SLAMMING INTO GEARS

1994 Ford Bronco

Transmission problem
1994 Ford Bronco V8 Four Wheel Drive Automatic 183000 miles

Sporadically the transmission is not wanting to shift gears so RPM runs high then slams into gear. Turn car off then restart and it usually goes away. Also does not happen all the time.
