Description

Flo-Dynamics 40100148 Full-Size GM Allison 1000 Series Transmission Adapter

PART NO: 40100148

The Flo-Dynamics 40100148 adapter is engineered specifically for full-size GM medium-duty and commercial applications equipped with the Allison 1000 automatic transmission. Designed for trucks such as the GMC TopKick, Chevrolet Kodiak, and certain RV and vocational chassis, this robust block-style adapter replaces the transmission’s cooler-line thermostat housing to provide direct, dual-line access for efficient fluid exchange.

Ideal for use with Flo-Dynamics machines such as the CVAC3 and PSI Cool, it enables high-flow flushing, including reverse operation, and ensures over 90% fluid replacement in minutes. Built for durability and speed, it’s the preferred choice for servicing medium-duty Allison 1000 systems. Note: This adapter will not fit pickup-style Allison 1000 transmissions found in Duramax-equipped Silverado HD and Sierra HD models, which use a smaller snap-in quick-connect cooler housing.
