2007 Tahoe Transmission

Over the weekend I serviced the tranny. Now, first gear slips when you go to take off. It only happens once a day. I know the pan was a little pain to take off. I don't know if I messed anything up. It's actually at the shop now to check it out tomorrow but I wanted to know some opinions. It's has 100000 miles and yes, the fluid is full.

How does 1st slip? My truck falls into second gear lazily when on light throttle and it could be considered a slip but it's actually changing gears into second. It just started doing this recently and I was going to ask Justin to check my tune when he is in my town. If this is what your feeling drop it into M and see what gear your actually in.

Manually shift it.

What was the fluid condition?

The old fluid was dark. It was changes at 50000 miles I guess. At least that what carfax says.

When you switch it to drive from whatever gear, rpms climb and it doesn't move then slips into gear very sloppy.
