TODAY is a Great Day to visit our Store and order the parts you need for your truck!
Sounds like you have a fuel starvation issue. As far as the trans goes, do you have the detent cable hooked up and properly adjusted? How about the vacuum modulator? Have you ever replaced it or adjusted it?
I'm not that hep on modulators except when they leak and you start sucking ATF down the intake and the resultant blowing of white smoke. Do a search on modulators here, I think I saw recently a post about when and how they come into play.
Have a great weekend! Oh, and when did your Llama die?
