So today my truck started to shudder when its in drive and start to takeoff. Truck has been running/shifting fine before today. It does fine shifting through all the gears, and doesn't shudder once i'm above like 7mph. It does seem like shifts are slightly slower, but that could be my imagination. Also, if i put the gear selector to 1st, it seems like it shudders just a little, but not as much as when in drive. The torque converter is still factory, after 2 tranny rebuilds and 205k miles, so could the TC be bad? I've read that it could be a driveline issue as well? The carrier might need to be shimmed or something? I havn't lifted my truck recently, so the driveline angles are the same. i did notice that the carrier (thats the piece that connects the 2 piece driveshaft correct?) was a little loose, but isn't a little of play normal? Any help would be great. Thanks, Mitch.
