- 2002 XLT 4.6L
My 2002 XLT 4.6L 5R55W with 150K miles on has a shudder when accelerating normally through 45-50 mph. I had ATF changed at 98K (dealer) and 147K (DIY). It's had this shudder for years, lately its been getting somewhat worse. Doesn't happen under heavy acceleration, if I play with the gas pedal I can avoid it; but it always happens when accelerating "normally" through 45-50mph. I thought it was OD band, adjusted it per the procedure, noticed that it was quite loose, meaning that after torqueing it to 120in/lbs and backing out 2 turns, it was significantly more "in" than when I started (guessing at least 1 1/2 turns). Now here's the question: Is it normal for the "adjusting screw" to be really loose after backing out 2 turns? When I torque it down to 120in/lbs, its obviously tight, but when I go to back it out it feels really loose after only 1/2 to 3/4 turns. Does this mean that the OD band material is really worn off? I've considered trying it backed out only 1/2, 3/4, or 1 full turn, is that a good idea? I don't want to break anything. Adjusting it to 2 turns did help, but didn't completely eliminate the shudder.
I also had the PCM software updated recently, didn't help this problem. Would replacing the solenoid pack address this problem? Any response would be greatly appreciated.
