I've read all of your threads..what a GREAT site. Well my 2001 SuperCrew with just at 50K miles is going into the shop next Tuesday..thank GOODNESS I purchased the extended warranty that covers drive train.

I'm not sure what they will find as no code or check engine light has been set but this shuddering is HORRIBLE..low take off speeds...even at highway speeds in excess of 75mph (I check on purpose). I have no idea what is going on but I will be SURE to post here when I get it out and let you all know what is going on.

I'll be in touch and I STILL love my SuperCrew.

Peace
