Its not the battery or alt. Shifted great for the first 10 min then statred slipping and i drove it home in failsave mode.
I am.happy about one thing i.know its nothing mechanical inside the transmission

I Just poked head under the motor while it was still hot and i cant find any leaks either. One thing i Did find was the the middle hose on the transmission thermostat above the transmission oil cooler was not hot but the other too were...
