I cant believe this
So I just bought my first diesel pickup. An 89 F250. I bought it about two weeks ago. I had to replace the mechanical fuel pump, but other than that it was good to go. So I was driving on the I-8 today doing about 70MPH, and all of a sudden, the RPM start to climb, and I am loosing speed. So I push on the gas a little more. The RPM climb, but no power getting to the wheels. So I put in #2 gear. Same thing happens. Put it into first. Same response. Reverse. Same. Its like the damn thing was in neutral. Any ideas on what could have happened. We just filled the transmission with fluid a few days before (it was about 2 quarts low and it was shifting better). I thought that the torque converter may have gone out, but there was absolutely no sound when it went. Thanks guys.
