I bought a 2005 Chevrolet Colorado 2WD last July. I've put about 11,000 miles on it for a grand total of just under $7,500 not including gas. I have noticed that my transmission takes a second or two to engage when shifting to Drive, or Reverse. I do not know how much this costs to fix, how serious of a problem this is, or if this is a problem that will get worse over time. I put the truck up on craigslist and met with someone who offered me $6,500. What do you think I should do, sell or keep? Best answer to most helpful response.
