Transgo 4l60e-hd2-c The directions specify to drill numerous holes to .093. On a tranny builders advice , I drilled 4 of the hole closest to the top of the directions to .110 or a 7/64 I used 1 spacer in the 1/2 accumulator .I did a yank 3000 and a servo as well. I could not be happier. It will bark second under full thottle but ,light thottle shifts are ok with me. They may be to harsh for some.There was no need for washers on the servo as the band was very tight after replacing the 2 4 band. Hope this helps.traction is my biggest problem now.

 

Ok Thanks Man. Appreciate The Info.
