codes p0734, p0733
P0733 - Gear 3 Incorrect ratio, P0734 - Gear 4 Incorrect ratio.... Possible causes - Low transmission fluid level - Dirty transmission fluid - Shift solenoids - Transmission mechanical problems - Transmission hydraulic control circuit
Thanks for the areas to check out. sorry for the delay, I've been gone. I've already done the fluid drain and change, shifts into 3rd but still no overdrive. I was going measure the control signals from the TCU and ECU..Is there a way to test the solenoids? Visual check? I was told the car will not shift into high gear until the engine temp reaches normal op temp. Could it be a faulty thermostat circuit? Thanks for responding and any information that could help me or better yet, keep me from doing something stupid. I'm a Chevy man, this is my first Kia. I really like it.
