Transmission slipping in all forward. Obd2 codes p0970, p0974, p0977, P0302.
Someone did my repairs on the timing gear, belts, water pump and both cylinders replaced all valves, push rods, lifters etc. On both heads. He also mentioned the solenoid 2, 3 needed replaced. I did not have transmission problems until he did these incomplete work after eight months I ask how much longer it will be? He put the engine back together and returned this to my wife. I drove the car and was misfiring. I checked the codes and these came up. I changed the spark plugs and wires.
All said low fluids, check wiring.
I replaced the fluids three times and fluid is good.
I am trying to replace the re-manufactured valve body that I ordered.
Do you have a video or images on this transmission? It is my fault and loss but, now I am thinking to replace the whole valve body. Any suggestions will be much appreciated.
