With a maximum operating pressure of 16.0 bar and a temperature range of -25°C to +100°C, this valve provides precise control and enhanced durability for demanding applications.

Key Features & Benefits

This valve basically regulates the hydraulic pressure within your automatic transmission. It manages the flow of transmission fluid to different parts of the gearbox – things like clutches and bands – to make smooth gear changes happen. It's not a simple on/off thing, it adjusts constantly based on how you’re driving, speed, and load on the engine. It’s got a little spool inside that moves to allow more or less fluid through. Think of it as the brain telling the transmission how to shift. It’s part of a larger system, but it's a key component. It receives signals from the transmission control module – the TCM – and uses that info to direct fluid pressure. Without it working right, the gearbox just won't be able to select the correct gear at the right time, or it might slip. It’s definitely tucked away inside the transmission itself, so it's not something you'd normally see.

Symptoms, Risks & Replacements

A failing pressure control valve is a big deal. It can cause all sorts of issues. You’ll notice if it's going bad, usually with harsh or erratic shifting. Sometimes it'll feel like it’s slipping, or that the transmission is hunting for the right gear. In severe cases, it can lead to complete transmission failure. It acts like a shield protecting the delicate internal components from damage. It’s a relatively small part, but it has a massive impact. You can usually find a good replacement part on sites like Fixparts Online – they carry a pretty wide range of transmission components. Getting a new one installed promptly will save you a lot of trouble and potentially a very expensive transmission rebuild down the line.
