So after getting the truck a tune-up and safety check, I took it down to our local State Beach parking lot (now that all the thousands of tourists are gone) to get a little practice with shifting, and after 3 practice runs, gave it a try on the road. There's a bit of grinding, but mostly because there's no tach, and I have to force myself to pretend it's loaded, and shift at a much lower speed that I really need/want to.... But on the whole, I thought this wasn't too bad for my fourth try of shifting through a few splits..... The file was too big to post here, so here's the YouTube link: I have the recommended shifting pattern for a B61 from a manual, but it's for a triplex. Does anyone have an actual manual page that shows the recommended shifting pattern/order for a quadruplex for both upshifting and down shifting? I know that for the triplex, they point out which shifts can be skipped, because the ratios are so close, and I'd like to know which ones those are.... Mike
