All 5-speed transmissions tack

Manual transmission filler location

  1. Park the truck on a level surface, turn off the engine, apply the parking brake and block the wheels.

  2. Remove the filler plug from the side of the transmission case with a proper size wrench. The fluid level should be even with the bottom of the filler hole.

  3. If additional fluid is necessary, add it through the filler hole using a siphon pump or squeeze bottle.

  4. Replace the filler plug; do not over tighten.

hope this helps
