Jaguar XK8 Transmission Fluid/Pan Change

How to change the transmission fluid and the pan on a Jaguar XK8 with a ZF 6HP26 transmission (2003+).

By the way... this same transmission is used in many other cars. Ford uses it in their Lincoln Navigators, BMW uses it in some cars, and Huyndai uses it in the newer Genesis.

wow great video im a guy that never takes his car to a shop a total diy'er this is my first jag (01 s-type) and the tranny started slipping figured id change the fluid first before i bought a whole new one... one question though how was the out come? doing it your self have you noticed any thing different ie. smother shifts things of that nature? basically would you recommend me to do it? i went to school to become a mechanic learned nothing on jags though. also in the end how much did it cost

@brondondolon1 The transmission has been smooth as silk since I changed the fluid. I was getting some hard shifts before the fluid change, especially when the transmission would downshift at very slow speeds (like when slowing down to stop at a stop sign. Overall, if probably cost me about $200-$250.

@sam1174 Neat well done video Sam. My Jag dealer tells me that I need this same preocedure on our 2004 XJ8 as small cracks have developed near the bolts and tranny fluid is supposedly leaking. They have quoted $920 to do it. It's interesting that no oil is in the driveway?

@topremf No drips on the driveway??? That sounds odd. I guess it's possible because the transmission warms up as you drive away, and then it cools down when you park. As the transmission warms up the fluid expands. Then when you park the transmission cools down and the fluid contracts. That negative pressure could keep the fluid from leaking in your driveway, but it might be leaking on the road.

@topremf Just start the car and let it idle for a half hour or so in the driveway. Then check the driveway. If there are still no drips, I'm guessing that the transmission isn't leaking.

I have done the same on my BMW, and I'm totaly impressed you did it by yourself AND record it on film also! Superhuman! :D

The oil Jaguar uses is a mineral oil and should not be substituted. We flush these 6hp26's out when they come in with problems from the wrong oil being used.

Hi Sam, Thanks for filming another great vid! It's very kind of you to take the time to record, explain and instruct. Just wanted to say thank you! it's a great help!!!

@vincentesquilin The transmission is actually manufactured by a German company called ZF Friedrichshafen, not Mercedes. Ford uses the 6HP26 transmission in a few of its cars, and those transmissions are filled with the Mercon SP. Mercon SP exceeds the Shell specification for the ZF transmission, that's why Ford uses it.
