This tranny does NOT need special parts it needs a competent assembler and those are far and few between. You wouldn't believe how many stock parts are in my nearly 8yo 4L60E, heavy car making more than average power and it holds up great.
They have problems because factory tolerances were broad, they were setup to shift grannylike and raging incompetents like to tell folks it is the trannies fault instead of their own when they build them badly.
A few key phrases and suggestions to run from would be things like kevlar, blocked accumulation, billet servos(on anything but a big power car), 13-vane pump in a 10-vane tranny. Claims that a 5-pinion planetary is necessary should be considered suspicious at least, the 4-pinion from this era of 4L60/4L60E was never weak when GM made a cheaper manufacturing decision to do 5 powdered metal pinions instead of the 4 FORGED everyone jumped on the bandwagon for no good reason. Good builders know the 4-pinion wasn't a problem but might still offer a GM specifically 5-pinion as an option. The blind will to have 5-pinion spawned cheap junk chinese knockoffs which are much weaker and troublesome.
They might suggest a BEAST sunshell, they are decent but unbalanced, still have a stocker in my car, long as the shift firmess is set appropriately they are usually just fine. If you want or get neck snapping shifts it will break things, quick shifts are what is needed.
Far as a tune I believe one of the guys from pcmperformance (add a dot com to that) lives in Long Island.
Far as who to do the tranny work maybe contact the Long Island Impala SS club and see who they recommend. I like the guy that did mine but I shipped the tranny to California to have it done right after a local completely botched it.
