Hello. My name is ***** ***** I will be helping you today.
What codes are in the system when the lights come on?
If I had to guess I would guess you got a weak connection on one of the wiring harnesses. Bad connections tend to be worse with temperature.
Its entirely possible. Once you get me the codes I can let you know what to check and also form an opinion on that.
Check fuse 38 in the under hood fuse box both for being good and for having battery voltage with the key on.
Is it good? Does it have voltage on both sides?
Is the fuse good? does it have voltage on both sides?
Are you testing when it is acting up?
Exactly what did you check at the transmission connector?
Did you check to make sure the solenoid pack is getting power?
I thought you said its going into limp mode?
What codes are stored in the transmission control module?
Still? Try clearing the codes and see what comes back. If all of those were active it would still be in limp mode.
Its gonna be an intermittent issue obviously. If you have thoroughly checked the wiring as you said then its gonna come down to a bad solenoid or PCM.. since the solenoids are already new you almost have no other option than to try the PCM and hope for the best. That or wait till it gets bad enough to confirm the issue.
No. Theres no programming or initialization on the solenoids. That is just with some modules (AKA computers). Solenoids just receive commands and open or close based on them.. they dont do any thinking or communicating.
Yes. Using a ford scanner you can command the solenoids through the PCM and then verify at the solenoid connector whether the PCM and wiring are sending out the commands to the solenoids with a voltmeter. But with an intermittent problem like that it is usually tricky to catch it in the act and testing it while its not acting up is fruitless.
And happy new year to you too. Glad to make it through alive as always ;)
