Sonnax 3-4 Accumulator Spring Update

This fits all below models of Chrysler /Dodge/Jeep Automatic Transmissions:

A618 / 47RH / 47RE
This was created due to the high failure rates of the original OEM design. 

This Sonnax update will restore proper shift feel and eliminate sluggish overdrive engagement.

About 60%-70% of the factory springs were .063" thick spring stock.

This design is .126" Thick

It is extremely common for these to become worn out and fatigued even on moderate mileage units.
Most models that completely lose overdrive , have a broken 3-4 Accumulator Spring.

Sonnax spring is a duplicate of the 47-RE diesel application.
