On the way home from vacation 250 miles pulling a 14k 5er I had some problems. First 70 miles from home my ABS light came on I checked everything out the best I could and found nothing. Still had brakes so on I go. 10 miles from home the truck shifts weird on a on ramp and the OD light blinks and I lose my speedo. Once up to 30 MPH the speedo starts working again. The last ten miles I drive it very easy and make it home. After parking the trailer I go for a short drive !/4 mile while the OD light didn't blink after restart the ABS light is still on and the speedo doesn't work until I get over 25 or 30. I have a 2000 7.3 auto. Thanks.
