Llooking to install transmission oil gauge in my 2014 Y61 Patrol 3lt auto.
I have looked at ones that attach to the top of the gearbox, ones that tap into the gearbox, ones that fit inline in the transmission cooler and scan gauges (which look far to complicated for me)
Would appreciate advice on which is the the most accurate type please. Also , one auto transmission place quoted me $800 to install!!
Thanks
