neutral safety switch on 1999 Chrysler Town & Country

where is teh neutral safety switch located?.....I have to wiggle the gear selector until it starts then it will start the rest of the day......half teh people tell me its a transmission problem the other half say no it isnt at it an expensive repair?

Your vehicle is not equipped with a Neutral safety switch. You have a Transmission range Sensor (TRS) located inside of the transmission. The Transmission Range Sensor (TRS) communicates shift lever position to the Transmission Control Module (TCM) as a combination of open and closed switches. This also sends a signal to the Powertrain Control Module (PCM) to engage the starter. Each shift lever position has an assigned combination of switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this information and determines the appropriate transaxle gear position and shift schedule. Have your technician check the wiring connectors at the transmission and TCM before condeming the TRS

OK so there is no neutral safety switch on my chrysler town and country 99 van.......Its either a TCM or a TRS.....If either has to be replaced can you give me an idea of how expensive a ajob this is>>>>>.I need to know a bit about what to expect when I take it in...I apreciate any type of idea you can give me....thank you
