Windstar transmission-RPM sensor

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 slight breaking--



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-!
