Help ! One day my cruise stopped working ,replaced v.s.s. on transmission today no luck fixing it . Any more Ideas ?

 

I can't tell you what's wrong but there are the switches in the steering wheel, the wiring down the column, the control amplifier and the vacuum operated servo motor and of course fuses.
If the vss were faulty, the engine would have problems also because the PCM uses the vss signal for other functions.
You need service info to work on it unless you get lucky.
