Transmission shifts hard when light comes on

Question

I have a 2004 Saturn L300 the service engine light comes on the picture of the car with the wrench not the check engine light but when the light comes on the car shifts very hard the check engine light just came on and it kicked a code for the tfp I need to know how hard it is to fix that and how much I'm looking at cost at a garage to fix it

Answer 1

The TFP the transmission fluid pressure switch, ? The code is important to have , this does not mean you replace the transmission fluid pressure switch , there is a pressure control solenoid that set TFP related codes
