How to install Pin-less Accumulator Pistons in your 4L60E

Just a quick video on how to perform this simple modification to your 4L60E. Problems with the 1-2 Accumulator are especially frequent so, if your 1-2 up-shift seems a little sluggish and then, goes in with a bang, this may be the solution. *** PLEASE NOTE, AT 2:45, I MISSPOKE ... THE FORWARD ACCUMULATOR IS **NOT** A BLIND HOLE AND THE PINHOLE MUST BE PLUGGED *** Hope this helps and, if you want to see the entire rebuild process, look up Episode 5 in my "How to LS swap your BMW 650i" playlist!
