Once again, thanks guys for ALL the info. I will defintiely weigh all of my options...I have emailed SMR (have not heard back from them yet) I do not know how to get a hold of the guy with turbo 4L80, if anyone does, PLEASE let me know, I also sent an email to the transmissioncenter.net guys, and am sending one to Lentech. Once I gather all of the info I need, I can then base my decision on that. I would like to stay with the 518, but it all comes down to customer service, product, and then $$$$$$$. I will weigh them all and see what best fits me. The fab work is least on my mind. I want the best tranny with the best customer service, and if that means I have to pay a little extra $$$$$ and do some extra fab work, then so be it. Keep the info/suggestions coming....




ANYONE KNOW THE GUY WITH THE TURBO 4L80 CHALLENGER???????????
