Engine Performance problem
1998 Mercury Sable 6 cyl Two Wheel Drive Automatic 167000 miles

I've replaced my speed sensor and now my car is acting up again.I took it to ford and they said it might be what the speed sensor connects to. It is sitting there over night til they find out for sure. I want to know what that part is called and how much I should expect it to cost so I can get a fair pricing.

Depend on finding an estimate should be given
about $100 for diagnose

Check the vehicle harness connectors for proper installation at the Transmission Range (TR) sensor, Turbine Shaft Speed (TSS) sensor, Vehicle Speed Sensor (VSS) and Transaxle Top Connector.
