| Tranny flush or change
I recently purchased a 2006 lly w/ 95,000 mi. tranny has never been flushed and fluid is in good shape, red no burnt smell.wondering if I should have it flushed or just drain it and replace the filter and if so what fluid should I use that is compatible with current fluid. |

| Just change it! I had my (last) truck flushed and had problems ever since and now I have a new truck. My brothers good friend works at Ford and said that it might make an existing problem worst and then again it might be just fine | |

| Always remember that there is a possibility of you getting someone's trash when hooking your tranny up to a flush machine,better off doing it by hand..

If you want to do a complete exchange you can disconnect the trans. cooler return line and drain into a bucket. Just run the engine for 2-4 seconds, turn off and replace with new fluid. repeat until clean fluid comes out of the hose into the bucket. It will take about 5 gallons to do this.

| I do not even change the fluid. I had a truck with 180,000 on the clock. I never changed the fluid. They guy that bough the truck changed the fluid the next day and the transh took a shit. All the clutch material in the fluid is good for it it keeps everything working you take the material out and it starts to slip.
I NEVER EVER CHANGE THE TRANS FLUID IN ANY VEHICLE I OWN AND I HAVE NEVER HAD A TRANS PROBLEM!!!!!!!
