Alright, so as part of my "getting ready for lake season" maintenance, I wanted to change the transmission fluid. I noticed sealant around the cap which I assumed was a DIY gasket installed by the last owner/service shop. Once I removed the cap, I realized that sealant was holding the cap secured to the gearbox.
My question is what am I missing and why will it not tighten down? The bolt threads and tightens, but only tightens to the piece that sits on top of the filter. I did not remove all the sealant yet to to inspect the cap. I decided after trying to remove my fuel filter by tightening it for 30 minutes, it was time to call it quits for the day.
