Troubleshooting Automatic Transmissions

NO FORWARD – Serious transmission failure in almost all cases

NO UPSHIFT – Less serious, as in vacuum related, throttle cable or governor.

NOISE IN LOWER GEARS – Difficult diagnosis, can be anything from gears to a bad transmission mount (insulator).

HARD SHIFTING – Usually less serious, in nature such as vacuum or throttle adjustment.

SOFT SHIFTING – Late and soft shifting is not a good thing. Early signs of soft or slipping shifts become normal when adjusted upward.

NOISE IN UPPER GEARS – Very hard to diagnose, usually outside of the transmission itself.
