Synthetic Trans Fluid

What synthetic trans fluid is everyone running?

i was thinking of trying Mobil 1

I like Mobil 1 synthetic ATF.

Does that include use in the 5R110 also Mark?

I am running the Valvoline full synthetic ATF. I like it trans temp went down about 10-20 degrees after I did the flush.

Does that include use in the 5R110 also Mark?
No! The 5R110 can only use MERCON SP. Mobil does not make a MERCON SP fluid.

I just wanted to make sure since the thread didn't specify which transmission. I only use Motorcraft Mercon SP, but Amsoil claims to meet the spec.
