Greetings everyone! I am the proud new owner of a 92 with the getrag 5-speed. Of course the first thing i did was to change all the fluids since i had no history of previous mantainance(sic). . I had known about tdr from a friend before my purchase so i knew about overfilling the transmission. I used 5-40 rotella with one quart of marvel mystery oil in through the top pto bolt. After driving 2000 miles or so the transmission now makes consideratly less noise and doesn't grind going into 4'th anymore. I also use a qt of mm oil inthe crankcase of all my vehicles. I am not plugging mm oil but I got 465000 out of my last dodge gas truck and currently 320000 out of my el camino ss and still going strong. I alsouse mm oil in the fuel tank and have gained almost 2mpg in the new truck so far, probably due to mm oils ability to disolve carbon from the injectors. Any of you using this stuff too? I love my new truck. Oo. Oo.
