The transmission fluid in the 1998 Audi A6 is designed to protect all of the seals and gears inside the transmission. When the engine is not running, the transmission fluid is housed inside the transmission pan. Once the engine is running and in gear, the transmission fluid is circulated throughout the transmission. The fluid is able to protect all of the seals and gears by cooling and lubricating these parts. The fluid will need to be changed between 60,000 and 75,000 miles.
Things You'll Need
- Jack stands
- Fluid catch pan
- 1/2-inch drive ratchet
- 1/2-inch drive socket set
- Clean rag
Park the 1998 Audi A6 in a safe and level work environment. Set the emergency brake.
Jack up the front of the 1998 Audi A6 and put the jack stands under the designated front jacking points on both sides of the car. Then, lower the Audi onto the jack stands. Pull the jack out.
Move the jack to the rear of the Audi and jack it up in the air. Place the jack stands under the designated rear jacking points on both sides of the Audi. Then lower the car onto the jack stands. The whole car has to be on jack stands so that you will be able to get an accurate transmission fluid reading.
Crawl under the driver side of the Audi near the driver side door. Locate the transmission pan on the bottom of the transmission. Then, locate the transmission fluid fill plug on the very front of the transmission pan.
Slide the fluid catch pan under the transmission fluid fill plug on the front of the transmission pan. Then, remove the fill plug with the 1/2 inch drive ratchet and socket by turning the fill plug counter clockwise. Pull the fill plug out of the pan.
Crank the engine and let it run for about two minutes to heat up the transmission fluid. Keep the engine running while checking the transmission fluid level.
Stick you finger inside the fill hole and locate the fluid level. The transmission fluid should be either coming out of the fill hole when you remove the fill plug or the fluid level should be at or near the plug hole with the engine running.
Put the fill plug back into the pan and tighten down with the ratchet and socket. Remove the fluid catch pan from under the car. Turn the engine off and reverse the steps for jacking up the Audi to remove the jack stands.
Tips & Warnings
- If the transmission fluid is low, add fluid to the fill hole until it starts to come out of the hole.
- Use extreme caution when crawling under and working under a car that is on jack stands.
