Automatic Transmission Relay for Nissan and Infiniti

Standard Ignition RY-91 is a 12-volt automatic transmission torque converter clutch relay built for vehicles that use a 6-terminal blade-style relay with a female connector. It is specified for 10-amp operation and supports A/C, heating, and defrosting functions in the listed applications.

Compatible With Nissan Maxima, Pathfinder, Sentra, Altima, 240SX, 300ZX, and Infiniti Q45, G20, I30, J30, M30, QX4, FX35, FX45, and more across model years from 1977 through 2007.

  • Standard Ignition RY-91 relay for transmission-related electrical control
  • 12 V relay with 10 A amperage rating
  • Female connector with 1 polygon-shaped connector interface
  • 6 male blade terminals for listed OE-style applications
  • Used in systems serving A/C, heating, and defrosting functions
  • Cross-references Four Seasons 35844 for the same application

Detailed Product Overview

This relay is used in automatic transmission control circuits where torque converter clutch operation depends on a properly functioning electrical relay. Standard Ignition RY-91 is listed across a wide range of Nissan and Infiniti applications, including Nissan Frontier, Pathfinder, Sentra, Xterra, Maxima, and Infiniti Q45, I30, and G20 platforms. The fitment data also includes several OE-numbered and connector-specific applications, such as gray, brown, and Jideco/Niles variants, so matching the connector style and terminal count is important during replacement.

Common Problems This Relay Can Address

  • Torque converter clutch relay failure causing transmission control issues
  • Intermittent electrical operation in A/C, heating, or defrost circuits
  • No-start or no-command conditions related to relay switching
  • Incorrect relay fitment when the original unit uses a 6-blade terminal layout
  • Electrical contact wear in older Nissan and Infiniti relay applications

Installation Notes and Tips

Verify the connector shape, terminal count, and terminal gender before installation. This part does not include mounting hardware or a mounting bracket, and it has no mounting holes. Several fitments require specific relay variants by color, supplier, or production date, including some Nissan Maxima, Pathfinder, Sentra, and Infiniti Q45 applications. Confirm the OE number and connector style against the original relay before replacement.

Quality Assurance

Standard Ignition supplies this relay as a direct-fit electrical replacement for the listed applications. Part number RY-91 is also referenced in interchange data for related aftermarket and OE-style applications, including Rostra Powertrain Controls 60-0091.
