Trans temp and od light is on what does this mean
Transmission Temperature light only comes on when the transmission has reached the operating limits and tells the temp sender to send a warning. The OD light is the Over Drive light.
There may be several reasons causing the Trans. Temp light to come on. The first would be if the transmission is low on transmission fluid.
Place you vehicle on a level surface. You can check this by letting the vehicle warm up to normal operating temperature, then open the hood and remove the transmission dipstick and wipe it clean with a paper towel or shop rag. Then reinsert it and remove it again, holding it horizontal look at the end of the dipstick. You will see a level mark and a add mark. If it's on the add mark then you need to add transmission fluid. Do not add more then 8 ounces at a time, before rechecking the level.
If the fluid is full, smell the fluid on the dipstick, does it have a burnt smell?
If the fluid has a burnt smell or it's a dark brown color then you will need to change the transmission fluid and filter.
The Overdrive light is on due to high transmission temp or because the Overdrive button has been pushed. ( If equipped with a manual overdrive button)
When the transmission is hot it will turn the overdrive off to increase the speed and pressure of the transmission fluid to help cool the transmission.
So this problem will go hand in hand if you find a problem with the transmission fluid.
You can also take you vehicle to you local auto parts store and have them check the engine codes. There may be another problem causing this issue.
