700R4 question

dirtwarrior17 said:
Not sure what you mean by 4 row but that sounds like a stock radiator. The radiator tranny coolers will still be about 45 degrees hotter than a seperate cooler.

Usually when a stock 700 goes with the stock cooling system hooked up (radiator cooler) its because they got too hot.

IMO yours gears should be fine if there is no noise because in order for that to be a gear it would have to be completly stripped and if that were the case you would have metal all in your gears and wouldn't be able to go more than half a mile before it blew completly.
dirtwarrior17 said:
I got one for ya.... if there are no "gears" then why is there filters for metal shavings? where could metal shavings be coming from? hmmmm ...... gears.
dirtwarrior17 said:
that was a while ago now and almost all of the answers i give are either what i did to fix something i had to deal with or I will take an educated guess on a subject that I am just trying to help with and had some experience with, not say this is the answer on every post. Its gotten alot better in that aspect. Yeah you can go back and pick out posts from weeks ago but recently most of my answers will have questions in them if i don't know or I will say straight up i don't know crap about this but.... then give some sort of general knowledge just to get the thread moving... I am NOT trying to make you all think i know everything but i feel like I have to prove myself in some aspect because of the mini mull bs contest.

As for the 700r4 subject... read the whole post. I get misunderstood because of the bad posts in the first week. I am offering a solution because i have a 700 and have done a lot of research on how they work because I had problems with mine. What I wrote in this post(and others like this for example the starter one), is from real world experience and research. I know i have posted some real general crap and fought about it on old posts but somebody please show me a recent post where i got this "know it all attitude".

ever since this started, a few (won't name names) try extra hard to make me sound like a dumbass and im getting tired of it... statements like autos don't have "gears" is just one example.:grin:
dirtwarrior17 said:
I was giving him an answer to his post name.... dead 700r4? thats all He wanted to know if the whole tranny was gone and i basically said no because of what it was doing and tried to explain to him that it couldn't be the gears and then said it might be a servo... I also said i forgot about the reverse clutch pack. I am not sure but i beleive it has nine clutch packs.


When you say gears what do you mean? I think it has 4 planetarys and one sun but im not sure. I never said i knew any of that and i don't need to becuase i am not telling him for sure what is goin on you are. Moving gears whether planetary or not create very small metal shavings that along with others get picked up with the filter but some still make it to the fluid. Not chunks, shavings. Those words are right from 2 very knowledge trasmission shops one being the biggest we have up here.

I posted on this because i have a 700 and spent alot of time finding out how it works to correct my problem.... What posts are you talking about? the whole 396 crap was a bunch of bs where i said i was wrong and it all got way out of proportion...and i wasn't the only one invovled. Its the things like axles, brake boosters, etc that i don't really have a clue about but i know the 700. You would be suprised how many things i have had to fix on that truck in a coulple years.
convinced yet kid? i specifically remember reading one of your posts that said that you had taken it to a shop, and it cost you $900 to have the 700R4 rebuilt. that's fine, had you not bragged about how much "knowledge" you have about the 700R4, you know, with its 9 clutch packs, 4 planetaries, and one sun gear. damn, with all that stuff in there, where do you have room for all the gears. RJF asked you to keep your opinions to yourself when facts were requested, you really should think about actually doing it, rather than saying you arent, but continuing in your "old ways"
 
dirtwarrior17 said:
alll im gonna say is read my first couple posts and read what rjf said....
You also have to remember right now, your still in training, he has decorated stars.And im still learning myself.
 
no... where do i give him anything that is not true and where did i say i knew how many planetaries it had... wasn't telling anybody that. he was testing me.

I said the guy i bought it from who lived in sac had it rebuilt. couldn't count how many tranny experts i have delt with because of the problems i have had with mine. My brother did a swap with one of these 2 years before i had a truck.

Usually when a stock 700 goes with the stock cooling system hooked up (radiator cooler) its because they got too hot.
call any tranny shop. ask them what the most common reason a 700 goes.

