As a brand new 1078 owner, thank you so much! Great information…I have some really hard shifts this is just one of the things I want to run through to try to iron it out. 👍👍
Thank you! When you swapped your gauges did you leave the original sensors in place or replace them with isspro sensors?? Where did you get the shorter oil fill tube instead of the ridiculous oem one?
I went to mechanical gauges for the most part, so no I did not re-use the original sensors except for fuel level. The two trans and engine oil temp gauges are electric and I have new sensors for those. As for the oil fill tube, I fabricated it from the original components. I cut the lower tube that connected to the hose out of the engine flange and ground out all of the original tube metal from the flange with a die grinder. I cut the flared filler end and a part of the first curve and inserted it into the flange and welded it there. I almost messed this one up as I did not measure twice. I almost tilted it so far out that it interferes with the drivers side of the hump… missed it by ~3/4”…
Have an M1081AO that's having shifting issue locking in high gear and won't downshift unless we turn truck off. Changed engine speed sensor and proximity sensor on transmission, still no luck. Could this be the issue in your video?
It could, but if there was an issue with the TPS input the trans control should fall back to using its min and max range RPM inputs to up/downshift. This sounds more like you have a fault and it is locking it in gear… Are you storing any codes in the trans controller? Push up and down arrows at the same time. Display will flash D1 followed by two sets of numbers(eg: 25 12), or two dashes. Write these down and note if the mode light is lit. Press the mode button to step thru the 5 code memory locations D1-D5 and record the codes. - - indicates no stored codes in that memory location. ‘Mode on” in a particular memory location indicates a current/active fault. Once you have recorded all 5 code locations, press and hold mode. After 3 seconds of hold the controller should beep indicating it has cleared all active faults. After 10 seconds it should beep again indicating it has cleared all stored fault codes. Press both arrows again to exit diagnostic mode. Drive the truck and recreate the problem, then enter diagnostic mode again to read the codes again write everything down…
Thanks Ron!
Great information! Thank you for these videos.
Very helpful! Thanks!
Love your videos, you really cover cradle to grave
Thank you, much appreciated. Really enjoy the videos
