My trans is sloppy. Won't hardly stay in gear. Have to hold the shifter up or down and fight it. Slinging oil out of seal on side. It will pull but u have to work at it. I know I will have to re seal it. But is there anything else I should do like bands or adjustments. Anything I should know first. Thanks. Oh yea. It's an old hustler. With k440 two stroke kohler. T20 trans I think.
