A Dedicated Grumman LLV PCM Specialist

Grumman LLV control modules require experience that many general automotive repair facilities may not have.

Solo Auto Electronics has repaired these modules for USPS vehicle maintenance facilities in Florida and other states. That hands-on experience allows us to recognize recurring problems, properly evaluate the original module, and determine whether it can be repaired.

Instead of searching for an often difficult-to-find replacement, send us the original PCM and let a dedicated specialist inspect it.

Why repair the original?
Keep the module your vehicle already knows.

Keeping the original PCM can help avoid the compatibility and availability problems associated with sourcing used or discontinued replacement modules.

Less setup on return
May reduce programming and configuration needs.
