C6 trans refill quantity
I have an '87 F150 with a 302 and C6 transmission. I think the dipstick reading may be faulty. When I drop the pan to do a filter and fluid change, It takes almost 10 litres/quarts to get it to the fill mark (when hot idling in park). The Ford shop manual says to add 6 quarts and top up as required. There is quite a difference there and I find I am developing leaks that may be attributable to overfilling. Has anybody dropped the pan on their C6 lately and refilled it and if so, how much did it take to top up the system?
Thanks and have a great day.
