The weather will be getting better and I will be doing some preventative maintanence on my 88 fj62. I will be changing the trans fluid and clean the filter but have never done it before on any vehicle. I was wondering whether I should change the gasket to the pan, and if so which brand should I use? Should I change the gasket and filter before or after I drain and replace the fluid a few times( because most of the fluids stays in the transfer case)? Any other suggestions would be greatly appreciated. Thanks alot for the input!
