Sonnax® Oversized Accumulator Pin

4T60 4T60E

GM Chevy Buick Cadillac Oldsmobile Pontiac 1991-2011

Fits 1-2 & 2-3 ONLY!

 

GM 4T60 and 4T60-E units commonly display negative shift characteristics that can be traced to excess wear at the 1-2 and 2-3 accumulator piston pin bores. Slipping, flares, and soft or inconsistent shifts often result, followed by burnt 2nd and 3rd clutches. Extreme cases will cause a loss of 2nd, 3rd and/or 4th Gears. Restore hydraulic control and banish sloppy shifting by reconditioning the pin bore and installing Sonnax® oversized accumulator pin 84573-01K.
