Forscan works for me on my galaxy S9, but it's easier and has more features on the laptop, and my laptop has bluetooth, so I use the same BAFX dongle for both phone and laptop.
Thank you. I also verified that that is the correct shift pattern. I spoke to a mechanic last night, told him the problem and diagnostics, and he said it's the valve body that is worn out because of the soft aluminum used. Basically the fluid is going around a closed valve and causing all sorts of weird shifting and crap.So I just tested it on my way home from work and unless I'm interpreting car gauge pro incorrectly (it's happened before) I am correct on the shift solenoid sequence. have you tried ohming out the solenoid pack? Then ohming out the wire at the PCM with the solenoid pack plugged in? It seems it's only shifting when SSA changes state so SSB could be stuck on or off and not changing state when being commanded.
That's wrong. The trans defaults to fourth gear with no power to the solenoids.I'd have to setup a screen on my phone for it but I can check my shift solenoids as it shifts. I could be mistaken but 2nd should be OFF,OFF as I believe the trans defaults to 2nd with no power to shift solenoids, haven't tried it tho. Usually the sequence is
1st; ON, OFF
2nd; OFF, OFF
3rd; OFF, ON
4th; ON, ON
That is for most older Chevy and ford 4 speed transmissions I've troubleshot in the past. I would suggest just looking at the gear commanded PID instead of the shift solenoids individually. It really does not sound like you have an electrical issue.
