    This could be a long one so you might get a cold one before reading on . . .

    So basic rig rundown is a 88k5 with 350/700r4/208 and CUCV running gear. I am aiming toward and doubler and as to this point I have been gathering parts for an SM465 tranny swap also. I even have a SM465/203 setup complete. But in the last couple of days I have been thinking about staying with my 700R4. The big reason is of course compromise. I would love to keep the sm465, but in truth my and I will be driving this vehicle on the trail. I am afraid the SM465 might scare her on the trail. Also the overdrive on the 700R4 makes it much more practical. Also the pedal swap is concerning me, however that is easily fixed. So here are my questions

    1. Have very many people ran a 700R4 with a doubler with much success? I Stephen did in his TTC, but has anyone else?

    2. Besides cooling and fresh fluids what are some good upgrades to a 700R4 for this application

    3. I prefer to do all my own mechanical work and I don't think I am too bad at it, don't let me near anything cosmetic, but can the 700R4 be built be an enthusiast, read as having never rebuilt an automatic tranny, or does it have to built be a specialist? To go with this question is their a good shop manual that has the necessary steps and specs?

    Any information would be much appreciated. I would love to rebuild my own transmission just because A it is cheaper B if it breaks I know whose a$$ to kick.

    i have the follow-along-and-rebuild-a-TH700R4 video on DVD if you're interested. :) I haven't done the rebuild personally, but when my Raptor bites it I'm going to "go for it". It ain't my daily driver... if I screw up and it sits for 6 months I don't really care. ;)

    Have a 700/doubler in my rig for at least 6 years now. No problems. I did the short shaft when I rebuilt my 700r4. Got it from ORD. Was alot of work but worth it for sure. JUST DO IT!!!!

    700R4 Rebuild

    Did you do the rebuild yourself or did you hire it out? I am interested in doing, I just need to find a good book that describes theory and stuff. One thing I have seen is rebuild kits with extra clutches. In all the manual transmissions I have rebuilt you couldn't put extra stuff in, so I have been trying to find that answer. If you have any direction let me know. Thanks for the info on your doubler.

    I have a buddy that has a trans shop and he built it. There are many upgrades and updates for a 700. Depends on your pockets. You will need the short shaft from ORD. There are a few minor mods to get everything togehter but ORD should have everything you need, Just ask and they will take care of you. As for tech-support it doesn't get any better than ORD. Good luck and if you need anything just ask.
