Verify that the original solenoids are the same resistance as their replacements.
Well the problem with that is I pitched the originals in the trash already (something I normally never do but just my luck I did it the one time I shouldn't have) so I can't really verify that. I do know the new ones cane from Napa and "are for my 94 4L80E"... With that being said though you very well could be right that I have the wrong solenoids. I say this because I also got my torque converter clutch PWM Solenoid from them for a 94 17 bolt pan 4L80E... It was the wrong one, and their computer didn't even show the right one I needed. I had to go to O'Reilly to get it.
