Nuthin better than a bath of Kendall motor oil 20-50 followed by a spray of Kendall transmission oil.
Every time I think, I have done this enough times to avoid the giant mess. Every-time I underestimate how messy I am. Maybe next time. The engine oil was 13 month old and had 6,000 miles of driving. Normally I do an oil change every 12 months. I knew the road trip to Florida was not a big deal, so I waited until I got home. My transmission had the differential fixed a year ago, and I want to get any pieces of metal that are always left behind after a rebuild, so I have done a second oil change after the rebuild. The magnets all look good and just normal tiny amount of stuff.
I will not do an oil change again until I return from Palm Springs, CA next year. I will likely not do a transmission oil change for 15,000 miles.
A shower od soap and water sure is nice after a soaking of the wonderful smell of transmission oil.
