What It Helps Address

• Erratic or delayed transmission shift timing
• Incorrect vehicle speed signal to the transmission control system
• Transmission-related warning lights or speed sensor fault codes
• Harsh, inconsistent, or unstable shifting behavior
• Loss of speed input data after sensor failure

Installation Notes

Many listed applications require valve body removal for replacement, so confirm service access before beginning the repair. Verify connector style, terminal count, and vehicle application against the original part before installation. Because mounting hardware and wiring harness are not included, reuse or source the required vehicle-specific components as needed.
