1992 Mitsubishi Diamante Hard down shift into first gear

Hi Paul,

Thank you for the donation.

Harsh shifting are usually caused by inconsistent solenoid operations and most probably the rebuild people would replace the solenoids for you to rectify the problem.

Apart from the solenoids, it sometimes is caused by the brake band and readjustment is necessary.

Worse case scenario is a leaking line pressue caused by worn bushings or mainshaft bearing/sealing ring seats and that would require stripping the trans all over again.

A loose sensor connection or faulty sensor would also cause the problem and the rebuild people would have to do a diagnostic to verify this.
