Wife and I headed out yesterday morning for a day trip to the Georgia swampland. Taking off from a stop light in Jacksonville we heard a gear grinding sound coming from down under somewhere. Na, that’s not my truck as we both noticed a beater looking car moving out on my right side. At the next light I felt it! When the automatic shifted from 1st to 2nd it made a sound that is described in my service manual as “growling, grating, or scraping noises”. The Temp gage was at 140 deg. (normal) and it only did this noise going into second gear. Coming down in gears is ok, and I can back up fine. I have never had to do major work on the transmission. I plan on looking at the fluid tomorrow for debris in oil. I have never had the bands adjusted and the truck is now at 116k miles. Can you all come back with some info or point me to some threads of others who have had this going on with their transmission. Thank you TDR members.
