    Instead of rebuilding my stock 700 I've decided just to buy a new (rebuilt) one. I'm not looking to get a fully built unit, just a stock rebuild with some HD components. So I'm looking to spend around $1k. Here are my options:

    http://thetrannydoctor.com
    or the JET 700R4, TCI, B&M...

    If anyone has had experience with these trannys please let me know. I'm open to more suggestions.

    Thanks in advance.

    A guy in my 4x4 club has recently installed the Raptor and he is very pleased with it.

    Chaz, What went wrong with all those 700's. Where did you get them from?

    I'd love to get the Raptor but its a little pricey. Maybe I'll just save up for it.

    I love the Raptor... My cousin turned me on to them. From what I hear definetly worth the money. Otherwise I think you would be very happy w/ the TCI. I have used a few TCI trannies (althought none a 700) But they are great!

    I think the Raptor might be overkill for my stock 350, although I wouldn't mind the extra beef. Anyone ever deal with TheTrannyDoctor.com?

    Nothing about a 700R4 is overkill. They're really not all that strong. I love their gearing and their overdrive, but they will never were the most dependable or strongest trannies.

    you seem to be very knowledgable &amp; well rounded. you really gotta start taking in a wider arrange of information / opinions, and realize that you do not know everything. there are a lot of people out there who have a lot more experience with this stuff then you do.


    quote from the guy that makes the raptors, and he's willing to back them up with a guarentee of handling up to 600HP!!! he sells these things to replace th350's, and th400's as a tranny with an OD option!

    <blockquote><font class="small">In reply to:</font><hr>

    I have one in my one ton Suburban with 463 cubic inches and 455 foot pounds of torque. I pull a 5,500 pound trailer in overdrive all the time. The 700R4 has a 3.06 ratio in first gear, which is 20% lower than most transmissions. The 30% overdrive will give a 30 to 40% increase in gas mileage on the road. This transmission is for any type high performance / heavy duty use up to 600 horse power.

    <hr></blockquote>

    you seem to have a hard line opinion, and whether you are right or wrong 'that's your story, and your sticken to it'. man loosen up, and don't be quite so controntational.

    remember, we are all friends here...

    I gotta tell ya there are companies out there who can make a good 700r4... no matter how adamant you are in your 'opinion'

    I've had the raptor for over a year right now and I am greatly satisfied. Guy in our club here had one behind his 6.2 and installed a filter on it. The filter or something with the filter got loose and a rubber piece got into the valve body and messed up the entire transmission. The Transmission center (people who build the raptor) rebuilt it for free even though it wasn't their fault. How's that for customer satisfaction. He's on this board, think his name is Agdiesler or something like that. David if your out there speak up. Later - Doug

    Where have you been! People here have been asking about the Raptor for a while and no response. So do you think its really worth the cash?

    I've praised the Raptor ever since i found it and installed it. I've been here for a while now and even asked questions about it over a year ago if anyone had it. I put up the links and all, and i think thats what got the raptor going here. No one seemed to have it before me, or they didn't say anything. At the time my cost was 1240 and compared to a shop around here that thought the corvette servo was the strongest and charged 1160 i think it's a steal. Later - Doug

    What stall convertor did you go with? Do you use yours as a daily driver?

    '85 k5, 350, 700r4, np208, 10 bolts, as of 10/2001; wish list is extensive.

    My vote is for the TCI. $1200 dollars. $75 shipping.

    I bought a Raptor700 in anticipation of installing a turbo along while my rebuilt diesel, but Gale Banks Engineering is very proud of their product, and the turbo was put on hold. Being a chronically poor college student doesn't go well with the four wheeling bug.

    The transmission did fine around town, and with a little bit of tinkering on the governor, I was able to "dial in" my shift points. I had recently installed a tachometer, ATF temp gauge, auxiliary spin on filter, and a B&amp;M 24,000 GVW cooler. I was happy, but with my eye on the gauges, I watched the whole thing go to hell.

    A few weeks ago, while en-route to Dallas, my 6.2L diesel powered suburban was cruising 70mph @ 2000 Rpm, the torque converter started locking and unlocking sporatically. Then, I lost fourth gear and the Rpms went straight to 2800. About two second later, my transmission temperature gauge that had been sitting on 160F-170F pegs at 350F. A cloud of burnt fluid covers the cars following me. My 600hp performance transmission just took a grumpy. At around 11:30PM, I pull over.

    The smell of burnt ATF has to be one of the top five worst smells on the planet, so working in it was a real privilege. The stuff was dripping everywhere as the nasty brown fluid had come out the vent tube at the top of the tranny and sprayed all over the underside. While crawling around under there with my Mag-Lite trying to diagnose the problem, I had hot fluid drip on me more than once. It left me with a few freckles. I called my father in Dallas, and he flat towed me about 40 miles home with his 6.5TD suburban (it's a family thing).

    The next morning, I pull the pan only to find chunks of metal the size of small marbles lining the inside. As it turns out, the little rubber O-ring that holds the in sump filter/ATF pickup failed. This caused a lack of fluid circulation and overheated the ATF.

    I called the Raptor folks in Bossier, and Richard said that he'd take care of me. That, in my opinion, is the single best reason to purchase a Raptor700. The people on the is board know all to well the lack of quality customer service with which me are met, and what truly sets apart the folks at the transmission center is their service. Beyond that, the personnel that work there are unlike those at the AutoZone parts counter. They are very knowledgeable, and more than willing to help.

    For the interim, I've reinstalled my old TH700R4. The funny thing was that the temp gauge gave me no warning as to the impending failure. It just went from normal to WHOA! Well, the tranny had gotten so hot, that the signal wire which I had routed to go across the bell housing from the temperature sending unit had melted and thus grounded out. This caused the sharp spike. I've since re-routed the signal wire to go up to the firewall and cross over with the engine loom.

    On the upside, due to the fluid spraying, I have what looks like a freshly painted undercarriage.

    How long has it been behind the 6.2. They aren't the new Duramax's but they still put out plenty of torque compared to some motors. The tranny itself didn't necessary fail (meaning it wasn't a hard component failure), could of happened to any tranny even a 4L80. I have not boughten a Raptor, but from what I hear (and from what you say of the customer service) I would recommend them to anyone looking for a heavier duty replacement.

    The new diesel has only 2500 miles on it. Even though it's still at the naturally aspirated level, with the performance upgrades I've made, I'm pushing 300 lbs. ft. The Raptor saw about 2000 of those miles.
