The most common cause of this is low trans fluid. Check it warmed up, on level ground, idling in park.

Re: 99 4r100 problems

Trans fluid is full And still looks/smells like it should checked that first thing could it be the torque converter solinoid? I've been surching around for info and haven't found much it never felt like it slipped or anything the OD light flashes does this mean it threw a code? I'm 20 years old and I don't know to much about inside a trans

Yes, if the overdrive light is flashing it has set a code. That would be a good place to start.
