okay so i was driving to get my new tattoos today for iraq and my truck kicked into drive aka 3rd gear and it locked up on me...i lost control then it acted normal..i drove about 300 yards and it did it again..now if its in drive even with od off it just revs i have 1st..2nd... reverse n park but no D n OD ...do you think its the whole tranny? or just valve body or torque convertor i have a month left before i leave for iraq and i dont even know where to start to look at for this problem..my buddy who is a ford junkie and a mercedes tech said check valve body and possible solenoids or sensors...another fellow svtp member lost his tranny about 4 months ago said he lost all gears but sounds similar..ne help will be appreciated thank you
