First of all make sure you are checking the fluid right. Some people do not know that in order to check transmission fluid the engine needs to be running and the temperature needs to be sort of warm althought you should be able to get a good Idea just by the engine running. In this instance you might have a governer valve that isn't properly working to shift the engine when hydraulic pressure reaches a certain PSI. I would suggest having it flushed and put in new fluid and filter. If this doesn't work the problem is more serious and might need some professional assistance.

start checking the trans fluid level, a trans filter change and trans flush should help.

SOURCE: my transmission slips in drive but not overdrive why?

well overdrive is really where your suppose to have it when you hit the highway. Seem now the gears are slipping in (D) mode. if you want to save more time go to any major parts store and purchase TRANSX. pour it in and drive off.

well the low cost way to go first would be to try and change the trans fluids. If the problems still remains the it may be an internal problem

sorry to say this trans has to be removed and rebuilt seems like od clutches burnt out-do you tow heavy trailer with truck as you have to tow with od off(push button on shifter)
