700R4 Sonnax Smart Shell Heavy Duty Upgrade


This fits all below models of GM Automatic Transmissions:
 
700R4 / TH700R4

The Factory Design has a Very High Failure Rate.
This is one of the primary one failure point is spline damage.
The splines will beat out and become sharp, in extreme cases even strip out completely.

Sonnax has adressed this and other failure points of the rear planet section of the Geartrain.
They have done this by engineering a special bearing and roller clutch race.
These custom parts redirect the thrust away from the shell splines and onto the planet carrier
.

This shell has heat treated splines, as well as the hardened lugs that engage the drum, to avoid flaring.

In this 3 piece kit you will receive

1 Sonnax Smart Shell
1 Sonnax Engineered Bearing
1 Roller Clutch Race
