4l60e accumulator piston pin vs pinless. Use of the Sonnax part eliminates the need for the pins.

4l60e accumulator piston pin vs pinless. While I didn't install a shift kit during my rebuild I'm pretty comfortable saying there's no real change in feel or performance. There was no spring in the 4th accumulator because the 4th gear shift doesn't seem to be very sensitive to spring rate changes. In 200-4R applications, this kit can only be used in the 3-4 accumulator location. Travel in the 1-2 accumulator renders the inner spring <90% functionless. Problems with the 1-2 Accumulator are especially frequent so, if your 1-2 up-shift seems a little sluggish and then Accumulator Parts 1-2 Pinless Accumulator Piston Kit 1-2 Accumulator Inner Spring 1-2 Accumulator Outer Spring 1-2 Accumulator Waved Spring Accumulator Housing Spacer The parts listed here may be protected by one of these patent numbers: 6,619,323 & 6,899,211. In GM 4L60-E, 4L65-E and 4L70-E units it is common to have poor shift quality, burnt bands or clutches due to accumulator piston wear. 4L60E 4L65E 4L70E 700R4 200-4R TRANSMISSION PINLESS 1-2 or 3-4 ACCUMULATOR PISTON KIT, SONNAX 77998-03K. Just a quick video on how to perform this simple modification to your 4L60E. In conclusion, the 4l60e pinless accumulator offers significant advantages over its pin-type counterparts.
