So i was driving on the highway the other day and my truck was doing fine but after i went off the off ramp and stopped at a stop light. so the light turns green and i do nothing but rev. so i shift back to 1st gear it kicks really hard then it drives again. so then on my way back home after i get off the highway and i test it again before i stop up traffic.... yep did it again....ive had this happen before but i think it only happens after driving highway... i drive a 3L V6 and 2WD Auto....please i need some advice thats CHEAP... ya i'm not much for money

 

i checked it and it seemed fine but i think i might try changing it anyways
