Gearbox oil changes

[Chocolatemonk]

Does anyone have a view on auto box Oil changes/ intervals?

On which Jaguar? By auto box I am assuming you mean the automatic transmission rather than the transfer case that is found in the x-types? Following the Jaguar spec is the best idea if the vehicle is driven normally, if it is driven hard then I would shorten the interval. Automatic trans fluid will degrade with time and mileage which will lead to internal components wearing quicker than if the fluid were maintained at proper intervals. Let me know what vehicle we are talking about and I can get you more information on intervals and procedure.

Thanks for that info, I have XKR with 5 speed Mercedes automatic transmission, the car has done 82k miles, I'm not sure how its been driven but I intend to drive it hard! My gut feeling is to get it changed even though Jaguar say 'sealed for life'. I have a friend who builts automatic gearbox's and he can do it for £100 that includes the filter and Oil!

If you plan on putting some good hard miles on it then I would say changing up the trans fluid with some fresh stuff is a wise investment. I did a little bit of of looking around, the scheduled maintenance for a 2001 XKR doesn't stipulate an interval for the trans fluid(sealed for life). For the Mercedes 5 speed w/4.0 liter SC it shows the fluid as being a Shell ATF 3403 M115 and part number JLM 20292 with a quantity of 9.5 litres (10.0 US quarts). If you can get it changed for £100 with proper parts then that is a pretty good deal, labour rate for drain and fill with filter change is 1.3 plus parts.

Thanks very much for that very accurate information, I think I will get it done for peace of mind!

You are welcome, easy stuff to look up on TOPix.

Hi Martin, Jaguar state, I believe automatic gearboxes are sealed for life. What is life? Until it fails I guess. I believe that if an automatic box has done 60K it is worthwhile having the Oil changed along with the filter etc. it is not that expensive and will be of benefit. If you know of a good independant garage who will do the job for you go to them it will be cheaper than Jaguar. Best wishes mate Geoff.
