dabangsta Posted August 8 Report Share Posted August 8 2019 SEL with the 8F35, 90k miles (original fluid, flog me now). A week ago it started shuddering up to 35mph lightly, I setup an appointment to see about getting TSB 21-2081 performed (on my dime since out of warranty). I also bought fluid to change it out. Returned from a 600 mile trip in 115+ weather, no issues on interstate or when exiting to surface streets to home. Back into driveway and push Start button and get message park not available. So it set the park brake and the shifter light was blinking in Park. I tried moving it, and it took a second to engage forward, was able to drive it way, but a few blocks away or started doing harsh shifts, and free wheeling. So it has sat until today. Pulled codes: p0771 - shift solenoid E performance/Stuck Off p2704:00-6c - transmission friction element E apply time range/performance P07e4:00-28 - unable to engage park p0771:00-64 - shift solenoid E performance/Stuck Off p073d:00-68 - unable to engage neutral It will now shift to park and neutral, I haven't driven it enough after sitting to see if it is okay now. I have 5 quarts of Mercon ULV, and I can erase the adaptive tables, but am I just pouring fluid into a done transmission? I can only find a TSB for the 8F35 and Transit Connects and these codes, and seems specific to that vehicle, but is a rebuild/replacement of output planetary carrier and assorted parts. 2 Quote Link to comment Share on other sites More sharing options...
Haz Posted August 8 Report Share Posted August 8 From the 2019 Edge Workshop Manual... DTC P0771, E clutch Does Not Apply symptom, REFER to: E Clutch (307-01A Automatic Transmission - 8-Speed Automatic Transmission – 8F35/8F40, Diagnosis and Testing) If either DTC P0771 or P0772 are set resolve them first. Otherwise, for DTC P2704, REFER to: E Clutch (307-01A Automatic Transmission - 8-Speed Automatic Transmission – 8F35/8F40, Diagnosis and Testing). The above-mentioned diagnostic procedures are attached below as PDF documents. If your efforts progress to you needing electrical circuit & connector detail, I can provide that information. If you elect to clear the DTCs and the Transmission Adaptive Tables, the Adaptive Learning Drive Cycle procedure is attached below... Good luck!

dabangsta Posted August 10 Author Report Share Posted August 10 Thank you for those! A lot of good information that help me at least start narrowing it down, and to do the fluid change. Unfortunately the second step on most is removal, followed by overhaul. I didn't realize that Mercon ULV is $20 a quart locally. Sure with the shipping from RockAuto it was around $10 a quart, but whoa. It is $9 at the dealer, but they don't seem to have any stock on hand.

dabangsta Posted August 10 Author Report Share Posted August 10 Got it drained a couple of times, the fluid was dark but didn't smell burnt, and filtered it through a coffee filter and no chunks. Getting a variety of error still, and a variety of driving issues: delayed shift to D, with a jerk, but can run it up through all the gears and down shift on throttle application eventually I appear to lose 5-8 (clutch E), it still tries, but free wheels until I slow down once I go forward, then reverse complains, and the shifter moves itself to Park with a shifter fault in Park it wouldn't rev up, I think it thought it was still in reverse codes for fun: P0752 - shift solenoid A stuck on P270:00-2C friction element A range/performance same p0274:00-28 friction element E range/performance one for friction element F Looks like it is going on the hook to the dealer, then sometime this decade they will do a diagnostic on it, and let me know I need a new transmission and torque converter. There was a little more gunk around the vent than I expected for a 5 year old 90k mile vehicle, I drained 4.75 quarts, put in 5.25 and probably .25 quarts oozed out the sight hole once up to temperature. I don't think it is was or is high or low on fluid, the old fluid didn't smell burnt or have solids in it (very light swirls of floating something). I don't think one more fluid change will do anything, and no external sensors that I can do anything with related. I fought that extension for the vent putting it back on, while I get the saying "doing the same thing again and again expecting a different outcome" I kept trying to do the the same thing (hose clamp pliers low to compress, grab with needle nose up high, try to get in place and press down before slipping out). I finally found slightly larger needle nose with good grip and popped it right on. On my 6f35 vehicles I had to take off the tire to get to the sight hole, but this one I didn't, I could turn the wheel to the passenger side and get right in there. Also neither plug (drain or sight) required more than my 1/4 drive plastic harbor freight ratchet, I tried them since I had them out already, and easy off. My other vehicles took a 3/8 drive and with all the extensions, holding the center of the ratchet, so that was nice (neither of them leaked, it wasn't low of fluid).

dabangsta Posted August 27 Author Report Share Posted August 27 Couldn't get it in for 10 days: They said it would be 2-14 days for a diagnostic (but it was driven 10 miles last night, parked at a different place, then driven today, triggering even more FordPass Powertrain faults). The transmission shops are probably similar in price for the transmission and installation, maybe by my estimate $500 less, which is a lot, but percentage wise not enough. None of them have really dealt with the 8f35 yet, and hope it is similar enough to the 6f35...not confidence inspiring. Quote Link to comment Share on other sites More sharing options...
dabangsta Posted August 27 Author Report Share Posted August 27 They are saying bearing wear. I suppose it is the planetary gear bearing, same failure that the Transit Connect had? Do I roll the dice and have them dig into it and try to replace that part? Looks like $3000 in labor just to R&R it, but is $500 worth of parts plus more labor worth the gamble? "my lucky day" they have one in stock and can get to it in 2 days. Quote Link to comment Share on other sites More sharing options...
