Mityvac MVA590 GM ATF Refill Adapter for Automatic Transmission Fluid Service

The Mityvac MVA590 GM ATF Refill Adapter is a professional-grade tool designed for servicing automatic transmission fluid systems on late-model General Motors vehicles. This adapter enables precise fluid filling through the transmission's fill port, eliminating guesswork and mess during ATF service procedures.

Key Features:

• High-tolerance zinc-plated steel construction for durability and corrosion resistance
• Comparable to GM special tool DT-47784, providing OEM-equivalent functionality at a lower cost
• Quick-change Mityvac-style coupler for fast, secure connection to Mityvac fluid dispensers
• Compatible with GM models including Avalanche, Cadillac CTS/ATS/CT6, Camaro, Silverado, Sierra, Tahoe, Yukon, Suburban, and other vehicles requiring sealed transmission service

This adapter is essential for properly servicing modern GM transmissions that lack a traditional dipstick and require specialized equipment for fluid level checks and refills. Works seamlessly with Mityvac fluid evacuation and dispensing systems to streamline transmission maintenance procedures.
