Transmission seems to work fine until it gets hot, then it will still shift but very harshly. Eventually it will get to the point of not shifting out of first at all, If I accelerate to about 25 mph in first and then shift to neutral and then into drive it will upshift for a moment and then downshift back to first again. Sometimes if I repeat this procedure enough times it will straighten out and work fine again. Transmission has been serviced within the last 20000 miles. Any ideas? All the mechanics are baffled.
Thanks Dave
