No codes/messages on my truck, but the Xmsn shifts rough intermittently (worse in ‘eco’ mode) and surges (tach rev ~100-300 rpm) constantly at speed. Most noticeable between 35-55 mph (worse in ‘eco’ mode).. I know that if the xmsn is coming apart and not shifting correctly, it will throw codes that say something like ‘incorrect gear ratio 1:2’ or something. I can’t remember exactly.. but I don’t have any messages at all besides brake light out.. had stealership reset the xmsn control module. Did nothing. Could it just be a bad TC? Thx in advance. Can’t be the only one..
