Small "clunking" noise from under vehicle when shifting from park to reverse or drive. "clunking also evident when slowing to a stop. Ultimate transmission failure occurred while accellerating from a stop. A very loud "clunck" was heard from under the vehicle followed by a loud wirring noise. The vehicle would not shift from first gear afterwards until about 40 MPH. The "wirring" noise continued when the vehicle was stopped and the transmission would not shift into reverse.
While taking off from a toll booth there was a big bang and the transmission would not shift into reverse and made a very loud whinning noise whe going forward
