I managed to shift into reverse will moving forward at 30 mph. The rear locked for 1/2 sec and I was able to get back into neutrel and restart the engine which had stalled. The truck seems to have suffered no ill effects and no codes where set in the computer with 186000 miles and all original equipment I'm sure this wasn't part of the recipe to add longevity. Any other boneheads have experence with this? As I just recentley serviced the transmission do you think I gain anything by dropping the pan again and or what would be the 1st symptom of impending Doom. Thanks guy's Tim
