BLINKING OVERDRIVE LIGHT IN SHIFTER, RUMBL

1996 Ford Bronco

Transmission problem
1996 Ford Bronco V8 Four Wheel Drive Automatic 214000 miles

While driving at speeds where the Overdrive kicks in and vehicle is moving up an incline, the truck starts to rumble and shake. Take the foot off the gas and the rumbling stops. When pressing harder on the gas to down shift, this also stops the rumbling and shaking.
Now the “Overdrive” Off Light is blinking, the transmission is shifting hard when taking off at a slow to normal rate of acceleration. Transmission fluid is full and appears to be OK. Transmission was serviced at 175000 due to leak at front seal.
Suggestions?
