I just got a used early 2010 Honda Jazz 1.4 EX semi automatic (GG6). I want to change the gearbox fluid myself, I have got the Honda CVT fluid, as it is nearly 5 years old. I see the drain plug. but cannot find a dipstick tube or filler plug. Or is the filler plug the square drive plug? also what are the quantities for change and total ( if required). I see there is still no Haynes Workshop manual for late 2008 onwards. I have changed everything else (air, oil and cabin filter. Brake fluid, coolant, engine oil and brake pads). I would be happy to do gearbox myself to inspect the fluid. I have I-Shift version with the +/- A/M shifter. Thanks in advance!
