Well the 603a turbo motor running perfect when all of sudden yesterday the transmission failed to engage. The engine would rev but no forward movement. I checked my fluid and discovered it was too high. I drained it to the proper level but still nothing. The fluid was the nice red color not brown and did not smell burned.
I checked my vacuum and linkage connections. All were as they should be.

I can put it in gear and without touching the gas pedal it will move forward and in reverse on its own. If I apply the gas the engine spins and it does not engage.

Luckily I was able to get it into my garage before it refused to go any further.

Any help is appreciated.
Mark
