I recently purchased a '98 TJ, 4.0, Auto with 142,000 miles, sight unseen, with no history or knowledge of whether the thing ran or not for $500 from an auction. Had it towed to the house and started cleaning her up. Put a jump box on and she fired up. Fluids are clean, still within mileage of last oil chage (evident of windshield sticker). A/C even blows ice cold! So the interior was nasty. Pulled seats, carpet and console and cleaned everything up. Now for the problem...replaced seats and was going to move her. Started up great put her in drive...nothing...reverse...nothing. When I shift the transfer case I get slight grinding, but does cycle through 2HI, 4HI, 4LO. Any ideas on what the problem may be?
