I picked up a whole bunch of Castrol Full Syn Multi-Vehicle ATF (not the import version) from Auto Zone back in December on clearance.
It is approved and licensed for Dec-VI and Ford LV use, not just "meets spec".
I jumped on it because I could use it I'm my 4L60e in my 2000 Silverado at its next service, or could usr it in current GM 1500's or SUV's and Ford F150's (if I ever buy one new or slightly used).
I would use your Peak with no worried. The Castrol was the first ATF i have noticed meeting both specs, though I wasn't really looking for a product that did that before.
