So the dealer test drove the vehicle, and felt the slight shudder, but the pico did not pick it up...So they didn't do anything for my 6 speed.
The tech was saying the updated fluid was only for the 8 speeds. Is this correct?
They mentioned that I should just keep driving it until it gets worse, then they will try again for the TSB...they're very cooperative and trying to help, but the pico needs to pick up the shudder in order for the work to be covered under warranty, which makes sense.
Part of me wants to get the fluid flushed / pan dropped and filter changed, get a tune done, and be done with it. The truck has 53k on it, I towed a 22' 6k trailer 2000 miles when the truck was only had 6000 miles on it, so that's why I'd like to get the fluid changed out.
The shudder happens more when its cold out and the trans temp is around 150 deg. Sometimes it happens severely in the middle of a long trip but its almost impossible to duplicate when the pico is hooked up. It happens more with the stock rim/tires (which I had on for the dealer visit), but it does not happen as badly with the 33" tires and rims...they're larger and heavier, so the trans is less likely to stay in the shudder sweet spot. It'll downshift earlier or stay locked up, and my fuel mileage obviously pays for it.
Thoughts? Am I making a big deal out of nothing?
Thanks
Mike
