Ok it just might be the transmission is on its last leg but I need help.

As of Sunday the Overdrive light is flashing periodically. Not every time but I would say about 50% of the time.

And now I noticed that its not catching gears as easy as it used to now the motor revs to about 3000 RPM's and barely catches from 1st to 2nd. If I let off the gas it will catch. Between all gears its seems to be doing the same thing.

Are the 2 problems related? Any help wpuld be appreciated. Will trans cleaner/treatment help Here are the vitals on the truck
