windstar transmission- RPM sensor

[wackysci]

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-!

It sounds to me like it would be a faulty VSS. This could cause the computer to not know the speed of the vehicle and doesn't provide enough transmission pressure. The computer would also not know what gear to shift into due to the VSS malfunctioning. Don't quote me on this.
