I wish I could help you Chuck. I've never run into that problem before. The only "variable" solenoids I know of are for the torque converter clutch and electronic pressure control. The 95-97 trucks had an on/off TCC solenoid while the Super Duty trucks had a pulse width modulated TCC apply solenoid. I wasn't aware of any differences in the EPC solenoid valve.

I would assume if the difference is due to the TCC solenoid, then you would want the one that IS NOT variable.
