Need some help with a 4R55E
I am not trying to double post, but hoping that there is a GURU here that can help me out.
Please read this thread https://www.ford-trucks.com/forums/8...ml#post7281291 I have posted in the Ranger forum.
Things I need to ad are.
The truck is OBD II even though it is a 95. I have hooked a scanner to it and there are no transmission cods (scanner is an autoxray 6000).
To me it acts like it gets it’s line presser messed up, is there a presser sensor in the Trans?
I have replaced the overdrive light, it works now, it dose not flash.
Could a bad EPC solenoid cause this? Is there a way to test the epc?
My last question is what about the servo seals? The low reverse servo looked good when I had it apart. Could a bad intermediate or drive servo cause this?
Also dos anyone know or have a schematic and wiring diagram for this truck/trans? I want to check the grounds and ohm the wiring.
Tank you for your time.
