    Mr. Electrician
    Hello Mark. My name is Richard. I see you on here alot helping people with the E4OD trans. I would like to ask you about my trans in my 97 psd truck. I got a 97 parts truck that had the trans in it. it drove fine and shift great . I pull & put the trans in my truck with new fluid & filter,trans had been rebuilt and was very clean . I felt lucky geting the parts truck. Now the trans pulls fast in reverse after it heats up. When it cool it works great. the trans shifts good into gear and no hard shifts. I did notice pulling that it wants to shift like 1,2,3,3,4,od . I more worried about reverse because it feels like it like a 1/8 thottle when it gear. it move fast in reverse. i Just wondering if there anything i can do about that. Thank you

    would you happen to know where the computer gets its trans temp reading from that is read from the OBD2 port? 2001 supercrew 5.4liter 4wd with the 4r70w unit. (I use a SCT lie wire which has readouts for arious sensors through the OBD2 port.) I am curious as while towing my camper up a steep grade in northern japan while on acation with my family the temp went up to 175 three times for about 2~3 minutes each time.

    I saw some posts that said 220 and aboe were bad but those were measured at the outlet from the TC which is higher. the trans fluid only had 4000 miles on it and now it has a s tinge of that burnt smell you get from old trans fluid. what is a safe temp from the sensor that feeds the OBD2 port?

    Thanks in adance

    Ken Morgan.

    Only put 15k on it since last owner said he replaced the transmission..... but it was probably a high mileage junkyarder he never said... I know i have enough fluid.. my transmission temp never seen about 150 degrees.. Ive pulled 8k trailer with it even now with no problems. 70 percent of the time gear engages just fine. Other times Id have to give it a few seconds or slightly raise rpms just a hair to feel it go into gear and then it rides all day no problem in gear till next time I take it out of D.If you want you can email me vadgru@hotmail.com or call 360 909 5152. Thank you

    Hey reading some forums about 4r100 being slow to engage into drive or when someone needs to rev slightly to get it engaged & after that all drives fine once engaged. So the 2 possible fixs or repairs one can do as far as I understood was to tighten bolts in valvebody that could cause pressure to leak & you mentioned clutch seals. I know how to get to the bolts to tighten and do a flush on transmission with filter while im at it but I cant seem to find any information on clutch seal you mentioned and how Id go about replacing it.. also if theres anything else i should do to trouble shoot the problem.

    That wasn't one of my posts. I don't know how any transmission shift could cause the axle to lock. A really bad trans shift can break the trans, but I don't think it can break the axle.

    I would agree something has broke. Was just curious if you had ran across anything like this. The overdrive light is flashing, but I haven't ran the codes yet and usually the tranny codes don't help much. I had read one of your post talking about the rear axle could lock if one of the transmission shift points didnt go as it should. But I think that was 3-5 shift.

    Hello Mark, Been reading a lot of your post lately and thought you would be the person to ask. A customer brought in his truck "03 f350 6.0psd dually" that had stalled on him and wouldn't start, turned out to be a locked up ac compressor. I replaced it. He drove away and filled up his truck at the gas station, as he was pulling off the rear tires locked up on him like he shifted to park. So he called me and I went out there and tried to drive it, it moved a little then locked up the rear tires again. It went into limp mode and you could hear a "ticking" noise from the torque converter as you revved up the engine to go. We drove it back to my place in limp mode, But after checking it a few more times, not sure it is limp mode because it does same thing in reverse, you have to get up to 3000 rpm just to get truck to budge forwards or backwards. Now it makes like a hydraulic whine noise when trying to move any direction. thought you might have some idea's?

    Mark, howdy from Arizona. Do you happen to know if there is a 4 spd tranny or 3 spd with AOD that will work in my 1979 E 350 RV?

    Alot of people are telling me to contact you. I am currently in the midst of placing an 11 f150 6r80 into a 11 mustang gt that was manual. I have quite a few questions if you would be willing to answer them.

    Am in planning stages for '60 T-bird build. No racer, just street plaything, the car Ford would have built had they the tech. Considering a 5.4L/6R80 from F150, Navigator, or Expy, strong desire to include 6-speed auto in build. RE: trans control--Can I not pull entire system from donor vehicle, computer, and all? Planned swap of steering column from donor for tilt, air bag, conversion to rack & pinion. Will that satisfy anti-theft issues? Also planned electronic gauge package fitted to T-bird dash bezels for speedo. Will change from donor's typical 3.7:1 ratio to 3.01 rear affect shifts? Can computer be reprogrammed or must I match ratios? Are breadth dimensions available for trans? (trans tunnel surgery issues) Understand will require a lot of wiring, but will likely strip T-bird for restoration anyway. Enjoy a good challenge but would like to avoid major software reprogramming if possible. Project do-able or am I missing something?
