Sorry I hate to make another thread about this but I feel I did a fair share of searching.
Randomly gets OD light on off. Past two weeks its been VERY spastic and not repeatability.
codes came up 23 29 56
I know the trans was not too hot in my 1 mile drive and this is the first and last time i ever got this error (56)
When I got the truck it would hunt for a gear, shift hard, buck like a bronco (no pun intended) and be nasty to drive randomly, too. Well I threw parts at it. NEW VSS, TACH sender, TPS, PSOM, fluid drained. It was great all winter and probably 10-11 months.
I have checked TPS and set to 1.1 went away for a day. checked voltage seems ok.
ohmed the VSS, it was within about 100 ohm of target. not that far off.
THe psom was used but i took it out and looked for caps/thermistors that are shot but all looked good and now split.
At 230xxx mi I hope im not looking at a TC. It drives and shifts smooth still, just kicks out of OD and gives me a light. and then it will just back into it like nothing is wrong. It never gets super hot as I drive short distance to work.
My next steps are
-Try a new VSS because they are cheap.
-Then to start looking into the computer. It looks like its a ground issue or something. Any place these commonly rub through???
The windshield did leak but I recently put some urethane and with the recent rains it was dry.
Video of random strobe light. very random.
