Error code p0730

[Nhfd01]

Anyone have any experience with this code. Incorrect gear ratio. I have a 2013 jku auto, basically won't shift into 4th goes to limp mode a throws the error. Dealer is saying it's my throttle body? I am thinking trans either a output sensor or solenoid

Did you regear?

Still factory gears

Still factory gears

Ive seen this code before a few times, once it was because the gears programmed into the vehicle (example 5:13) were not the gears installed in the vehicle (example 5:38)

and the other time it was the valve body..

And essentially it would work fine all the way up to 4th and it would go into limp mode.

Their was an issue with the throttle body it now shifts into 4th probably because of the new tps sensor, but new valve body on order. Love warranty. Time to buy a mud toy and keep the jeep on the trails
