How does overdrive work on a Ford Ranger?
Overdrive means that the output shaft of the transmission (connected to the driveshaft) is turning faster than the input shaft (connected to the engine crankshaft). This gives you better fuel economy.
What does overdrive do in Fords?
Overdrive maximizes fuel economy and keeps NVH (noise, vibration, harshness) at a more tolerable level. There are no downsides to having it on. In a manual transmission vehicle, overdrive gears are used naturally as the driver shifts to higher gears at higher speeds.
What does OD mean on Ford Ranger?
Overdrive is the fifth gear of the transmission, the only gear that spins the output shaft faster than the input shaft. The overdrive cancel button on the end of the shifter stalk prevents the transmission from shifting into 5th gear (OD) and also commands engine braking in 4th gear (D).
What does o d off mean in a Ford Ranger?
The flashing O/D OFF light is the transmission’s equivalent of the Check Engine Light. This should be done ASAP. It could be a minor electrical problem or something much more serious. Driving an automatic with a problem could be asking for expensive trouble.
What causes overdrive to flash?
All it means is that the overdrive in your car is off. If your overdrive light is flashing or blinking, you are not going to be able to correct the issue by pushing a button. It means that something is wrong with your car’s transmission – perhaps the range or speed sensors, or the solenoid.
What kind of automatic transmission does a Ford Ranger have?
A4LD – The C3 was modified into the A4LD 4-speed automatic by adding an overdrive gear, which the C3 lacked. This was the first Ford automatic to use an EEC-controlled torque converter lock-up clutch. Electronic shift control for the 3–4 shift was later added, another first, though other gears remained hydraulic.
What are the most common problems with a Ford Ranger?
All solenoids are subject to failure. The two most likely to fail are the transmission pressure control solenoid and the torque converter solenoid. All of the solenoids can be easily checked with an ohm meter. The reading on a good functioning solenoid should be around 20 to 30 ohms.
Why does my Ford Ranger have no reverse?
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?
When was the A4LD replaced in a Ford Ranger?
It was replaced by the 4R44E and 4R55E in 1995. The A4LD is a weak transmission, and is known to fail in offroading (4×4) applications.
