Ram Transmission Shift Solenoid

Choosing A Transmission Shift Solenoid

A transmission shift solenoid must match the automatic transmission and the hydraulic circuit it controls. Compare the transmission identification, solenoid position and electrical connection rather than choosing by vehicle name alone. Parts may be sold individually, in a set or as a larger control assembly.

A-Premium offers different solenoid configurations for selected applications. The number of terminals and the mounting arrangement vary between parts, so the package and the assigned position need to match the repair.

How A Shift Solenoid Works

The transmission controller commands solenoids that affect fluid flow through the valve body. Hydraulic pressure then operates the components used to select gear ratios. Different solenoids can perform different functions, including shift control, pressure control or torque-converter control.

The solenoid is one part of a larger hydraulic and electrical system. A replacement should match its designated job within the transmission rather than being treated as an interchangeable valve.

Diagnosing A Transmission Solenoid Problem

Delayed, harsh or unexpected shifts can involve a solenoid, but the symptom alone does not identify the failed part. Fluid condition, wiring, a connector fault or another hydraulic problem may also affect operation. Use the transmission's service procedure to determine which components need attention.
