I'm looking into doing the valve body upgrade on my 99 4runner with a S/C.

1st question: Of those of you who have done this upgrade, did you notice any problems with the upgrade?

2nd question: Is the shifting really hard after the upgrade (will this cause slippage on slick surfaces while accelerating-like going uphill on snow, etc...)?

3rd question: Is there any tranny shop in the Denver area that does these upgrades (I'd rather not have to send my valve body out)?

Thanks everybody.
