Hi from the New Mexico high desert up in the east mountains. Just traded an old Honda Civic for an old Tahoe so I can make it up and down the dirt gravel road and haul small loads of hay. 196k. Great shape. Getting bfgoodrich ko2 165/75r16 all terrains tires and bilstein 4600 shocks next week. Also an oil change, differential and transfer oil change. Hope I got it right... Not sure if I should change (but not flush) tranny oil? It's new to me but I really like my Tahoe. Any advice from those who know would surely be appreciated. Great forum. Thanks ahead.
