4L70E Pinless Forward Accumulator Piston Kit


This fits all below models of GM Automatic Transmissions:
 
4L70E / 4L75E


Late engagement and Slips are just a few problems caused by accumulator piston ware.
Over time the reciprecating motion of the piston causes ware in the piston pin bore.
Once the piston pin bore ware gets bad enough it can cause severe fluid pressure loss.

Additionaly the Shallow profile of the piston can cause the piston to become cocked and score the piston bore.


Sonnax Fixed this with the Pinless Forward Accumulator Piston.

Its Pinless Design eleminates the possibility of piston pin bore ware.
Its additional length adds stability and prevents the piston from becoming cocked and scoring the bore.
Sonnax also uses dual sealing rings for optimal sealing and shift quality.
The dual sealing rings greatly improve the longevity of the piston and protects the bore.

This Sonnax Accumulator Piston is Billet Aluminium and is Engineered for Heavy Duty Applications.



In this 5 piece kit you will receive

1 Pinless Accumulator Piston
1 D-Ring
1 Teflon Sealing Ring PTFE

2 Steel Balls
