I changed the input and output censors in my intrepid, but the speedommeter still goes crazy

Wheel speed or trans turbine speed sensor?

It is located on the left side of the transmission about half way up the body toward the output end. Has a wire clip attatched and looks similar to a coolant sensor. (about 3/4 inch diameter and a couple inches tall)

I recently had that issue with my 99 intrepid. I changed the input and output speed sensors. they cost 130. for both. and now it no longer gets stuck in 2 nd gear and drives more smooth.

The output shaft sensor is where the TCM gets its info. And what the speedometer runs off of. It is best to have a diagnostic ran on this first. But shooting from the hip, I would go for the output sensor.

replace dash cluster

That sensor is located on the transmission near the RH axel. 10mm bolt secures it. It's a 'Hall" sensor. When replacing, remember to reinstall the horse-shoe clip which retains the gear to it.

have it checked for transmission codes before you keep replacing parts

the solenoid pack inside the transmission.

it sounds to me like a bad censor...you would probably have to take it to a shop for them to run a diagnosic test, that should tell you what censor.

All the posts at many other sites suggest changing the input and output speed sensors. About $35 at Autozone.
