Safety Tip:
Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes.



1
Drive your vehicle to warm up the transmission fluid. Park the vehicle on a solid level surface. Set the parking brake and chock the rear wheels.
2
Using a floor jack, lift up the front of your vehicle. Secure the vehicle with jack stands on both sides for safety before starting any work. The pinch welds and the frame are the two best locations. Do not rely on the jack to hold the vehicle up while working.
3
Place a large drain pan under the transmission. Loosen the transmission pan bolts but do not remove. Starting at the rear, remove half of the transmission pan bolts. If the pan is stuck to the transmission, insert a flat head screw driver between the pan and the transmission and pry them apart.

4
Remove the rest of the transmission pan bolts and pour all of the fluid into the drain pan. If there are metal particles at the bottom of the pan and floating in the fluid, you may need a transmission overhaul.

Torque the mounting bolts evenly to the manufacturer's specifications.

Open the hood and locate your transmission fluid dipstick. Remove the dipstick.
