The transmission control indicator lamp (TCIL) is located in the instrument panel and is labeled O/D OFF. It is illuminated in conjunction with the TC switch.
The TCIL will flash if the EPC solenoid circuit is shorted or a fault has been detected in a monitored sensor used for transmission operation.

These details will help.

Thanks.

im not sure about the fan Try spraying the heck out of the entire assembly on the drivers side of the tranny with PB Blaster and as for hard shifts is it manual or auto? if auto change filter

Usually the drum inside the first gear is damaged/burned.smell the fluid. Look for a new transmission then

Honestly, while there is a chance that there is a bigger problem, it sounds more like its time for a transmission service. Hard thunking shifts when starting or stopping with no other apparent symptoms on older vehicles can usually be corrected by a transmission flush. if you pull out your tranny dipstick and the fluid is any darker than bright red and/or smells burnt (smell should make you cringe a bit) then take it to a shop and get it flushed out. I recommend a service center that uses a BG power flush unit. These services seem expensive on the surface but only have to be done about once every 3 years and can prevent more costly and involved repairs down the road.

check the transmission fluid first .
============
overdrive allows the engine to run at lower RPM's , which increases the fuel
economy and also the transmission runs cooler

Have a mechanic check for loose wires going to the transmission. Usually when the OD light blicks it's because there is something wrong with the transmission. Have your transmission fluid checked. If it appears brown, dark, or smells burnt have it and the transmission filter replaced immediately. It may also be that you have a leak in the transmission and need to add transmission fluid so that it's at the right level.
