700R4 Accumulator Valve Train Kit
Sonnax Update With Selective Shift Valve Return Springs

Severe wear in the Accumulator Valve bore is very common in these models.
This wear causes a variety of issues related to Accumulator pressure loss.
This pressure loss causes a Harsh 1-2 Shift.
Additionally it causes the 2-4 band to agressively wear reducing its longevity.

Sonnex has Engineered a wear resistant sleeve and valve kit.

This valve train has multiple OE size variations, including B, A, N, M, L, K, and F.
The size variations are clearly stamped with the letter on the aluminum sleeve.

This kit will fit letters M, L, and K.
These letters will fit most vehicles, but depends on engine size and model.

Symtoms This May Fix

1-2 Bang at light throttle
Reduced 2-4 band life

This Kit Includes

Springs (3) Selective
