SunCoast Allison Deep Filter Lock

The SunCoast Allison Deep Filter Lock is designed to secure the transmission filter in place on Allison 1000 transmissions equipped with a deep transmission pan. Under high line pressure and heavy load conditions, the factory filter can become dislodged, potentially causing fluid starvation and severe transmission damage. This filter lock helps prevent that issue by positively retaining the deep filter during hard use.

Whether your Duramax truck is built for towing, racing, sled pulling, or daily driving, the SunCoast Deep Filter Lock adds an extra layer of protection for your Allison transmission.

Features

• Prevents Allison deep transmission filter from becoming dislodged
• Designed for Allison 1000 transmissions using deep pans
• Helps maintain proper fluid pickup under high pressure conditions
• Ideal for towing, performance, and heavy-duty applications
• Simple installation
• Durable construction for long-term reliability

Why Use a Filter Lock?

High pressure conditions inside the Allison transmission can cause the filter to move or separate from the pump inlet. When this happens, the transmission may lose fluid pickup, leading to slipping, overheating, and possible transmission failure. The SunCoast Deep Filter Lock helps keep the filter securely seated during demanding driving conditions.
