There are several red flags that can indicate overdrive is not working on an automatic vehicle. If a car is shifting in and out of gear or out of overdrive is usually the first signal of a problem. Other signals include low fluid levels and and erratic temperature sensor.
The Z24 has overdrive, the base models are 3 speed autos
The people at Ford should be able to tell you
If "OD Off" is lit, then your overdrive is off.
If you have a digital display which tells you the gear the vehicle's in, the gear it's in can tell you if you're in an overdrive gear or not. However, you have to know your transmissions. For example, in a transmission such as the 4L60E or 46RH, only the fourth gear is the overdrive gear, so you know you're in overdrive when you're in that gear. The 6L80E has two overdrive gears, so you're in overdrive when you're in fifth or sixth gear. The other way involved a bit of mathematics, and probably isn't that practical to try doing while the vehicle is in motion. You would also need to know your transmission final drive ratio and your rear end gear ratio.
bad filter and fluid,bad front pump,or the overdrive is going out common problem when using overdrive in the city limits meant for the highway start and always stoping not good to be in overdrive cant stress enough here at the house until she spent $3770.00 dollars dont have to tell her anymore
Overdrive should be ran by electrical ,so check your fuses . If that's not it check wiring that runs to transmission.You will have to get under the vehicle . There is an electrical switch that shifts the trans into overdrive , that is your next step . If you have a owners manual in the glove box it should tell you which fuse runs the overdrive circuit .Hope this helps . Rick
The top gear on the transmission will be marked 'OD' usually. If you have more than a three speed automatic or four speed manual transmission, it's a pretty safe assumption that you do.
700R-4 if it's an overdrive transmission. You can tell if it's a 4 speed overdrive by the "D" on the shift indicator. Overdrives have a circle around the "D". Non-overdrives (3 speed automatic) don't have the circle around the "D". If it's just a 3 speed automatic, it's a Turbo Hydramatic 400, commonly called a Turbo 400 or simply 400.
Bad fuel pump will cause the engine to stall or not start at all. A bad automatic transmission will cause the vehicle to jerk and not run smoothly.
There are many signs of a bad transmission and it is important to know them. Some ways to tell if transmission is not working right, would be rough shifting, leaks, and warning lights on the dashboard blinking.Ê
It's in a Failsafe mode! (electrical problem) Take it to a tranny shop tell em if they can hook it up to a computer for the tranny and hopefully they'll tell you the problem....

If you do not have working tail lights on your GMC vehicle it may be an issue with the wiring or your lights may be burned out.
