Van will move forward, seems to shift OK. When in reverse pump is fighting itself will not move backwards. Put shifter in drive and van moves forward. Each other forward gear pulls when brake is held. Trans oil is transparent with a brown/red tent and swells like it got hot not burnt.
Have remove the battery to access shift solenoids both checked good on top. Have not checked the bottom solenoid on trans yet. Screens in top solenoids are clean and test at 5 Ohms. Anyone have any thoughts on where I should look next troubleshooting? Codes that show up on code reader are PO700 Trans control system, P1750 Clutch pressure control valve malfunction. I am new at forums and threads so please bear with me.

Is the light blinking?
Solenoids can be activated with 12 volts and listen for the click.
