So I bought my first sidekick this last winter and I never really went to fast before but now the the days are getting warmer I feel the need to go fast. The only thing stopping me is what I think my tranny is. It's all organically and I just put 200k on it. First gear it gets to me to about 15 at about 4k. 2nd is to 25 at 3k. 3rd gets me to about 35 at 3.5k 4th gets me to 45 at about 3k and fifth I'm kickin 3k at 55. Does anyone know how to fix it? Or would I be better off getting a new tranny?
