Part Summary:
The Sonnax Performance accumulator spring provides firmer shifts for the enthusiast who appreciates quick, positive shift feel.
The spring design provides performance shift feel but does not reduce accumulator piston travel.
This allows for a firmer but still cushioned shift that minimizes shock to the band and shafts.
Sonnax now offers an enhanced performance spring for use in the Valve Body accumulator.
The Sonnax spring may be used to replace the stock spring to
achieve a firmer shift and prevent the “thunk” sound during shift. The Sonnax spring
achieves the same effect as the common shop practice of replacing the stock 1-2 accumulator
spring with the THM 350 direct accumulator piston spring. Sonnax spring may also be
used as a replacement for the THM-350 direct accumulator piston spring.
Installation Instructions:
1. Remove the accumulator piston spring and replace with Sonnax spring.
Please Note: Sometimes These Springs Do Not Come Completely Painted And The Ends Will Have Machining Marks On Them From The Manufacturing Process. Also They Will Have A Protective Coating On Them To Prevent Corrosion But These Are 100% New Springs.
