- Characterizing the PWM values required to turn on each shift solenoid in a 6R80 Ford 6 speed auto transmission. One more step closer to getting the 302/6R80 conversion completed.

Not sure if you ever got your 6R issues fixed but lately I have been able to pair a 6R80 to a BMW M57 diesel engine for a customer in Canada. He made his own adapter plate in his 2011 f150 3.5 EB 4x4. He removed the original engine used a BMW standalone ECU kept the original trans and PCM and I was able to adapt a calibration to operate the transmission alone Via very few sensors. Like Pedal, Crank Signal (RPM), coolant temp, and t-map sensors. The truck has bee a daily driver since December and I was able to get it to operate as if it came with the truck. If you need similar support you can message me any time.
Could you diagnose a issue I'm having with my built 6r80 has park and reverse when you try to go to first it goes to 5th and 6th no 1-4 has new lead Frame still has problem
So could this be the reason why my 2016 Ford F-150 is shifting rough from 3rd to 4th gear?
Hey man you really know your stuff to build a circuit board like that I have a 2011 Ford f150 it won't go over 65 would you suggest replacing the shift solenoids or replacing the whole valve body assembly
Might be easier to do the valve body with new solenoids. Just do it once... 50/50 shot you guess the right part the first time.
Can I change out a solenoid a long as it’s the same number
Do these solenoids rely on pilot pressure from the hydraulic fluid to drive them back and forth? I am testing linear solenoid valves on the car with the pan off, using a TECH2 to turn the solenoids on and off. They aren't really moving, though the resistance is correct. Is that typical or is there varnish preventing them from moving?
Nice use of a Teensy BTW!! We use them in our Tympan Open Source Hearing Aid platform
Another way to put it... Are you seeing the solenoid move on the bench, or just hearing them buzz? I like your idea of pulsing the current. That's built into a lot of pneumatic on/off solenoid driving circuits.
@@Eric-lj8sw i could not see the pintel move when I sent current through them. Just the buzzing(pwm) or clicking(on/off) when driving. I'd like to rig up a way to run trans fluid through them to see the change in flow at different pwm values.
@@olboy1981 thanks, that's helpful. I was about to diagnose the solenoid as bad, but really it needs pressure to move.
Now to find a 2011 Ford Truck and drive around with a scanner to get the factory reading to input into code.
Hey just curious is there any actual difference between all the solenoids for the shifts? I'm not trying to do any swaps I just wanna fix my transmisson
Yes there is. 2 are normally open and 2 are normally closed. I think A and C are NO type.
i have been using arduino uno to drive my 6hp26 and 6r80 for several years now.
Sick! Are you using dx gears? I’m trying to do something similar on another zf6 speed. Or did you write your own setup? Also my tcm uses a 8 ish volt power system for some reason. Did you set yours up to use 14v?
Ah you’re on the mega squirt forum I saw your posts
@@th600mike3 i have 2 different codes and both work great. what is dx gears?
@@turbothis dx gears is a shoot off from megasquirt's mega shift GPIO setup. Runs on a mega 2650. Do you have your code uploaded somewhere? That would be super helpful lmao. I'm so bad at the coding side of things
hi. is it advisable to replace solenoid or buy the whole assembly?
Depends on what issues your having.
@@olboy1981 for this trans all the solenoids are pwm??
My case is the 8 speed zf8hp
I know torque converter and line pressure solenoid are pwm but i dunno of the rest are on off
Do you have an idea?
@@FirstLast-tx3yj since the 8 speed is nearly identical to the 6 speeds id think that are all pwm. The 6r has one thats on/off. You'd need to find a service manual to get that info.
@@olboy1981 can you please send me the wiring diagram between the valve body and arduino along with the code through email?
Or any method you want please...
I am rotating it with an electric motor and want to shift it on the bench
@@FirstLast-tx3yj for the 8 speed or 6?
Don't they have standalones for these trans?
Like US shift sorry lol
Yes they do but I want to drive the transmission from the same box that runs the EFI. I'm using a MS3 system.
@@olboy1981 makes sense, so if I'm correct all I need is an adapter, trans itself, custom drive shaft, mount, and the US shit set up.
Correct, I'll have about $1K once its all done in this swap. Biggest savings it the custom code and hardware mods to the MS3 box.
@@olboy1981 awesome, lmk if I can buy an adapter in the future! Keep up the good work! Posted in the lightning group and they just wanted me to build a e4od lol already got 2 4r70ws
