How to Change the Transmission Filter on a 2005 Z-71

A 2005 Z71 is a full size General Motors pick-up truck with an eight-cylinder engine. The transmission filter needs to be changed every time that the transmission fluid is changed. The transmission filter is located on the side of the transmission secured to the bottom of the transmission fluid pump. You will need to have basic mechanics tools and a clean work area. Changing the transmission filter will take about 45 minutes.

Things You'll Need

• Jack
• Jack stand
• Drain pan
• Ratchet set
• Replacement transmission fluid

Instructions

1. Raise the front right (driver) side of the frame using the jack. Lower it onto a jack stand to get under the transmission.

2. Place the drain pan under the transmission's drain plug. Remove the plug using the ratchet set and drain the fluid into the pan. Replace and tighten the plug

3. Unscrew the filter from the transmission fluid pump to the right of the transmission. Fill the new filter with transmission fluid and screw it into the fluid pump.
