Hello and welcome to JustAnswer!
Are you saying that you have a P0731 (gear ratio error in first) and a P0715 (input speed sensor error) set?
There won't be any voltage to the input speed sensor.
When you start the engine and take off in first, what happens?
Does it almost immediately bang into second gear and stay there?
Does it shift into second normally?
Does it slip in first or reverse gear?
Does the speedometer always work?
It shift's into second normally and yes it stay's there
It does not slip in first or reverse gear.
The speedometer quit working for a short time once in a while.
