4T40E Shift Kit, remanufactured and ready to install. Fits the 4T40E. Ships fast from the USA.
This 4T40E shift kit is remanufactured and bench-ready, 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 4T40E 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 4T40E and ships from the USA. Confirm your year and application against your own vehicle before installing — the 4T40E ran across several updates, and matching the correct revision is what keeps the shift quality right.
