Two problems related to automatic transmission park/neutral start switch have been reported for the 1999 Ford F-350. The most recently reported issues are listed below.
Transmission system malfunctioned, which while reversing and pulling a trailer, transmission overheated and burned out. Dealer redesigned the transmssion and cooling system. Vehicle was still experiencing the problem, and vehicle downshifted, it did not slow down the vehicle. Please provide further information. The vehicle is not equiped with mechanism to control vehicle's speed when descending steep grades. The transmission failed twice prematurely. The transmission also over heats under heavy load and when driving in reverse.
When on a downhill of about 20-25 degrees when vehicle is placed in park after a couple of seconds it will roll 2-3 feet then stop this is duplicabale although after 2 times it will not do it again until on level surface and then back on hill. I almost rolled thru my gate at my house.
