Dynotech can build a 4L60E with the best of 'em.
And as far as "pricing" goes...well, ya get what ya pay for in this world. Is Dynotech cheap? No. Is Dynotech competitive? Yes. Does Dynotech give awesome customer service before, during, and after the sale? HELL YEAH!
Nothing against the "chain" transmission places, but I'd rather deal with a place where the owner is the guy cracking my tranny open. That way there is no one else to answer for the work. Eric is friggin' awesome...I can tell many stories, but here is one for ya:
I couldn't get my friggin' T-Type to start. I was pretty sure something was FUBAR in my computer, but didn't know how to check things. I went to pick Eric's brain, and he stopped what he was doing to listen to me. He then loaned me one of his "test" computers and "test" chips, and told me to install them and see waht happens. I installed his computer, and the car fired right up! I took his computer back ASAP, and asked him what I owed him. He said "Nada!" He didn't even want me to buy him lunch. He said he was happy to be able top help me out. So, needless to say, Dynotech is tops in my book!
