Refill Transmission Fluid and Check Level

What happens here

Locate the transmission fluid filler neck, typically near the engine, which is also used for checking the fluid level. Insert a funnel into the filler neck. Begin pouring the new STP ATF+4 automatic transmission fluid into the transmission slowly. The presenter mentions adding six quarts initially. After adding the fluid, start the truck in a well-ventilated area and let it run for about five minutes to allow the fluid to circulate and warm up. Then, check the fluid level using the dipstick to ensure it's within the proper range. The presenter advises that the truck should be warmed up for five minutes *prior* to draining the pan, and then run again for five minutes *after* refilling before checking the fluid level.
