Hey guys, I have an 89 F250 with a C6 behind the 460, I am going to change the tranny fluid and filter probably next week, I checked in the owners manual (suprising it was in the vehicle when I bought it) and it said something like 14 quarts, is this an accurate capacity if I am just dropping the pan and changing the filter? Seems like a lot, but I also know its a big tranny. Anyone who has done this if you would let me know I would appreciate it. Thanks guys

 

yes, 14qts is right if you drop the pan AND drain the torque converter.
Most of the old fluid is in the torque converter so it is good to drain it at the same time.

 

Thanks Lazy K, one question.....is there a plug on the torque converter than can be pulled in order to drain it? I dont believe I have ever drained a torque converter (without pulling it of course). I want to get as much of the old fluid out of the system, its old and starting to turn colors and I dont want it in the system at all if I can help it. Thanks

 

If you drop the plastic dust shield at the bottom of the bellhousing you can rotate the flexplate until you get the converter drain bung at the lowest position. Then unscrew the bung and have a couple of beers while it drains.
Don`t look for the bung on the circumference of the torque converter, it actually is through a hole in the flexplate and facing the engine oil pan.

 

Excellent, I will tackle this in the next week. Thanks
