Heavy load and choppy takeoff?

[ScottyP5947]

Hey all I just hauled a full bed full of giant splittable pine tree rounds and when I was taking off from a light or slow on the freeway it sort of shuddered or shook a bit and when I accelerated it instantly went away once I rolled on the throttle a bit. It really was no biggie, it just was strange. Any ideas?

< I also got pulled over this weekend for passing a gas F-250 who was going 47 in a 50, I 'dusted him' and ended getting my ID run and a warning to 'slow it down'... I was going 85 when I passed the guy... good day! >

I get that too sometimes. Mine is a six speed, I thought that was why but your an auto, so maybe not.

Sounds like a TC going South!!

[ScottyP5947]

That's what I was afraid of. What do I look for next at this point? Pretty common failure on these?

When the TC is locked and you gas it, if the rpms climb faster than the speedo you have slippage. Towing heavy loads will really make it obvious. It will continue to get worse, keep an eye on your trans temp gauge when towing.

ok got it! things didnt get too hot and i will def keep an eye out for those symptoms from here on out. i really dont haul a lot very often, but when i do the a$$ is sagging so its all or nothing with my truck. i will say how great it rode with all those logs in there! tks for the replay

I'm thinkin axlewrap

Driveline angle. If the angle isn't just right, you will get a shudder. The shudder is more pronounced when loaded. There is a TSB for a shim kit, or you can get 1/4" thick pieces of flat stock, and cut it, drill the holes, and shim the carrier bearing. TSB number 16915.

And if you get a 'thunk' when you accelerate, your slip yoke needs grease, as it will stick slip.

wouldnt axle wrap go hand in hand with the driveline angle? Mine shudders only when loaded heavy.
