Mitsubishi has published technical service bulletins (TSBs) concerning transmission problems with its 1992 3000GT. The transmission problems have caused the jerking during shifting; transmission linkage failure, delay or hesitation when shifting gears; or complete transmission failure. None of these transmission problems have led to any recalls from the manufacturer.
Transmission Linkage Problems
The transmission linkage enables you to switch gears in the transmission of your 3000GT. Linkage failure causes the Mitsubishi to jerk during shifting or lose gears completely. Once this linkage problem occurs, you must take your Mitsubishi to a qualified technician to prevent further damage to the transmission.
Some owners of the 1992 3000GT have reported delayed shifting between second and third gear, as well as third and fourth gear. The transmission in the Mitsubishi will begin to lose power and hesitate before catching the next gear. No specific cause has been attributed to this delayed shifting problem, but according to the TSB, it may require an adjustment in the automatic transmission clutch end.
Manual Transmission Difficult to Shift
The manual transmission in the 1992 3000GT has been the subject of reports about the gears becoming difficult to shift. You may have to jerk the manual gear shift or push it harshly in order for the gears in the transmission to shift. This transmission problem creates an accident hazard by slowing down or stalling the Mitsubishi during normal driving conditions.
Drive Train Failure
The 1992 Mitsubishi can have transmission problems on the all-wheel drive 3000GT because of mismatched tires. The mismatched tires cause the front and back drive train of the transmission to fight against each other. This fighting of the front and back tires causes the transmission to bind, eventually causing the transmission to fail.
