the other day i went to take off from a light and my truck hesitated then jerked . i took it in to the dealer yesterday. the looked at it and said that my PCM had to be reprogrammed. that if was starting off in second gear. he also said that i had 7 updates for my transmission. is that like a trouble code? and does it do that because it electronic? can anybody explain that it to me? its fixed now .. iwas jus curious.
