Where is the relay for the turn lights of a mercury cougar '99?
"Generally speaking, overdrive (OD) is the highest gear in the transmission. Most automatic transmissions have 3 speeds and overdrive (fourth speed). Overdrive allows the engine to operate at a lower rpm for a given road speed. This allows the vehicle to realize better fuel efficiency, and often quieter operation on the highway. When you switch it on, you allow the transmission to shift into overdrive mode after the certain speed is reached (usually 70+ km/h - 45+ mph) depending on the load). When it is off, the transmission shifting is limited to the lower gears. For normal driving conditions, operation of the overdrive should be enabled only if the average speed is above 70 km/h."
How to attach license plate to a broken plate holder on 92 Jeep?
Overdrive on an automatic is not like the overdrive on a manual vehicle. The overdrive on and automatic is in fact a torque converter lock that stops the torque converter slip that occurs on every "fluid flywheel" until it is locked. This in effect drops engine revs to sustain the same road speed when cruising at pre determined speed set by the manufacturer by locking the outer part of the converter to the part of the converter that takes its drive from the engine drive plate. It is automatically disconnected in normal driving when the conditions dictate and needs no driver input. The OD on off switch is fitted for when the vehicle is towing or climbing hills so the driver can switch it off.More Questions & Answers ...
