Product Details

Sonnax billet aluminum, pinless accumulator piston set

Fits the 4L60E, 4L65E, 4L70E, and 4L75E

1992-up

This kit comes with the following parts:

• Sonnax 77987-01K forward piston
• Sonnax 77998-03K 1-2 & 3-4 piston (Qty 2)

The 4L60E and its variants were in production from 1992-2013 and can be identified by the square 16 bolt oil pan and 4 forward gears.  1992-1993 are cross-over years, so your vehicle could have the earlier non-electronic transmission instead.  If unsure of your model, the 4L60E can be differentiated by looking at the wire plug going into the transmission. The non-electric shift will have a square wire plug with 2-4 wires. The 4L60E will have a round plug with 11 wires.

The 4L60-E was found in the full range of General Motors vehicles including, Buick, Cadillac, Chevrolet, GMC, Hummer, Isuzu, Oldsmobile, Pontiac, and SAAB.

These transmissions can be found in the following vehicles; however you should double check your application with the 16 bolt pan count. It is common for similar vehicles to have multiple transmission options available from the factory.
