Description

The Rostra Precision Controls 350-9000 is an automatic transmission wiring harness kit designed as a direct replacement for GM vehicles. This kit specifically fits the 4L80E transmission model for model years 1991 through 2003. It includes an internal wiring harness, which features a built-in fluid temperature sensor, and an external wiring harness pigtail with 15-inch leads. For 1991-1992 applications, the included external harness must be changed (using Rostra # 350-0033) to ensure proper compatibility. The product is noted for its OE quality, being sourced by professional transmission shops.
