Sonnax 3-4 Accumulator Spring Update

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



A518 / 46RH / 46RE

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.

When broken, there will be complete or intermittent loss of overdrive.
No 3rd to 4th shift

This is a suggested replacement every 50,000 miles during fluid service , and band adjustment.

This is sold as pictured

Thank you again for all your help. It's a good thing I ordered the Sonnax spring. Mine was broken in half! Again, thank you so much for your excellent service and quick shipping (from the west coast no less). You've earned a repeat customer, 100%.
