Hello and thank you for using Just AnswerI'm Paul and I will help you with your Question
this is most often caused by a bad throttle position sensor
this could cause both high idle and transmission shifting issue

let me know if you need more help
the part is 30 dollars and .5 hours labor to install
so total job would run like 90 dollars for the TPS.
normal idle speed once its warm would be near 800 its controlled by the computer and is not adjustable
I would not be overly concerned with the transmission bumbing until you replace the TPS to correct the idle speed
it can cause the trans to shift eratically .
no Problem Steve
thank you for using Just Answer
let me know how you make out
no programming is needed for the new TPS
as long as you have no engine light you are ok.
if there is an engine light you can get codes cleared at an autoparts store for free
