So I've been having some tranny issues (clunky, shudder between 1st and 2nd, very UN-smooth) with my 2010 Taurus. I had it flushed about 5k miles ago and last weeks diagnostic at the Ford dealership was inconclusive. So I did some more digging and I found the original receipt from the flush and it says they used "Gulf All-Vehicle ATF" fluid (http://nu-tierbrands.com/products/transmission-torque-fluids.html). First off, according to their website an "All-Vehicle" fluid doesn't exist, they have Universal and Multi-Purpose (same thing pretty much, but I find the difference in nomenclature interesting regardless). And most importantly, the ONLY fluid produced by Gulf that can be used in Mecron LV applications is "Gulfpride® Synthetic Multi-Vehicle DEXRON® VI ATF", which certainly is not "Gulf All-Vehicle". So I'm fairly confident the fluid they used isn't Mecron LV suitable. But I mean this is a professional shop, how can they not check those kinds of things? I find it hard to believe they didn't use the right fluid. And I can't comment on how the tranny acted before the flush vs. after because I had the flush done 1 day after purchasing the car.
Could this be the culprit? Would using a fluid suited to Mecron V cause issues in a tranny requiring Mecron LV? I mean clearly it would. I don't know! I just want your guys' opinions!
