Just bought it.. been siting for 9 months. Changed trans. pan gasket & filter among a ton of other things. I think it's the seal in the gear shift assembly that's leaking Bad! I pulled the trans. pan back off and can't tell how get the assembly apart? From 3" above the pan I can get shift lever & throttle lever off but how does it come out? Out the top? Or Bottom inside the pan? There a couple of allen screws in the trans. just under the shift assembly inside the pan area that are in the way. Thanks
