This could be a serious transmission problem rearing it's ugly head. I'm assuming your transmission is not getting bad signals from the electronic controls. That should generate a trouble code and give you a check engine light in most modern cars.
The transmission is essentially a hydraulic device. A built in pump uses the transmission fluid to slide clutch packs into and out of engagement to shift gears. Shifting problems indicate there is not enough fluid pressure to make the shift. This can be caused by low fluid levels, clogged fluid filters or problems in the control valves. Fluid level you can check. The exact procedure is in your owners manual but for most cars should be done with the engine and transmission well warmed up and running with the transmission in park.

The real problem here is that eventually the overdrive clutch packs will be damaged if you keep driving with them slipping. The clutch packs are deep inside the transmission and require some special tools and a certain amount of skill to replace not to mention the removal of the transmission. So again assuming you don't have a high-tech, electronically controlled transmission, I would take it to a good repair shop or three and get estimates on having it serviced.

Engine light code says gear 4 out of ratio. I was told it was the OD going out. Do I have to replace the entire transmission, or can I just have the OD fixed?


Overdrive is actually inside the torque converter. Look at the transmission control module. Have it tested for proper operation first. There is a solenoid inside the transmission on the valve body that the module operated. Since you didn't get a fail on the solenoid, the OD clutches may be worn enough to slip. No need to replace the entire transmission, just the torque converter.

Ford e-250 transmission problems


My Econoline 250 with 4.2 lost fluid from hose leak, fixed leak everything was normal for 3 days till I drove it on highway. When it went into overdrive lost forward power. Turned off OD and did ok for a while. Lost forward gears slowly, put in fluid, hard to tell when full. Reverse is fine but have to rev up engine to get forward to engage, then everything is fine at lights and such till take out of drive, then have to rev engine to about 2500rpm to engage drive. Help?

Od light on


Hi there,

When you press in the Overdrive (OD) switch, this simply allows your gearbox to use the highest gear (when it needs to). For example, if your transmission has 1,2 & D gears, the OD acts as a 4th gear. This is useful on open roads and will help with economy.

If the OD light remains ON, then you have deactivated the 4th gear. This means the car will change up to 3rd gear only, until you depress the OD switch again.

Deactivating the OD is useful, when you wish to "manually" change down to 3rd gear, to climb a hill, or need better acceleration.

2004 f150 transmission fault light


Sounds like the transmission got overheated. I would not worry if shutting it off and restarting got rid of the fault.

Enjoy your vacation.