IMO yours gears should be fine if there is no noise because in order for that to be a gear it would have to be completly stripped and if that were the case you would have metal all in your gears and wouldn't be able to go more than half a mile before it blew completly.


how is this false? you or somebody said themselves it was the clutchpack not the gears


I got one for ya.... if there are no "gears" then why is there filters for metal shavings? where could metal shavings be coming from? hmmmm ...... gears.


84 said that autos don't have gears. and ask any tranny expert or shops shaving come from gears planetary or not.

None of these prove anything.... I am real tired of this.

Any other suggestions for the 700R4 on 35's ?
I have been running 35" boggers, 4.10's, and built th700 for a couple of years now, no problems to date, not even an overheat. I do however think that anything taller than 4.10's (3.73's and numerically lower) would be causing too much heat with a Th700, on 35's of course.
 
you took a guess at how many it had, which was followed by a response from TJ telling you how many planetaries it actually has.

95% of all trans failures are due to too much heat, and the stock cooling system is adequate under NORMAL loads.

exactly my point on the gears. the gears do not strip as you suggested. they do not strip because they do not exist. the clutch pack frictions and steels wear to the point that they can no longer be engaged, they just slip.

you have been corrected on the shavings in the oil as well, it comes from the clutch packs that you apparently did not know about. planetary gears do not wear enough to produce a significant amount of shavings to even be noticed in the oil. something about being hardened gears that keeps them from wearing. :screwy:

stop what you're doing then.

some people's kids... :rolleyes:

My point exactly... that had nothing to do with anything on the post and i never said i new that.


wheeling a truck in low all the time with 35's is not Normal loads

I said that they couldn't be stripped because of what it was doing....

didn't know about clutchpacks? this is rediculous.

I guess the techs at nor cal trasmission are wrong.:grin:

dude did i say i was.... you think i did somewhere.... please show me. everything i said came from the techs at nor cal so everytime you just said im wrong your basically arguing with the guys that rebuild em. I'm just passing along what they told me.

Alright......it's takes a LOT to get me pissed off, but you guys are really testing my patience!!!!! :mad:


Dirtwarrior17, beater_k20, sweetk30:

Knock it off! If there was some bad blood from an earlier post, either get over it or kiss and make up. Otherwise prepare to be removed from this site. If all you can contribute to a post is hurling insults at each other, then you are wasting space here and certainly aren't helping the original poster learn anything useful, except maybe how much CK5 is starting to look like Pirate. :angry1:


rjfguitar:

" Let someone that knows information about the subject answer his question."

is the inflammatory statement that started the blowup on this thread. As a fellow moderator, I hold you to a higher standard and expect you to choose your words more carefully around here. You more than any of the others listed here are responsible for the cooperative spirit of CK5. I know you pretty well, and I know you are capable of much better than that.


flatline: (the original poster for those who forgot!)

Sorry the thread went to hell on you....despite our best intentions it does sometimes happen. You will see that this type of behavior is the exception rather than the rule around here, and I hope you stick around long enough to see that for yourself. :thumb:

For what it's worth, I had a 700R4 in an '88K5 with 35's and 3.73 gears. I never dared use the overdrive for fear of overheating it, and I don't think the engine could have held it in OD anyway...not enough revs. A transmission temp gauge is probably another great addition to your plan. A sender can be added to the tranny pan without much effort and you'll be able to monitor temps and really KNOW whether things are getting too hot or not.

yikes, glad order has been restored... good job mods! :) anyway, one thing to consider if you don't want to add a sender to your pan is they make trick in-line junctions now that you basically plumb between your tranny and the cooler. Looks like a billet aluminum "T" sorta, pretty bling. I saw them in a recent fourwheeler/petersens but I forget who makes them. In any case, this is a great mod for anyone who is already replumbing their tranny cooling lines anyway and negates the need for messing with the pan (which, who knows, you may need to swap out at a later date for some reason, losing the sender mount). When I replumb my tranny lines (next paycheck!) I'm gonna use one of these...maybe I'll do a write-up or something for the tech forum.

