hey mr. allison,
i have a 2002 chevy duramax 6.6 with the LCT 1000 allison. recently i lost reverse. when it is in the reverse position the R just flashes and its not shifting into OD. i was told that it could be the nuetral safety switch. so i replaced the switch but its still doing it. so i called the chevy dealer and they said that the allison doesn't have to have the program reset. so that means it is something else. if you could assist me it would be much appreciated. thanks.
