07king-ranch

Question I hope someone can answer. I have a 07 F150 Kingranch 5.4L with edge evo, volant CAI, all plugs,coils and trans fluid were changed. At about 35-45mph I get what I think is a torque converter shudder. Trans temp is running around town at between 200-215 degrees and that's when it happens most. Any ideas I was running 35/12.50/20 tires and thought that might be it. Currently went back to stock 275/55/20 and shudder is still there and temp is still high. Torque converter going bad? Or fuel injector? Oh ya no check engine light either Any help would be appreciated Thanks

My 2004 XLT 4X4 with trailer to package and cooler normally runs 150 +/- 5 degrees when not towing - city or highway are the same.
Yours reaching 215 is pushing the upper limits.
What type of fluid was put in?
Was the filter replaced?
Was the change a flush or a pan drop and change?
