Automatic Trans. Fluid change problem
I have a 01 EB Expy and wanted to change AT fluid myself so I got out the manual from Ford and the Haynes manual to find capacities and fluid type which turned out to be 15.5 litres (16qts.) of Mercon. I dropped the pan, after draining the tranny, replaced the filter and gasket, replaced the pan, and put in 15 litres of ATF. There was loads of ATF running onto the floor so I drained (after several fluid reductions about 8 litres of ATF until finally I arrived at the hot-full line while the motor was running. It turned out that I had only initially drained about 7 litres of ATF. Why is the capacity of the 4R100 tranny given as 15.5l. when it holds only about 7 l.?
On another topic the Ford manual says not to change the rear differential gear oil ever, unless work has been done on the axle,differential, or the axle has been submerged in water. Okay, fine, but what about the front differential?
Thanks in advance for your answers. Artful Dodger

The capacites you found are for a complete teardown when the tranny is dry. A filter change usually only requires 3 or 4 quarts, depending on the tranny. 7 seems a little bit much, so after you get it hot running down the road, check it again. It may have too much in it still(I don't know this, I am not familiar with your particular tranny).
Most of the oil is in the torque convertor. On most vehicles, the torque convertor can't be drained, though Ford did make some were you could. On my 1980, I can take the flywheel covers off, bump the starter around, and take a drain plug out of the torque convertor. I can drain all the oil this way. I think mine(c6) takes about 14 quarts when I drain the convertor.

to much fluid
The reason you had to much fluid is you did not drain the torque converter which holds more than half of the fluid. What you did is called basically a tranny service. Change the filter and the fluid you get out of the pan and that is what you need to put back. Not sure if your torque converter has a drain plug on it. If it does you can drain it To get all the fluid is best done with a trans fluid exchange machine done by a repair shop.

The torque converter has most of the fluid, if you have the 4r100 then you should have a drain on the torque converter, look at the tranny and you should see a black rubber cap, that is where the drain plug is. I am actualy going to change my fluid and filter this week.

I find that dropping my transmission pan, replacing the filter, cleaning the magnet, and replacing the fluid is good maintenance on the transmission. I don't really care about replacing all the fluid at once.

Fluid Change problem
When I changed the Tranny fluid I also drain the converter. When I add the new fluid I only put in about 6 qts then I start the engine so that the fluid goes back into the converter then shut it off and add another 6 qts and repeat procedure. I usually end up adding around 14-15 qts total. I have a E40D Tranny in my 97 Expie 4X4 with 213K miles.
