6R80 with EEC-IV/EEC-V

[Sevensecondsuv]

Has anyone tried to write code to get an EEC-IV or EEC-V to run a 6R80 trans? Or is the hardware simply lacking enough inputs/outputs?

The 6R80 is an ideal trans and a significant upgrade over a 4R in all the 90s stuff. There's standalone controllers for them, but it'd be nice to have it integrated with the EEC. Just wondering if anyone has tried yet.

no its not possible, simply not enough hardware or ram or rom space

just curious, why would you say the 6r or even the 10r has any advantage over the 4r much less consider it a significant upgrade?

with all 3 trans you only have 3 useable gears for any drag racing situations where your actually making power. The powerglide is only a 2 spd and still out performs all of them.

racing aside for a weekend warrior or cruiser they are all pretty much the same.

Having daily'd all 3 in similar vehicles (mustangs) I have no preference. To me they are all basically the same and I wouldnt prefer any over the other. Then again I would take a manual trans over any of them any day of the week.

Just curious what advantages it has for you specifically?

In stock form 6r would handle at least twice power, more fuel economy and... that's it, I do consider 6r80 a upgrade over the 4r, however im taking what you said. I have driven those 3 and i think the 6r is the best overall and gen 3 mustangs made me fell 10r was a blast

I think your information is slightly biased

Ive ran 900hp through stock 4r borg warner clutches, in fact some of the "built" 4r's use stock clutches.

I would say stock for stock they are pretty similar. The 6r does have a better factory converter but thats about it.

fuel economy is directly proportional to final gearing. There could be some theoretical increase for city only driving but I dont think it would be anything measureable.

Id be interested to know how much people have picked up economy wise when doing 4r to 6r swaps and their type of driving.

I hate the 10R, all it does is shift constantly.

As a daily, I greatly prefer the 6R over the 4R in trucks and think the same benefit would apply to the panthers and earlier trucks. The wider gear spread in the trans allows the axle ratio to be optimized over a wider range of applications. The lower first gear is nice to help heavy vehicles get off the line.
Meanwhile the 10R, at least in factory tune, is just too much of a good thing. The constant shifting and 400 rpm operating band of the engine is super annoying.

I also really like the 8HP ZFs used in CDJR stuff. Ford would have done well to use that instead of investing billions in the 10R.

If I remember right, the first few years of the 6R in the F150 (2008-10ish), there was a trans controller inside the trans that communicated with the Ford EEC, such that the EEC did not do direct control of the trans. In 2011, they went to direct control by the EEC. I've always wondered if those early versions would require fewer inputs and/or RAM, ROM from the EEC. It'd still be CANbus though, so probably no hope of getting it to talk to an EEC-IV

There is merit to both sides... The 10 speed will out perform a 6 or 4 speed in a drag racing situation up to a certain power level. I have driven and raced against both and the 10 speeds versions will absolutely walk the 6 speed versions of same vehicle... However if you start making north of 4 digits the 10 speed starts to lose its benefits. A properly tuned 10 speed is a bad mofo from a performance standpoint. It may not have some of the robustness of a 4r or 6r but it surely can get down the 1/4 mile quicker if done right given same platform. I actually really like the 10 speed in my 2023 f250 as well. It is has much better programming than the 10 speed that was in my 2019 f150. Ford did good with that one.

[decipha]

you can always use a 6r ecu to just control the trans no problem, same as the 4r and 6r people have done for years with 2 ecus.

im not sayibg the 10r is a bad trans but theres little to no benefit swapping from a 4r for the 6 or 10.

What same version vehicles are you referring to ?

I hate the 10R, all it does is shift constantly.

The 10L90 in my CT6 (essentially the same transmission as the 10R) is probably the smoothest shifting transmission I've seen, always seems to be where it needs to be... If the 10R is shifting too much, must be a calibration thing.

[decipha]

x2, the 10r shifts butter smooth and its definetly always where it needs to be, no problem there at all, the same goes for all the trans listed above when tuned properly, never any issues there.

I guess I've yet to find a 2018+ Ford that had the trans tuned correctly then lol. That was 50% of the reason we bought a '23 Grand Cherokee instead of an Explorer. The other 50% was pentastar V6 vs 2.3 ecoboost. And I'm a lifelong Ford man......
