My truck jerks from 1 to 2!
Has the code on this as after installing ever pop back up?
Very informative with awesome time-saving tricks. Thank You!
What scan tool are you using ? And thanks for the very informative video almost any trans shop would use this code to say that the tranny needs overhauling. Is the lock up shift causing a noticeable thump with the fitzall hack ?
Will this prolong the tranny life?
Your back!!!
