I have a 2000 4x4 supercab with a manual. After putting 3:73 gears in it it pulls my 5000lb. boat on a tandem axle trailer with no problem. Before I put the gears in it was a real dog with the trailer. I'm sure that's because of the dinky v8 that I have in it and not the transmission. I've been through 4 rear ends and no transmision trouble whatsoever. The tech at the dealership thought that my second rearend was a transmission problem, but it wasn't. I would worry about the rear diff before I would worry about the tranny. Did you know that the tranny is made by mitsubishi?
