A-Premium Automatic Transmission Shift Control Solenoid Block Pack for A604 — 8-Pin Connector, Gasket Included

The A-Premium Automatic Transmission Shift Control Solenoid Block Pack is a direct-fit replacement kit designed to restore electronic shift control on A604 transmissions for select Chrysler, Dodge, Plymouth and related models.

This solenoid block pack replaces worn or failed shift control components so your automatic transmission can re-establish reliable gear selection and electronic modulation. The kit includes the solenoid block with the correct 8-pin terminal connector and a new gasket, and matches factory reference numbers for straightforward installation on many late-80s through 2019 vehicles that use the A604 transmission family.

How does this solenoid pack improve transmission operation?

Replacing a failing shift control solenoid block restores precise electronic control of shift timing and pressure modulation without replacing the entire valve body. That helps the transmission find correct gear ranges, reduces erratic shifting, and eliminates many common electronic shift faults when the solenoid block is the root cause.

• Restores electronic actuation for the A604 transmission
• Reduces symptoms like harsh or delayed upshifts and limp mode triggers
• Direct replacement with matching connector and terminal count for plug-and-play installation

What’s included and what are the technical specs?

The kit ships complete with the solenoid block, an OEM-style gasket, and a single 8-pin connector preconfigured for the A604 valve body. Technical details are presented to help confirm compatibility before purchase.

• Gasket/seal: included to ensure proper valve body sealing
• Transmission model compatibility: A604 series
• Electrical connections: one connector with eight terminals/pins for factory wiring harness compatibility
• Cross-reference numbers: 698-100, 4504570, 5015646AB/AC, 5140429AA to match OEM parts lists

How difficult is installation and what should I prepare for?

Installation requires moderate mechanical skill and basic tools; a lift or jack stands, drain pan, and torque wrench are recommended. Removing the transmission pan and valve body access is typically necessary, so plan for a clean workspace and follow torque and gasket replacement guidelines to avoid leaks.

• Expect valve body access—plan 2–4 hours for an experienced DIYer
• Replace the gasket and use correct torque specs to prevent fluid leaks
• Verify electrical connector seating and inspect wiring for damage before reassembly

Who is this for: The A-Premium Automatic Transmission Shift Control Solenoid Block Pack is made for owners and technicians restoring electronic shift control on A604-equipped vehicles. It suits DIY mechanics comfortable with valve body access, independent garages needing a direct-fit replacement, and fleet managers seeking a cost-effective way to address common shift control failures. Backed by A-Premium’s one-year unlimited-mileage guarantee, it’s a practical replacement option when the solenoid block and connector are confirmed as the cause of shifting issues.
