4L85E Shift Kit 1991-09

This 4L85E shift kit for 1991-09 is new, so when the unit in your transmission is worn out you install a known-good part instead of chasing the failure piece by piece. In the 4L85E the shift kit recalibrates valve-body pressures for firmer, more durable shifts, and a tired one shows up as soft or flaring shifts and premature clutch wear.

It fits the 4L85E for 1991-09 and ships from the USA. Confirm your year and application against your own vehicle before installing — the 4L85E ran across several updates, and matching the correct revision is what keeps the shift quality right.
