I have 2002 Hyundai Accent 1.6L automatic. I have recently had a new transmission put into the car. Since then I have had a problem that no one can figure out.

After maybe 20mins of driving my car will get “stuck” in 3rd gear. If I’m on the highway, the car won’t go into 4th. Or if I start from a light the car will start very slowly and I have to put the gear shifter into 2nd gear. If I stop and restart the car the problem goes away for another 20mins or so. Time varies for day to day.

I have 2 codes that show:

P1529 : Manf cntrl veh speed
P0734 : Gear 4 Ratio Incorrect

I just took the car back to the trans shop and they did a whole trans service, which didn’t seem to help much.

Thanks for any help!

Thanks. Does that mean something is wrong with the transmission the shop gave me? Or is there a different part I can order?

Numbers on original trans MUST match replacement also yr, engine size all need to be same. But would not be paying for a job that is not correct
