Question about 1999 GMC Suburban
I have a 1993 K1500. I had the transmission rebuilt in 2007. Shortly after the rebuild. It started changing gears really hard from 1st to 2nd when it is first cranked up. After you drive it for about 10 mins. It changes smoothly until you cut the truck off, and let it sit for awhile. Then it changes hard again for about 10 mins the next time you crank it up. The place that rebuilt it says it is not the transmission, but could be a mapping sensor controling the idle speed.
The computer is puting trans in safe mode. Converter valve bore is worn out in valve body, an oversize valve is avalible, find a shop that can do the repair.
