peter lena 8,814 #3 Posted August 22, 2021 @Dakota W. glad you checked that ! diesel fuel , atf , kerosene , use that as your flushing agent , there is an Allen plug in the bottom edge of your trans, look carefully , usually packed with mud or crud. use a small flat screwdriver to dig it out . also raise the front end to increase drainage. buy a new shift boot, cut it off with a razor blade , use dielectric grease on the shifter shaft for slide on easy fit. you might have to do this a couple of times , do you have a near buy cul-de-sac for road driving ? great place to flush around your cleaning fluid, use every gear and range , picture a flushing waterfall of oil cleaning out your trans. any new 80-90 gear oil will work . notice the color change in the flush , that's the moisture in there , once you get a good clean , keep an eye on it , I regularly check mine . put a can of carb cleaner in the gas tank and some STA BIL fuel treatment in there too , to start deep cleaning your fuel system on your driving time. glad to have you on board , anything else just ask , pete Share this post Link to post Share on other sites
