Not competent?
I do transmission fluid exchange services all the time. And when done correctly can allow a transmission to go many miles without a problem.
Ask the owner of a 1998 Toyota Camry with 190,000 miles on it. Original automatic transmission. Fluid exchanges done every 30,000 miles.
Ask the owner of a 1999 Honda Accord with 230,000 miles on it. Original automatic transmission.
Ask the owner of a 2000 Ford Taurus with 250,000 miles on it. Original automatic transmission.
Now ask the owner of a 2000 Chrysler Cirrus with 78,000 miles on it. Only did one pan drop fluid exchange at 35,000 miles. Needs new transmission.
Ask the owner of a 2004 Chevy Silverado with 120,000 miles on it. Two pan drop fluid exchanges at 50,000 miles each. Needs a new transmission.
If doing transmission fluid exchanges makes me incompentent to even put air in a tire, then that must mean I don’t know what end of a scredriver is the business end when I recommend an oil and filter change?
