    97 4L80E dropping out of TC lock up

    i know that Americans are notoriously bad in geography... the US isn't big enough to drive 5000 miles in a straight line. from Seattle to Miami is 5500 kilometers, not miles. and my MH fore sure doesn't float. so no, i cant drive it in 3rd home and do it im my shop besides, even if i ship...

    while its almost 30 years old now, my trans is just past 60k miles young, mostly driving by on old guy treating his new RV with soft paws... from what i see, i dont feel that this trans is dead. i do also own a burned Ford AOD, burned by the rip off a tourist trap in Atlantic City that was...

    after todays issue with the MAF i probably order a new one too. i tried 2 from O'Reilly, both over reported by 15-20%, not acdelco though. i probably order one through rockauto. and i add that harness and a filter, and while i change that i check for that broken spring. going to be next week...

    i think it was some sort of knocking, came mostly from bank 2. i think i need to go though my ground points. make sure they are good. i also need to get some needles and alligator clips to back probe the PCM. ive been musing about the health of the PCM too. but then, its up above the...

    97 4L80E dropping out of TC lock up

    im using an UltraGauge, similar to scangauge. i can make the tps inctement at about 0.5% all the way from 0 to 100, no dropouts, no erratic behavior, pretty linear... was a test i did a week ago 😁 also keep in mind i tried with tps unplugged, and the 4th still does drop out with tps unplugged...

    i changed fluids about 2k miles ago. see for yourself, i think i was the fist in there, at least its 20 years and 6k miles old, cause thats what i did drive with it. filter looked like brand new, not dirty at all. i just discovered that my MAF goes bonkers in rain.... i think i have an...

    okay, plaid some more. coolant plug off, -40c in odb, dash showing real temp. no change in Transmission behavior. plug back on. tps plug off, boy what a change. transmission feels like a manual, switching real hard like a double clutch transmission but without the enfine adaptation to it, the...
