I had a full load of cattle on I-64 on North Mountain. Had in cruise but was not holding back. Heard a noise I thought was tire noise. Stopped was in gear but would not move. Put in low range engaged, moved 200yds put back in high range. Had to do 2x before engaged. continued to stock market. Brought back 6,000 load , going downhill same thing. after stopping and starting 20 times I noticed when I kept foot on brake would stay in gear. After made it off mtn worked fine until going downhill, kept foot on brake and stayed engaged. made it home. Haven't started anything hope you can tell me where to start. Thanks
