The transmission dipstick on a 1998 Ford F-150 with an automatic transmission is
not readily accessible like on older vehicles. Most automatic transmissions in vehicles of that year and later don't have a dipstick. Instead, the transmission fluid level is checked by a mechanic using specialized equipment.
You will likely find a dipstick that looks similar to a transmission dipstick, but this actually belongs to the power steering system. Be careful not to confuse the two.
