Check fluid level first. See if fluid smells "burnt". The signs are the tranny is dying. Don't go far in this vehicle until you've taken it to a shop you trust. They will pull the drain pan and inspect. Next sign of death will be a whining in the transmission as the suction strainer for the pump becomes clogged with the clutch material. Good Luck.

do the lights come on in the front if its just a little red light its possible you tripped the security on the van . or is it the batery light flashing and the battery is dead

Replace the speed sensor in the rear end.

you need to readjust your cable.

SOURCE: oil pressure fluctuating

The sensor could be failing to read the lower pressure when the engine RPM slows down. Or the pump could be failing. I would replace the sensor and see if that doesn't correct the problem
