Odd Transmission Problems

[wfoondirt]

I have a 2000 silverado 5.3, 170,xxx miles. After my recent transmission service (fluid/filter) the truck will not take off from a stop correctly in drive or 3rd. It will move and slowly accelerate until about 10mph than it will drive normal. If I shift down into 1st or 2nd it will take off normally and once i hit about 10-15mph I can put it in drive and it will drive normal until the next stop.

I removed the pan and check for loose/disconnected wires and found nothing out of the ordinary.

Any suggestions?

Welcome to AF. May be in default which is a 3rd gear start, have the trans scanned on a trans function scanner for slippage errors and solenoid functions.

Thanks. That is what it feels like, its in too high of a gear when I take off. I will get it scanned next time I get to town.
