Yes! After this, everything back to normal and engine works good.
I came back from holiday with a damaged sensor two years ago and everything works fine in that moment (except transmission in "accident mode" of course)
No, I think. I never doing a KOER&KOEO tests. But everything works fine and it did not show that something is broken.
I will add a one think. Only on "1" gear I can start driving and braking. On this gear engine and transmission works fine. Only on OD/D/R engine dies after put a gear from P/N at a standstill.
Ok, more good feedback. So the engine doesn't stall if you quickly shift to "N" when stopping. This indicates the torque converter isn't unlocking.
Could be TSS
problem, or maybe you have a speed sensor problem, as the transmission uses it's output to govern up & down shifting & the cruise control & ABS
systems also use it's PID
signal to operate.
SO, are you having any problems with cruise control, or your ABS
system, if you have those options?
If your scan tool can read live data, set it up to monitor the speed sensor as you accelerate from a stop, while driving at various speeds & when coming to a stop, to see if it has any signal hang up, or drop outs, as an unsteady speed sensor signal will confuse the computer on transmission up & down shifting.
On being able to move off & stop in 1st gear without a problem is a good clue but I'm not certain yet what it's trying to tell us!!!
Is the TRS
= Transmission Range Sensor, where it's fastened atop the transmission & where the shift linkage & electrical connector attaches, all fastened properly? No loose bolts, cables, electrical connector, No corrosion on the electrical connector pins or sockets, no bent pins, spread sockets, no loose or damaged wiring to the electrical connector. Are you certain you have it properly adjusted/preset with the locating pin, so it's shift positions are properly indexed so they correctly match the instrument panel shift indicator positions?
Same electrical inspection for the firewall computer electrical connector wiring & pins & sockets.
Same for the body to engine & battery to engine ground straps mentioned in my previous post.
