A question on fluid- I have a 2005 Lariat 4x4 (5.4L 3V). The trans stick says use Mercon V. Years ago I did a fluid change on my 2001.5 Passat. That "sealed" transmission was very picky about fluid. I had a choice between Pentosin (expensive) and Pennzoil Multi-Vehicle ATF. This is a Synthetic Blend fluid. Cheaper than the Pentosin, it was still very expensive and I could not find it locally. I still have 4 quarts sitting on my shelf and no longer own the old Passat.
The bottle says it meets a number of GM, Chrysler, and Allison transmission specification, as well as Ford Mercon and Mercon V. I'm assuming this will be ok in my 4R75E?
