Changing Fluids

November 2011 - I decided it was time to do some regular maintenance on my project car that was long overdue. I changed the oil/filter for the first time - I know, regardless of mileage 18 months is WAY too long between changes. I replaced the drain plug with a magnetic one while I was there. I also opted to replace the rear differential fluid with Valvoline synthetic. As for the transmission, I did a bunch of reaearch and the sources I trusted recommended Ford Motorcraft full synthetic manual transmission fluid. At $22 per quart it is rather expensive which is a shame because the pump I bought at the local auto parts store spilled about $30 worth of it all over my garage floor.
