texasjack Posted March 30, 2017 Share Posted March 30, 2017 I am going to purchase a 90 with 6 automatic. The owner said when it gets up to 55 it downshifts. I would like ideas on what is wrong with it. Thank you Texasjack Link to comment Share on other sites More sharing options...
omega_rugal Posted March 31, 2017 Share Posted March 31, 2017 ? from what i understand: you are buying a 1990 MJ with the 4.0 and auto tranny, when it reaches 55 mph downshifts from OD to D? Link to comment Share on other sites More sharing options...
texasjack Posted April 2, 2017 Author Share Posted April 2, 2017 That is true but I found a frayed downshift cable and that could be the problem. Thank you Link to comment Share on other sites More sharing options...
cruiser54 Posted April 2, 2017 Share Posted April 2, 2017 That is true but I found a frayed downshift cable and that could be the problem. Thank you That is NOT a downshift cable.........I'll bet you the guy/gal is experiencing torque converter lockup. Link to comment Share on other sites More sharing options...
