I bought a "new" 100 Series 3 months ago, it's a 98 with 49K miles, I have put 4k miles and everything works fine. I intend to use it as a daily driver with some moderate off roading and hopefully keep it for a long time. I'm impressed by this forum and the level of involvement of it's members, some seem to know a thing or two about TLC's. Couple of questions: 1) The tranny shimm from 3rd to OD that is mentioned in some of your postings, how serious is as a problem? Is something worth trying to fix before it actually mess the tranny? Is there some type of prevention and or symptoms to look for? 2) I have the Michelins Cross Terrain (almost new) which work very good on pavement ( dry,wet,light snow/ice) any experience in how they withstand some off road use, mostly dry rocky terrain. 3) Any advise on preventative maintenence to assure looooooong life ?
