727 Transmission showing signs i need to get it in the shop, need a shop recommendation in Coachella Valley area

I found a tranny shop recommended by Brian, who is a contributing member to the forum. What I found in the mean time is the slippage was probably due to how I was driving it. Putting it in neutral at a stop light was the cause and the slippage was the effect.

I am going with lokar throttle and kickdown linkage as the stock linkage just simply won't work on my 360. Getting it installed next week.
