99 Yukon transgo sk-4l60e shift kit install

Just received the transgo sk-4l60e install kit in the mail and plan to work on it once the corvette servo and alum piston arrive next week. My question is that some say not to touch the accumulator components. Is that just in reference to the 1-2 accum or it plus the 4th accum? The main goal i'm looking for is the ISO-CONV Valve that eliminates the OD rpm oscillation of 200 RPM while in OD or 3rd gear. Any feed back or tips would be great.

Well on my way to installing this kit. Ordered the pin-less accumulators for the 3 and 4 accumulators to replace the plastic ones. waiting on the numbered drill kit to arrive for drilling the separator plate. I have been doing a video and will edit it and post up when completed.

Okay all done with the kit, so far I'm pleased with the results. The 1-2 shift is firm at all rpm shifts. When WOT it will toss you to the back of the seat. I would probably leave it the stock hole size if I ever did it again. Here is the link to the video I made. Hope it's useful for someone wanting an idea of the standard 4l60E transgo shift kit. This is not the HD kit. Just a video to view follow all your instructions that come with the components you bought.
