How Do You Reset Transmission Control Module On A 1998 Ford Ranger With A 4r44e

3) No 3rd or 4th gear: If the 2 - 3 shift valve spring is missing, or someone has installed it wrong, you will lose 3rd and 4th gear.

4) No up shifting: This problem can be caused by the solenoid regulator valve being out of position.

5) Slips on the 2 - 3 shift: There are two different issues that can cause this problem. Either the bore in which the intermediate servo pin rides in is worn out, or the spring on the intermediate servo piston is too strong.

6) No reverse: If the transmission has no reverse you most likely have a bad SSA solenoid.

7) Delay going into reverse of a forward gear: Has the valve body been removed recently for any reason? If so, there is a possibility you did not align it correctly with the alignment pins. This will cause an internal leak that will result in a drop in the transmissions line pressure.

No automatic transmission is designed to last forever. The 4R55E is no exception. If you find yourself in the position where you need to replace a 4R55E transmission, I highly recommend you consider replacing it with a re-manufactured transmission over one that has had a simple rebuild.

Like all things mechanical, a transmission will not last forever, regardless of how well you take care of it. If a decision has to be made to replace the transmission, I highly recommend you consider a re-manufactured transmission as your first choice. They differ from a rebuilt transmission in the fact that they are as good as a new transmission at a greatly reduced price and often include modifications and upgrades that make them much more durable. A re-manufactured transmission also comes with a much better warranty: three years compared to 90 days for a rebuilt transmission.
