I bought a 2003 Mitsubishi Diamante LS. (Mitsubishi never again!!!) I repaired the "infamous" heater core leak myself at about 70K miles. Now, at 82K miles, the transmission is acting up. It very slowly engages into reverse and won't engage into drive unless you give it some gas. Took it to a transmission shop 7 weeks ago. Installed a used transmission and it didn't work. Rebuilt my original transmission and still does the same thing. I asked if it was the transmission control unit (TCU). The transmission tech says the 2003 year model did not have a TCU. He said it is all contained in the Powertrain Control Module (PCM). The PCM seems to be working fine. We can't figure out what's wrong, and my transmission tech and I are getting very frustrated. Any help would be appreciated.
