Sonnax 38511-03K, 4L80E Manual Shift Shaft Kit

The Sonnax Shift Shaft Kit 38511-03K for the GM 4L80-E is an early model ’91-’94 manual shift shaft that can be retrofitted to a late-model ’95-later manual shaft detent lever, allowing the late-model case and detent lever to be used in earlier models. This allows rebuilders to convert late-model cores into early-model units. This kit is more cost-effective than the original manual shift shaft and detent lever kit. Without the cost of additional components such as the OEM lever, pin, and shaft seal. These components are rarely used during the rebuild. The manual shift shaft and fasteners are yellow zinc coated to resist corrosion from road salt and other environmental contaminants. The flange face of the nuts is serrated for increased grip.
