Frequently Asked Questions

What does a high circuit mean?

A high circuit indicates the signal voltage exceeds the maximum expected value, usually from an open wire or disconnected component.

Is this safe to ignore?

No. High circuit readings can cause the TCM to make incorrect decisions, potentially leading to harsh shifts or transmission damage.

How long does this repair take?

Wiring and connector repairs typically take 1-3 hours. Internal component replacement may require 4-8 hours including transmission removal.
