3rd Accumulator Sleeve Kit

SLEEVE KIT 3-4 ACCUMULATOR 700/4L60E

Symptoms:

  • Case damage
  • Scored accumulator bores
  • Worn accumulator bores

Cause:
Repeated oscillation of the accumulator piston scores the 3-4 accumulator bore during normal operation.

Correction:
Sonnax 3-4 accumulator sleeve kit comes with an aluminum sleeve, a replacement piston with an O-ring, and a new accumulator pin. It is compatible with all OE accumulator springs.


The 3-4 accumulator bore on GM 4L60 and 4L60-E series cases can become scored, resulting in the loss of 4th servo feed and 4th accumulator pressure. Scoring is caused by repeated oscillation of the accumulator piston within the bore during normal operation. Once this bore is damaged, the case must be scrapped. The sonnax 3-4 accumulator sleeve kit counteracts bore wear and features upgraded materials for greater urability. The kit's piston is compatible with all OE accumulator springs.

  • Sleeve is manufactured from wear-resistant aluminum
