So I have a 96 Suzuki Every Van and I got it about 1 year ago. I've been doing preventaive maintenance in the last year and finally got around to changing the manual transmission oil. I can't describe how amazed I was at how poorly the oil condition was. It came out grey and brown. The plug had a 1/4" of sludge caked on it that was just a grey mush. Heres the picture of the plug before I cleaned it off: Pretty right? I cleaned it up and put about 1.5 quarts of Royale Purple 75-90W oli back in. Hopefully that will make the shifting that much smoother. Change your tranny oil people, its probably still the oil from the factory.
