I just turned 100k on my 08 Hemi Ram--Love the truck--it has started a very slight shudder sometimes when put in reverse--it is not very noticable and does not do it all the time--seems to run just great but I can feel it and wondered what was going on. Would fluid and filter replacement help and if so do I need to adjust any bands? I have done dozens of band adjustments on 727's but what do I need to do while pan is off for fluid change? THANKS!!!!!
