Hi Guys, been doing some searching but none of the other transmissions problems seem to match mine exactly, if you can even call it a problem. When my transmission is cold, below 70*, it tends to slam into gears, 1 through 3 particularly, however when warm it operates virtually flawlessly. I've reduced some of this by being extremely easy on the throttle till it gets to about 90* where it isn't so bad. Was just wondering if this was a normal characteristic of these new transmissions or if mines sensitive to the cold?
p.s. I did happen to notice on one occasion that when I had the key in the run position but the engine wasn't running that the gauge showed the transmission was -16* when it was 70* out, but it read normal as soon as i started the truck, just figured it didn't update when the truck wasn't running, but maybe not?
The hard shifting when cold was always something I thought was normal, mine always did the same thing. I think it has to do with the engine warmup strategy because it forced the engine to operate at higher RPMs and then it would shift hard into the next highest gear. Never seen the -16° tranny temp though, mine was always within a few degrees of ambient after a cold soak.
My 2012 does the same thing. This questions pops up a lot. Im not sure what the colder than lets say 60* has to do with it. It seems to shift snappier, like my 6.0L with a Spartan Tune. Then it shifts normally after a a couple miles or so.
