Candidate cause (the documents say what to do)

4L60-E burnt 3-4 clutch pack

Low line pressure and/or leaks of 3rd gear oil are the root cause of most 3-4 slipping.

Small leaks at several points in the circuit can add up to enough pressure loss to allow slipping.

What to do

  1. Test the 3rd accumulator checkball capsule for leakage; a leaking capsule is a leading cause of 3-4 clutch failure.
  2. Whenever a burnt clutch pack is found, inspect all three circuits methodically to find and eliminate all leaks.
  3. Thicker heavy-duty backing plates that eliminate clutch pack flex are available in the aftermarket.

Caution: An obvious leak such as a cracked apply piston should not stop further investigation.

Passages of the technical documents

  • Burnt 3-4 clutch packs are notoriously common in the GM 4L60/E family of transmissions.

  • Low line pressure and/or leaks of 3rd Gear oil are the root cause of most 3-4 slipping.

  • even small leaks at a few junctions along the way can add up to a big enough pressure loss to allow slipping.

    Sonnax 2018-06-06

  • The weak OE 3-4 backing plate flexes during application, allowing heat to build up unevenly within the clutch pack’s limited space.
