8L90-ACCUM

Drop-in fix for worn 1-3-5-6-7 accumulator circuit

This 1-3-5-6-7 Accumulator Piston Kit upgrades the accumulator circuit with a hard-anodized aluminum piston fitted with a PTFE sealing ring. PTFE conforms better to irregularities, including bores worn slightly oval. PTFE is also more tolerant of bore glazing and uneven wear that can quickly damage or compromise a rubber seal.

Also included is a calibrated OE-style ovate wire spring. The TransGo spring design matches the factory spring style maintaining the intended accumulator action while reducing spring stress for a durable, lasting repair.

Corrects/Prevents/Reduces:

• Delayed forward engagement
  Poor shift quality
  2-3 and 4-5 upshift or downshift complaints
  Burnt 1-3-5-6-7 frictions
