Well, have started the pricing game. transmissioncenter wants like $4500 for their 4L80 (have to check email to verify) TCI has their prices listed on their website. They do not however tell you how much power their tranny will take. Their 4L80 goes for $3303.08, plus you have to buy the controller which goes for $874.26. They also have the A518 92-95 models for $2590.75. No one else that I have called or emailed has returned my call, or responded to my email as of yet. I am still waiting to hear from SMR, Lentech, apsprecision.com, sd-concepts.com. So I will give updayes when I hear from these guys....
