Ideas On A Better Auto transmission?

[BBowers]

I am looking to upgrade my stock 48RE. My 4x4 2003 HO has been a joy to own, but I am now addicted to going down the track periodically with my foot on the floor. I want to upgrade my transmission to pave the way for rock solid reliability doing 98% normal driving with occasionally towing my 5000 lb boat/trailer. Maybe one weekend a month I'd like ot make a dozen passes down the track at my eventual goal of low 12 second quarter miles. I am wanting to support around 600-700 horses. Is the 68rfe available to retofit yet to older rams? Who has the best parts/service on a built up 48re? I have heard some good some bad on older posts about ATS, but Suncoast is only a hour drive from me. I just feel a bit silly with the idea of putting 6 grand or more into a prehistoric design 4 speed auto, no matter how tough it is. I think I read that mercededes has come out with an 8 speed auto for one of their big sedans... so thinking about wanting 5 or 6 speeds for a truck with an already narrow rpm band seems reasonable. I am hearing nightmare prices at times north of 8 grand for a built 48RE. What gives?

Don't forget Goerand Bros. (might be about 6 grand if ALL billet, sure not 8 grand!) Goerend Transmission Incorporated and

HTS htstransmissions.com/index.html

I like Goerand, I have their parts waiting to be installed-good prices, won't find anybody saying anything but good about them, maybe little hard to get hold of (until you get on their call back list-just 6 people work there), call early in morning their time.

Love my Goerend trans. Best bang for the buck I found, and excellent service.
