Tranny flush was not a power flush, just drained, put on new filter and added tranny fluid. The work was done at the local dealership where we have gotten all service done.
FWIW, we have had no symptoms of injector problems; no smoking, lugging, or loss of power. Sounds like they were just trying to make some extra money. If we had done all the flushes they were pushing, brake fluid, power steering, fuel system and engine coolant, it would have come to nearly $1,000. Personally, I have never heard of flushing brake fluid or power steering unless you have had some incident that caused a break in that system.
