    There has been discussions re, extra steels and frictions in the clutches of the 700; is this trick going around by word-of-mouth, or is there some new lit., or maybe I missed the latest Vette configuration?:confused:

    now days a 700r4 can be built purdy beefy several diff places make alot of good stuff but there are servos that a way better than the vette servos . bowtieoverdrives and www.700raptor.com both of these make good stuff, i bought a kit from raptor after going through 3 trannys , a friend helped on the rebuild, but i stayed with the vette servos untill about a month ago i orderd a new servo kit from 700raptor .

    Ask a good local shop that you know of. They can usually get their hands on different aftermarket performance parts that are just generic copy cats of top notch stuff for 2/3 the cost. It's been so long since I had my 700 all beefed up that I can't even hardly remember all that got done.( thats a good thing right? meaning I haven't had to think about it from the lack of problems:wink1: ). I have an aftermarket converter with a billet center hub and the fins are supposed to be better tuned. Extra clutches in the packs, bigger planetaries IIRC, modified valve body for more flow, and corvette servos.

    It was worked out well for me behind my 300HP/425ftlbs 406sbc.

    I just had my 47RE in my Ram Cummins diesel done and many of the same principles carry over, a better converter and more flow from the valve body. The 700 seems to have weaker internals where the 47RE needs more attention at the converter because of the diesel's torque.

    Anyway, I went through the same shop that did my 700 a few years back for my Dodge 47RE and went with a good aftermarket company that the shop had access to instead of the big trans names that advertise and saved a bunch of money. I'd reccommend you do the same.

    the extra steels and frictions have been put in 700r4s for quite a few years. even with a stock rebuild, they are usually put in, depending on what pack it is. the newest thing ive seen is a 1 sided steel/friction, it alows you to put even more in there for unheardof holding capisity for a 700r4. i priced them out once, its mucho expensive, almost not worth trying it unless you NEED it.

    I took the specs from Bowtie Overdrive to a good local shop and we built one for my rig. We left some of the items they use off since the B.O. trannies shift pretty harsh since they tend to build them for street rods.

    Remains to be seen. I've only driven it a few times and then parked it to put in a doubler and some other mods. It should be back up and ready for the trail by summer. The few times I took it out on the road it was good.
