MT643 Fluid Capacity

[MEFBUS]

1994 Blue Bird All American headed for Haiti. Want to do a fluid and external filter change. Any insight as to how much fluid I should plan for? Went to Allison's web site but didn't have any luck. Thanks.

I am guessing 12-16 quarts.

Johnny should be just about right for a drain / refill.



a completely Dry 643 will hold just about 5 gallons.. thats including the cooler loops and dry external filters.. (and with the deep pan).. if the dipstick goes into the side of the pan you have the deep pan..

The drain and fill/filter change should be similar to my AT545....
