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

Is your tune written to accommodate the CAI and those tires?

How many miles? And was it flushed? is it a custom tune?

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?

How are you guys reading your trans fluid temps? Is it with the tuner?

With my Edge I read my trans temp and I'm running around 150 or so, think you're running pretty hot. I've had the shudder issue as well. I recently got a blue tooth OBDII adapter and the Torque app, total about $10-12. It lets you see live data that your tuner doesn't and see your misfires, along with a ton of other info. This morning I had misfires from cylinder 7 and 8, so I'm going to swap the COPs out with other cylinders and see if the misfires follow the COPs, if not I'll have to put new plugs in.

This is the adapter I bought.
