Solenoid Valve Kit Selection Guide

Home / Solenoid Valve Kit Selection Guide

Step one: name the functions

List the solenoid functions your job needs: pressure control, shift, lock-up, or a combination of them. A kit inquiry that names its functions can be answered precisely; a kit inquiry that only says solenoids cannot, because the three functions are not interchangeable. If you are unsure which function matches your fault, start from the valve body solenoid page, which sets the three functions side by side.

Step two: kit, single solenoid, or complete assembly

• A single solenoid suits a single identified fault in one function.
• A solenoid valve kit suits several solenoids replaced together, or a workshop stocking the set for repeat work.
• A complete valve body assembly suits a job where the valve body passages or bores are also at fault, or where a complete set with solenoids is required.

Choosing the wrong level is the most expensive selection error: a kit cannot repair a worn bore, and a complete assembly is more than a single solenoid fault needs.

Step three: state the checks the kit must pass

Ask whether bench testing covers the kit solenoids across oil flow, pressure stability, shift response and sealing, and whether the test covers the solenoids alone or fitted in an assembly. State whether gaskets are in scope where the kit is fitted as part of a valve body job, so that the scope is agreed before work starts.

Step four: complete the commercial details

This site does not publish a solenoid valve kit fitment list. Fitment is confirmed from the details you share in the inquiry, not from the kit name alone. Warranty is at least 1 year, and certificates are available upon request.
