Hi guys, I own a 2007 F-150 2WD with the 5.4L triton V8. Currently at 167,000 miles and was wondering if I should have a mechanic do a transmission fluid change/flush on it? I’m the second owner starting at 97,000 miles and I’m not sure if it’s ever been done. Thanks!
please check the FAQ
never flush unless it's already worn out and you're trying it as a last resort.
