Description
4L80E / 4L85E Shift Lever Kit, Sonnax 38512-03K.
Ideal for GM 4L80-E and 4L85-E custom transmission builds and performance applications. Sonnax shift lever kit 38512-03K makes it easy to install a short-length manual shaft that delivers trouble-free operation with aftermarket shifters.
While the long-length shaft found in ’95-later units is compatible with aftermarket shifters, many prefer converting to the short length found in early units to help with clearance to exhaust systems. Using an early-style, short shaft, however, can cause problems getting the linkage to work properly in all gear ranges from Park to Low. This is due to the early-style shaft’s flat indexing that cause it to operate at different angles than the late-style, long shafts.
Installing Sonnax 38512-03K lets you overcome this problem with a hybrid design that combines a short shaft length with the indexing angles of a late-style shaft. Sonnax configured this unique upgrade to work with the ’95-later detent rooster comb. This features a square identification hole and .316″ wide internal flats. The kit can be retrofitted into early 4L80-E units, but requires using a ’95-later detent rooster comb.
