mixed tranny fluid. problem?

2002 F250 5.4 Crew with limited-slip diff.

I put in about a quart of MERCON-compatible this weekend when the level was low. Found out that last tranny flush used MERCON V.

Now I have at least a quart of the MERCON-compatible in with the MERCON V fluid.

Should I not worry and just use MERCON V from now on, or will the two fluids have problems in my tranny?

Thanks for any help!

You'll be fine, 1qt out of 19 won't hurt anything.

It's like dividing by zero. We're all doomed.

Dividing by zero would give the infinity, is that what you meant ?

or dividing by one (gives the same ).
