I would like to know what's happening, it seems as if idling for a minute to let my transmission temperature dial raise past the lowest line on the dial fixes or at least drastically reduces a couple issues.

The truck will deliver power much smoother off the line. I've been concerned about this for a while. The degree to which it happened wasn't constant but it seems like the truck is having trouble grabbing on (so to say) to the power coming off the line. I sort of liken it to a rope. When I give it the beans the rope goes forward but it takes a half a second or so for the truck to "grab" on to the rope. Never hard shifts, it's just delivering the power off the line or from a near stop.

Idling for a minute seems to fix this, power delivery is smooth off the line. Transmission dipstick was nice and pink but smelled slightly burnt. This is with the engine cold overnight. Didn't have time to do multiple wipes or check in the handbook for the proper methods of checking fluid, I just pulled it out quickly to take a look before heading out. Fluid covered the whole tip.

Second issue that seems to be fixed is that the battery light doesn't come on nearly as much and not for nearly as long. Typically the battery light will come on and off seemingly on its own whim during the drive. However, it seems to stay more consistently off if I idle right after startup.

Now bear in mind I baby my truck, I don't rev it high right after startup. Just low enough to cruise around the parking lot until I hit the road then I accelerate up to 40 - 60 depending on my route. I'd gladly give it the minute to warm up in the future but if I could get down to the bottom of this that'd be preferred, I doubt this is required behavior.

I do realize that these issues are not tied to startup behavior but I find it interesting that idling for a minute at startup to let the transmission gauge rise seems to mitigate these symptoms.

Thanks and sorry for the long post!

TL;DR - Idling at startup seems to make my truck deliver power smoother, battery light stays off for more time.

 

I once had a C6 that would back out of the parking spot but would not move forward until the trans warmed up. Sure pissed off the people waiting for me to move.

I think the main issue was the seals had shrunk from being parked most of the time.
I didn't drive it very often.
