Trans Shutters

[COGGER]

I have a 2008 F-350 long box. I was pulling my 27ft camp trailer this weekend and noticed from take off to second gear the trans shutters pretty good. Does anyones else do this?

Well, no, but it might help to know a little more about your truck and trailer (approximate weight). Is your truck factory stock, or does it have any modifications? Mileage? Past use or abuse?

Mine shudders a bit some times too, but it is usually when at wide open throttle shifting to 4th gear while putting out somewhere around 540 HP and 1050 ft-lb of torque. So I can't blame the transmission for that.. If some one twisted me that hard, I might shake a little too.

BTW,

THE TRUCK IS STOCK WITH 32,000 MILES NO ABUSE. TRAILER WEIGHT IS 7300LBS. IT EVEN DID IT ONCE WITH A YARD OF ROCK IN THE BED.

My 08 does this with a boat on the back. Does it when I axcel a little hard. Not so much out of the hole but more in second or third gear. The kind of axcel you do when your in traffic for example and you need to get going a little quick. I figure on asking Ford about it when it needs to go in sometime. Doesn't seem right. My boat loaded heavy is under 5 K.

No mine does it under normal acceleration with the trailer.

Probably axle wrap. If the springs aren't loaded enough when pulling a load it will be worse.

Is there a way to correct this?

Mine does it to its hard to explain ive taken it to the dealer they updated the software or something it doesnt do it as often now

There's a TSB regarding shimming of the rear axle to set the pinion angle. You may need to compromise. You may rid yourself of the shuddering while towing, but it may create a shudder while unloaded.

The truck is not overloaded? Not too much weight on the truck?

My '08 shudders from a dead stop when pulling a heavy load- has done it since new. It would bother me, but my 2000 did the exact same thing the whole 8 years I owned it. I'm sure it's a spring wrap-up thing, putting the rear u-joint at a bad angle.
