    I toasted another 700R4 today. This is my 4th dead 700R4. I was on my way to go wheeling and out of nowhere OD went out. I was cruising at 2300 RPM in OD and bam OD goes away. Then about 3 miles down the road 3rd starts to slip. I get off the highway and I don't have much of any forward gears. I had enough to get off the road into a dirt lot and that was about it. Reverse is gone to and makes some bad noises when I try and move it.

    I was even doing everything I know of to keep this one alive. I have a trans temp gauge which was reading normal to cool, external stacked plate trans cooler, and also I had just added an external trans filter kit about 3 days ago. So now the truck sits until I get the money for my next transmission.

    Are you running a high enough ratio in your axles? I think someone had a problem with this too. The ratio was too low and caused the tranny to slip all the time. I don't know, maybe you're just running a 1100hp(before the nitrous) big block? /forums/images/graemlins/confused.gif lol that would be sweet. /forums/images/graemlins/eek.gif

    <font color="green"> Zakk's the one that was toasting trannys from having too high of gears. The tranny was getting really hot, he changed the gears and it went back to normal temps, IIRC. </font>

    Gears are fine. I am running 4.56's with 35's (really 34"). I am spinning about 1800-200 RPM so the converter should be locked up, and my RPM on the tach matches what the calculator says it should be. So no slippage, but something gave up its guts on the inside.

    I am not even running a high power motor either. I am running what is supposed to be a 300HP 350CID crate motor (I have doubts as I think the GM dealer screwed me over) MSD igntion, K&amp;N, and dual exhaust. No headers, no fuel injection, no nothing special. I wish I did have a big ass motor so at least I would know why I was breaking trannys ever 10-15K.

    The factory 700R4 lasted 100K, and the 3 after that have only lasted a combined total of 55K. The last 3 have had a 350 instead of the 305 the first one had, but the first one only had the factory trans cooler and was towed with a fair amount. The last 2 have had an external cooler the whole time have seen very little towing.

    Is there something common between all these trannies? Like the same shop building them? There's got to be a cause somewhere.

    I gotta say, barring the normal issues with auto trannies (high stall, high gears, no cooler) I hear about 700r4's going out all the time on full size trucks with no rhyme or reason. I've seen th-350's stripping the main drum on the input shaft on 2nd to 3rd gear shifts under load when not beefed out and dont really hear about th400's going out at all. With everything I've put into my th-350 and how reliable it is now, as much as I'd like the 4th gear theres no way I'm going to step over to the 700-r4 and having the lower first gear keeps me from moving to the th400. It's really too bad the 700-r4 is so unreliable, I'd like to see someone turn it around and start producing a reliable and cost effective 4 speed on a full size and make it a realistic choice for the 4x4 enthusiast and not just a light street car tranny.

    If you want to stick with a 700r4 maybe you should check out these guys. www.bowtieoverdrives.com
    Personally, I haven't ran a tranny from them, but I have talked with the owner via e-mail about some issues a few times. Aside from being a 700r4 guru he is a very helpful person. Take a look at the info available on his website he knows this tranny like the back of his hand. /forums/images/graemlins/thumb.gif

    This post (and others) make me question why I am working toward a 700R swap.. Then again I have heard of others who dont have as many problems. All the tech I read about the 700R says the TV cable must be properly setup. Not saying that is your problem but this is worth a read http://www.tvmadeez.com/index.html

    Harley, make sure next time that the TV cable is absolutely perfectly adjusted properly. Worth paying someone a few bucks to adjust it right. Something is causing your problems, sounds like you've done EVERYTHING you can to keep it alive and it STILL dies.......... /forums/images/graemlins/laugh.gif

    Hey dude, that sucks...


    Did it do alright on the trip down to AZ? I will keep an eye out for any screaming deal on a 700, cuz there is now way I will ever be needing one /forums/images/graemlins/rotfl.gif Anyhow, I think the TV cable was you problem...I know it was mine in the 700 that we swapped in my truck last spring...remember how it would hold the gears for a very long time...well after taking it to 3 different shops, it still was all jacked up so I messed with it a bit and it was okay...but as soon as I saw dark tranny fluid after like 3000 miles I said screw it and did the 465 thing...


    If you didn't have such tall gears and short tires, I'd say go with a 400, but I think for you, OD is necessary...


    Good luck buddy...

    I am pretty sure that the TV cable was set right. I bought this last tranny used from a professional mechanic. It was a GM Cert. trans, and when I bought it he still had the TV cable set from when it was in his truck. He said as long as I didn't move the cable around at all when I installed I wouldn't have to set it. I didn't move it so it should have been right. It actually shifted and ran the best out of all 4 trannys I have had in the truck.

    The 2nd and 3rd were built by the same shop that is susposed to be "turbohydromatic specialists". Apparently he doesn't know enough as the both only lasted about 15K each. Just long enough to get off his 1yr/12K mile warranty he offers with his trans. To be fair though, the failure of the 2nd trans was my fault, but the 3rd wasn't.

    Chris: this trans got me back from Colorado ok, but it was trying to go out on the last 100 miles of the trip. I thought it was my drivers side cat going out that was causing my lose of power, but apparently it was the tranny. After I got back and it cooled off it ran fine around town with no probs. Then when I went about 25 miles on the highway it went out. It didn't show any signs of going either, no bad shifts, slippage in gear, etc. It did run a little hotter which I just attributed to the extra heat in Phoenix as compared to Colorado.

    I am looking at the Bowtie Performance trannys but they are alot of money for someone only making $8.00/hr. But I do have a vehicle to drive so I figure I will give it a shot and save the money for one.

    Thanks all.

    I actually bought it from DesertDueler (Dan) here on the boards. He regeared and locked my axles for me too. He is a certified mechanic and his father is too. I was told that I wouldn't have to reset the cable by both of them if I didn't mess with it. He is a good guy and has always done me right so I don't think that was the problem. Even if it was it should have shown up in the trans temp gauge which I monitor frequently and it never was out of line.

    When I installed that tranny it actually was the best shifting transmission I have had in the truck to date. It was the best all around on shifts. My 3rd tranny shifted 1-2 faster and harder, but the last one shifted up fine and downshifted alot better then the 3 previous transmissions did.

    Not to ask any dumb questions, but did you flush the cooler lines for the tranny? If you keep blowing something up like the the way you have without getting on it hard, then the problem is something else. If you blow up anything that rely on hydraulics, you suppose to clean the entire system and put new fluid in. Contaminated fuild can do lots of damage if not taken care of.

    Sorry to hear another went out on you. How many miles did it last?What kind of RPMs were you cruising at back down to AZ? Did you cruise home on the 32s with 4.56 gears? You could have actually been overgeared and was spinning the tranny to high of rpms which will wear a tranny out alot faster. I would say go with another GM certa that way you get the 3yr/50,000 mile warranty nationwide. I believe they are 1400 bucks.
