you have a bad torque converter clutch solenoid in the transmission. on the older transmissions you coulod just unplug the white plug on the transmission and that qould take care of the problem but im not sure on the 95. you might as well try. looking down at the transmission from under the hood look towards the front of vehicle(transmission) and you will see a white plug about 1inch square. unplg it and drive the vehicle, if it still shifts fine then your all set, if not then you need to replace the solinoid
