Where to check transmission fluid on a 2001 jaguar xjr

If there is a red dipstick, check it from here.
If no dipstick, then you will have to go from underneath and look at tranny. There will be two plugs on tranny. A lower drain plug and upper fill plug. You can remove the upper fill plug, put finger in the whole and you should be able to feel the fluid. If not, add some, You can use a rubber hose and funnel or top with hose on bottle to help fill it up
