Automatic Transmission Fluid Change Recommendations

[Barry Johnson]

I never go by manufacturer's recommendations on any fluid intervals. That's what they want to get you in for breakdowns or failures. I change my oil, full synthetic every 3,500 miles. Direct injection with turbos creates alot of heat and breakdown. Front and rear differential, transfer case and transmission every 20,000. Might be overkill to some of you all but fluids are much cheaper.

Same 3,500 mile on oil. As now towing a 3500 lb trailer looking at doing the 20,000 mile for trans etc as well.

For those that tow with their Rangers, anyone adding additional cooling for trans an/or engine?

Went with aluminum pan which carries another 2 quarts. Has drain plug for much easier fluid change next time. Also changed the filter.
