Transmission drain and fill

[pmezo33]

Anyone know where to find the drain plug on the 6f55 and about how much will drain?  Figure it's one more thing to get done on my checklist.

I tried using the mityvac through the dipstick and was only able to get just under 2 qt's out.  The level was fine before and i filled up what i took out, but definitely not the most effective or efficient method.

Should get 5 quarts per drain.  3 drain & fills should simulate a flush.  Don't have a pic of the drain plug on the 6f55, but on the 6f50, it looks like this:

Great pics... thanks.  Am i pulling both of those plugs to drain?

No, just plug # 1.

I was getting just over 4 quarts per drain for what it's worth...

We got somewhere between 5 and 6 in.

My plan is to do that, ptu, and rdu yearly at the same time.

The 15 trans runs much cooler, the amsoil and the coolers work excellent together.

Just did the PTU and RDU about a week ago.  Now it's time for the transmission.  I'm planning on doing this yearly too and all about the same time.
