1990 Mitsubishi Eclipse ProblemsManual Transmission Shifting Difficulty
The manual transmission may become difficult to shift, this is commonly caused by binding between the synchronizer and the gear surface. Adding a special friction modifier to the manual transmission fluid will often correct this condition. If the problem persists revised synchronizer kits may be available.
The Check Engine Light may illuminate due to one or more engine vacuum leaks. Our technicians tell us these leaks can be caused by damage to seals and/or vacuum hoses as a result of to much ethanol content in the gasoline. Affected hoses and seals must be replaced to correct this concern.
The door glass may be hard to roll up and/or come out of the run channel. Our technicians tell us the repair can include adjustment of the run channel, regulator to glass, regulator to door, and if necessary shimming of the window regulator.
