Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.

Do you know if there are any trouble codes in it?

Which sensor was changed?

Is it shifting late, or early? Harsh?

Customer: replied 6 years ago.
I dont know if there are any trouble codes the speed control sensor was changed but it is still shifting late and harsh however it does occasionally smooth out.thanks
Expert:  Jerry replied 6 years ago.

The reason I was asking is there is a service bulletin for that particular concern. That will have to do more with the turbine shaft speed sensor. Let me see if I can ppost a copy of it. There is also one on the pump housing

ISSUE

Some vehicles equipped with the CD4E transaxle may exhibit harsh and delayed 1-2/2-3 upshifts along with DTCs for gear ratio errors after the Transaxle or Turbine Shaft Speed sensor (TSS) have been replaced. DTCs may include OBD1 codes 628, 642, 645, 646, 647, 648, or OBD II codes P0731, P0732, P0734, P0741, and P1744

ACTION

If the condition occurred after servicing the Transaxle or TSS, refer to the following TSS Selection Chart and select the correct TSS for the vehicle application. Note that each TSS has the Ford engineering part number on it. Also note that there is a TSS kit that includes an instruction sheet, TSS sensor and correct bolt.

SERVICE PROCEDURE

If the condition occurred after replacing the Transaxle or TSS, use the TSS Selection Chart and determine the correct sensor for the vehicle.

1.Remove the existing TSS from the CD4E pump body.

 

2.Reinstall the original TSS sensor, if available, or install the correct TSS as indicated in the Selection Chart.

 

3.Clear all codes and verify repair.

 

4.If the condition still exists, follow normal diagnostics as listed in the appropriate model year Workshop Manual.
