Transmission shop near San Antonio

[blackhawck]

Hello all. I'm in need of a reputable transmission shop in the San Antonio area. We live in Bulverde so anywhere near SA or New Braunfels would be great. I have a 71 K10 with TH350 an NP205 that leaks like a sieve. I have dealt with it until now as the transmission shifts fine, however I am working out of the country for 4-5 months at a time. My wife occasionally drives the truck and is good about checking the fluid level but I would rather her not have any issues with it. I need a reputable shop that will not see her come in with the truck and see dollar signs. Also looking at having a vintage air system installed. Thanks in advance for any recommendations.
