GM 4L60-E, 4L65-E, 4L70-E, 4L80E-, 4L85-E transmissions have both early- and late-style EPC solenoids. The early-style (’92-’02) proved to be more reliable than the late (’03-later), but different pin/connector configurations prevented the use of early solenoids in late units. Sonnax EPC solenoid harness adapter 34435-01K allows plug-and-play installation of early-style solenoids into late-style units.
