No Prob. Welcome to the site.

 

If you look to your left at the top, you will see a link to the RPO codes. Go to your year, and truck. And it will show you what all those codes mean in your glove box. So you can find out exactly what came in your truck.

All late model trucks with 4.3, 4.8, or 5.3 liter engine have a 4L60 transmission.
