Hey guys, Alright a couple months back my A/C accesory belt on my 99 Silverado 5.3L snapped, and I only replaced it this friday. BUT.... now after replacing the accessory belt and reinstalling the serpentine belt my truck is acting funky! Now when I start the truck and put it into drive you can feel the transmission hard shift into gear. Then when you push the accelerator the truck hesitates, goes, hesitates, then finally goes and when it shifts into second you can really feel the hard shift. Then from 2-3 it does the same thing and almost feels as if it doesn't even shift into third. I haven't gotten a chance to read the engine code and I will do that tonight and repost later. I was hoping someone would be able to suggest something off of that. I really can not afford a major repair right now so (im being a dreamer) and hoping it is a quick fix! Let me know anything you can suggest and I will repost later tonight the codes that I get. Thanks!
