I have a 1991 FJ80 w/ 200k. It's been a great truck. It has recently lost all of it's power. It seams like the trans isn't shifting down (like it ius staying in 4th gear all the time). i know this is hell on my motor. Does anyone have a simular problem. It seamed to clear up for a while when I changed the tranny juice. Second problem The ring clip came off of the front passenger wheel, it sits under the dust cap and hold a shaft out. the shaft has a threaded hole in the center and teeth around. How do you get this dang thing back on. I can't figure how it ever came off. I saw that a few companies made a super charger for the 6 cylinder engine. does anyone have one, is it worth a flip or do I need to pursue changeing to the later 8 cylinder engine and can you do such a swap?
