Today I took my car to the shop, to see if it was low on transmission fluid I’ve experienced my transmission slip like 4 times over 2 years when the mecanic loosen the transmission bolt the transmission fluid came out dark red brownish and it smell like burnt transmission , he said the transmission was bad ofcourse he would say that , something tells me all I need is a transmission fluid change the car has 170k miles and it probably has never been changed the level was fine what do you all think????

 

I think you answered your own question. That would be my first step and most cost efficient, then go from there.

 

Keep in mind that when transmission fluid and filter are changed on a C5 Auto, only about half the fluid is is actually drained. the rest is in the torque converter and other works. If the shop is accurate on the fluid condition, two changes are in order.

If fluid changes are not done in accordance with the Factory Service Manual, fluid level can be too low.

If the shop you utilized did not check fluid level in accordance with the Factory Service Manual* with the engine running-- Trans in park after cycling through gears, the fluid level is low.

*Changing the fluid and filter on a C5 A4 is fairly easy, but there are specific procedures to insure that the fluid level is correct after the change:

After replacing the filter and bolting the pan back up, fill with new fluid to the drain/ check level plug hole. Then start the engine and leave it running with the transmission in PARK.

Immediately add fluid through the drain/ check level plug hole until fluid flows out of the plug hole. It may take as much as another couple of quarts.

With your foot holding the brakes, cycle the transmission through all the gears, then back to PARK.

Go back underneath and make sure that fluid is still dribbling out of the fill/ check level plug hole. You might have to add some.

With the engine still running and the transmission in PARK, monitor transmission temperature on the DIC. When transmission temperature rises to 122 F, put the plug in the fill/ Check level hole. Keep a pan under the hole, fluid will dribble out as the transmission temperature rises.

Do NOT shut the engine down until the plug is in the fill/ check level hole. If you do, HOT fluid will gush out and the transmission will be low on fluid.

I recommend full synthetic fluid.

Keep in mind that the above procedure drains about half the fluid in the A4. The other half is in the torque converter and other works.

You will need a small hand pump to pump the fluid into the fill/ check level hole.

 

Thank you so much!!! I think I may need to take it to the dealership 😅
