windstar transmission- RPM sensor

A&Q about 350Z
Q:

I hear you are the smart guys and can help me!

I am not a car person- so beg the language here--One week ago took my 1998 ford windstar in -- told to get new transmission- torque converter out and I was told I was lucky and saved as new planetary bearings had to be replaced also.

Now- the car "reves up" at 50 miles per hour . On interstate would not go over 30 and rpms were at 3.5. The transmission place first said the car drove perfectly but have now found that it does have a problem and also Kills when turning and when applying slight brakes when turning.- this has happened also just this week after they "fixed" the car.



They think it might be the RPM sensor...is this the same as a TRS- a transmission range sensor- or a VSS- vehicle speed sensor shouldn't they have diagnosed this at same time-- or could this have been the entire problem not the $2000 new transmission??

Any advice how to speak their language and get to the real problem-- to get them to refix this all for free under their warranty

- thanks-!

i believe there is no RPM sensor. I would think it is the VSS.

My 98 windstar had this problem with the shifting it was holding the shift to long to about 3000 rpms the ford dealer changed a sensor on the transmission part number . MLP sensor sw 5198 it hooks to the tranmission. does your overdrive light flash @ times but resets with the keys on then off.

just curiousity, check your transmission fluid level. Since they changed the torque convertor, may be they filled it up when they initially installed it, but never added more transmission fluid after it had run for a little...
