Question 1999 honda accord "P0730-incorrect gear ratio"

I have Honda Accord 1999 4 dr LX Auto Transmission with 127k Miles

I have been having an issue with my Transmission several months ago which was giving a Jerk at the stop signal (I mean when reducing the speed and coming to the complete stop). It appears that it having trouble engaging gears.


Since yesterday when I’m in D4, when try to accelerate, only the RPM accelerates, just like the car is in neutral, other times it works Fine. This issue occurs when gear changes automatically from gear 2 to 3. (Between speed 5-20). If I cross 25 speed it works good.

I had check engine light on and I have pulled the codes as below:

P0730 - Incorrect Gear Ratio


I really hope that the entire transmission does not need to be replaced. Hopefully it is a computer issue or something.

Flushed the trans with Honda genuine oil a week ago.

Any advise you can give me is greatly appreciated

Thanks,

Ash

Ash, did you get any response for this? I have the exact same problem for my 99 Accord EX V6 with 100K miles. Thanks you for the response.

The P0730 is actually a shift control issue.

You can try a drain and fill of the trans fluid - PLEASE only use Honda Trans fluid. Next the shift solenoids can be removed and cleaned with brake cleaner. Check that the operate, apply 12v to them and you should hear a nice "click".
