it towed to diesel shop. Mechanic said I needed neutral safety switch wiring from previous C6 transmission. I didn’t have that and neither did previous owner. So, he went with plan B and wired it up at the steering column. It worked well. For a couple days. lol Then transmission decided not to move forward any longer. But, that’s a bad transmission issue, imo, that I need to resolve… not a controller issue. When I drained fluid, it wasn’t even red and there were metal flakes in pan. Transmission guy said it was not an issue that happened in the couple of days I had it running. It was a pre-existing issue. Link to comment Share on other sites More sharing options...

It was a pre-existing issue. this sounds like a possible misunderstanding. if the truck had no means of telling the trans when to shift, with the correct pressure, even temp. then it would not do more than first gear for a few minutes before spinning the clutches and burning through the friction materials to the point of having steel on steel slipping (giving the fluid a metallic shimmer). a c6 needs no info as it is wholly hydraulic. so, it stands to reason that it had no means of being told before you added the controller. I certainly would expect a trans specialist to know this, especially today when the vast majority are controlled electronically. but if at any time before or since you got it, it was attempted to be driven without a controller then it was damaged. it matters not by whom. it now needs a rebuild/reman.

Mostly, yes. Guy I bought it from thought it was stuck in limp mode. Guy he bought it from largely used electrical system from donor truck to power transmission. Resulting behavior was that in drive it was stuck in 4th gear, then 2 and 1 could be manually shifted to. So, I inherited a mess, but I’m trying to correct course and learn along the way. This forum has been a GREAT resource (even if I don’t fully understand it all)! lol Link to comment Share on other sites More sharing options...

I don’t even know that the limp mode was an accurate assessment. He took on truck, thinking he could fix it. Quickly determined it was above his head. I don’t know if a swap from C6 to E4OD will work without a standalone controller of some sort. Link to comment Share on other sites More sharing options...
