Hello! Automatic transmissions are notoriously difficult to diagnose, so I would recommend taking it to a specialist that can provide you with a list of parts needed, so you don't end up buying the wrong parts.

Hi Dan, A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied by the transmission computer or controller. If you’re experiencing transmission solenoid troubles, it will become evident in one of four ways: 1. Delayed gear shifting 2. You can’t downshift, and your engine continues to rev even when applying the brakes 3. Your transmission gets stuck in neutral 4. Shifting gears become rough and choppy Still, we recommend referring to your trusted local auto repair shop/certified technician for the troubleshooting and repair.
