ISSUE:
Some vehicles may experience excessive torque converter slippage, torque converter not engaging, or Diagnostic Trouble Code (DTC) 628 or P0714 stored in memory. This may be caused by damage to the fluid pump support seal and/or to the groove on the pump where the seal is located.
ACTION:
Inspect the fluid pump seal for damage. Refer to the following Service Procedure for details.
SERVICE PROCEDURE:
1. Follow normal diagnostic procedures as listed in the appropriate Service Manual.
2. Inspect the fluid pump support for damage. If damaged, also inspect the fluid pump support seal groove on the pump.
3. If the groove is damaged, replace the pump.
4. If the groove is not damaged, replace the fluid pump support seal with a redesigned Seal (F77Z-7L323-AA). Refer to Figure 1.
5. Do not replace the torque converter unless it is damaged or fails the criteria listed in the appropriate Service Manual and/or refer to TSB 96-26-12.
This is something I recommend having a Ford Dealer do since they have the experience with the job.
The overdrive off light flashing - indicates a malfunction has been detected
The overdrive off light will flash in your gauge cluster when a malfunction has been detected by the powertrain control module
When the overdrive off light is blinking that means a malfunction has been detected
A malfunction has been detected , could be a sensor
As long as the O/D OFF light is NOT FLASHING there isn't a problem The O/D OFF light just indicates that the overdrive ( 4th gear ) has been shut off . Press the switch on the end of your transmission gear selector ( P R N etcetera ) to allow the overdrive ( or if the Explorer engine is shut off the next time it is started the overdrive will be allowed , that is the normal position )
The transmission has set a code and you need to get it checked.
The OD Light flashing means that there has been a loss of pull in one of the clutches it is more than likely the overdrive clutch, Don't push the transmission much while in OD our you might blow the clutch out. Get it fixed soon before you lose one of your clutches.
Push the button on the end of the gear selector lever ( P R N etc ) The O/D OFF light will come on in your gauge cluster If you push the button again , it will allow overdrive If the Explorer is shut off , and then restarted , overdrive is normally allowed
On a 1995 Ford Explorer : Overdrive is the normally allowed position Only if you switch overdrive off with the transmission control switch on the end of your gear selector lever ( P R N etcetera ) will you see the O/D OFF light lit up in your gauge cluster My 1995 Ford Explorer XLT has to be travelling around 50 MPH before it shifts into overdrive ( but I have the trailer towing package with 3.73 gears )
what does the flashing tranmission light mean on a 1995 Isuzu trooper mean
On a 1995 Ford Explorer : Overdrive is the normally allowed position If you don't want the transmission to use overdrive ( such as when towing something , or if you are driving in hilly country where you notice the transmission is constantly shifting from overdrive to drive ) push the button on the end of your gear shift lever and the ( O/D OFF light should be lit up in your dash )
I had the same problem with my 1995 explorer xls. And everyone told me I needed a new transmission. I got on the Internet and found a solution. When Your overdrive light flashes. You need to see if your tranny has a place on the outside to adjust the bands on the inside. This helped mine no more problems. Hope this helps.
