You may be overworking the engine and transmission. This can lead to premature failure of the transmission. If your transmission keeps 'downshifting' the safe thing to do is to move the shifter so overdrive does not engage. Downshifting happens when the engine has to work harder: like if you are driving fast into a strong wind, going up a hill, speeding up or passing another vehicle. If you are towing a trailer and it keeps downshifting then use the lower gear of you could overheat and damage your transmission. It could also mean that your engine is getting worn out and you have to 'push it' to maintain speed. Some transmissions downshift when the vacuum in the intake manifold isn't great enough to keep the overdrive mechanism engaged. A week engine means you need to 'step on it more' and opening up the intake by stepping on the gas pedal lowers the vacuum in the manifold.

Does a 1997 Geo Metro transmission have overdrive after 35 mph?
If you are speaking of the automatic transmission, no. The 1997 geo metro has a 3 speed automatic. At approximately 35 mph it will shift from 2nd to 3rd gear. This means that it will run at 3500 rpm when traveling at 55 mph. Most cars with overdrive will shift to the 4th gear (overdrive) at this point. A geo metro, which only has 3 gears, does not.
Should you leave the overdrive on your Toyota Camry?
Answer IGNORE THE PREVIOUS ANSWER!!!!! YES, YOU MUST LEAVE THE OVERDRIVE IN THE ON POSITION IN YOUR CAR AND THIS IS WHY: The transmission comes with a total of 4 gears including the Overdrive. Releasing the overdrive only restricts the transmission to a 3 gear transmission and therefore does not give you extra power by turning it on (contrary to popular belief). The manufacture reccomends leaving the Overdrive ON for best fuel econimy and performance. Downshifting to second gear again restricts the transmission to a 2 gear transmission (and is therefore not only 2nd gear) and again downshifting to 1st gear restricts the transmission to only one gear or 1st gear. the previous answer is wrong. L8R. - AHEARS.Not if you want to get the best life out of the engine and transmission. The transmission is set up to shift into overdrive whenever possible, to maximize the E.P.A. fuel ratings. However, this results in the engine revolutions per minute being too low for most driving conditions, which leads to carbon deposits in the cylinders, and excessive unburned fuel having to be processed by the environmental controls system. In city, on in hilly terrain, turn the overdrive off. Cruising on the freeway, turn it on.
