the transmission in my 6.9 has become all neutral. no engagement in any gear. this happened just after i started the car in the morning. i backed up about 3 feet, and that was it. prior to this, it worked perfectly, with no noises or malfunction of any kind. when i checked the fluid level it was very high. can anybody tell me anything? it was suggested that i check the auxiliary trans pump located below the ac compressor? help!
