Sonnax pinless accumulator pistons

I'm putting the Trans Go 700 kit into my 700r4 trans because of a stuck TV valve situation. Does anyone know if the Sonnax pinless accumulator pistons will affect the kit's performance? Thanks

I've been running Sonnax pinless pistons in all 3 accumulators of my 4l60e for a few months now. 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. They're really just a preventative measure to avoid a pressure leak from worn pin bores. IMO great insurance for the money spent, especially if you're already in there
