Note: You can also activate the appropriate solenoids by feeding them near 12v [[such as by using a power probe]] on one wire and ground on the other. They should click! Very useful on-car troubleshooting without dropping the pan.
For sure thank you so much i followed your steps and all seems good im starting to think its the pcm since the resistance seems to be within spec although my 3-2 is 22.6 ohms but i checked in a shop manual its within spec
Truck is stuck in limp mode and i was trying to find if it were a solenoid problem, or harness or maybe even pcm. But i find it weird for all these codes to occur at once so maybe bad ground.
Well that was cool. After 40+ years of working on cars, I'm working on my first transmission in a 96 gmc. Just found out how to change the solenoids. This I a good method but with it still in the truck is that connector easy to get to.?
@@OldSchoolNoe thx for reply. i mean how can i access the plug or cable from transmission solenoid without disassembling transmission pan or valve body?
@@farmlandtiger1377 just like in the video, get a "dummy harness connector," disconnect the big transmission connector and plug in your "dummy harness connector." From there you can test the solenoid you want by using the 2 specific color coded wires.
Super useful info. I will get a pig tail from the yard next time i am there. Thanks again OldSchoolNoe...

do you test it shifted in neutral or in park
@@octvio8634 It shouldn't matter, as the circuit is "disconnected" from the transmission

@@octvio8634 what issue are you trying to resolve?

It should be!
where the hell is it? :(
huh?
