I took my car to the local Mitsu dealer (bunch of dishonest crooks) for diagnostics. They say the trans computer is out. Well the trans is in limp mode sometimes and shifts perfectly other times. It comes and goes. I never thought that a computer could work sometimes and not other times. I figured if it was broken, it would never work again. Is it really my computer that is damaged? I pulled it, and it didn't appear damaged just from a visual inspection, but that doesn't tell me much. I am suspicious because they also said the IAC was broken and was responsible for my car dying at idle. I replaced it with a brand new one and problem persisted. Spent $300 for nothing (100 for diag, 200 for IAC). Someone please help me out.
