Hello, I just got a check engine light with the code p0734 and i have no idea what to do. the dealership want over $200 just to check the problem for me. the code is "P0734 gear 4 incorrect ratio." I cannot find any information on any 4th gens about this topic and i have no clue what to do.
Thank you :(

OD lined little burned if the OD do that tell me
Pump is very good, 4 clutch is good too lined and piston all piston is good when I checked them by the air all lined is good, Converter or TCC was overheating about 7 hours 🤔 after tearing the tranny down I couldn't touch it, valvebody good wiring good 😂, wherever is the problem I can't believe that OD lined does that