welcome to CK5 Flatline... :D

i'm no 700r4 expert but just to reitterate Jeks and Gregs point... i run 32's, 700r4 and 3.73's and barely get into OD except out jamming on the highway, could use 4:10's right now..... as others have stated between bickering, 4:10 is about the minimum your gonna want with a 35... imo i think 4.56's are much more where you wanna be..

i'm about to intentionally run your setup soon.. gonna run 36's with the 3.73's for a little while till i can regear.. i expect to never see OD.. i have a little insurance with a nice cooler, gauge and a remote filter (which i consider mandatory for the 700r4. remote filters are pretty cheap and usually have a port for a temp sender which can make life much easier). as soon as i can regear i'll step right up to at least 4:56, if not 4:88's, depending on what running gear i find.....

i would try to make a regear a top priority, as i will, when i step up the tire size.. i would assume the truck is a little doggy now anyway and the pep from the gear will make the truck much more enjoyable...

unfortunately your friends fears are sound, but at least your aware now and can take proper precautions.. hope some of that helps and apologies for your thread taking an ugly turn... :blush:
 
700R4 and how to keep it from overheating - kind of ...

I own a 1991 GMC Burb. 350 V8 700R4 4x4 1/2 ton.

I live in Denver, Colorado. My parents live 850 miles south of us in San Angelo, Texas. On the return trip of visiting them, my overdrive impellor failed, causing a loss of my OD. When I stopped for gas there were no leaks, so I just drove home in drive. My average speed was 75 mph as it is almost all freeway, except between Amarillo and Raton.

When I got home, I had the tranny fluid changed. WHY? Because it had gotten SO HOT that it literally boiled the water out of the fluid. I HAD RUST on my tranny dip stick. The fluid came out BLACK and very VERY thick.

THE REASON I was not left on the side of the road is because I use a product called PROLONG in all my vehicles. They make an engine additive, a tranny additive and a fuel system additive (plus others, but I digress).

When I took my truck over to the tranny rebuild guys my drag racing mechanic uses to rebuild his transmissions in his dragster (handles his 7000 hp engine), I asked what happened.

"Overheated," was the response. The next question was how bad did it sound driving it over there? My response was that it didn't make any more noise than regular. Again, after disassembling the tranny they found an exploded overdrive impellor. They showed me the main pieces.

As I am planning an upgrade to my engine, I had them rebuild my tranny to handle 700 hp (upgraded bands and a couple of stiffer springs if my memory is correct). I also had them add an additional cooler. My truck already has the inside the radiator tranny cooler. Apparently when installing the cooler, they nicked one of the internal lines. After picking the truck up one evening, the next morning I was pulling a motorcycle trailer to go pick up my bike in Boise, where my BIL was keeping it for me. I got about ten miles down the road when the 'nick' in the cooler blew tranny fluid all over the inside of my engine bay. I limped to an Auto Zone and bought a new tranny cooler for about $45 and installed it myself. It was a tick larger than the one my tranny shop installed . Problem solved. When I returned to my tranny shop after my trip, they refunded my costs involved and apologized profusely for the problem. Boise is 850 miles north and west of Denver. I pulled an empty trailer there and the same trailer with my 800+ lb Harley (FLHTCU) on the way back. NO PROBLEMS.

As a side note, apparently tranny fluid is a GREAT engine bay cleaner, because when I washed the engine bay to remove the tranny fluid after fixing the problem, BEFORE driving to Boise, my engine bay was clean enough to eat on. GO FIGURE.

It's been about six thousand miles and two years since this problem occured. NO problems since then. I am about ready to change the fluid to Royal Purple tranny fluid, as it does lower the operating temperatures in EVERYTHING I've used it in to date, which is my Harley (engine and tranny), my wifes 1996 Subaru (engine, tranny, both diffs and radiator [Purple Ice]) and my Subs engine. OF COURSE all the vehicles we own ALSO get a dose of PROLONG every ten thousand miles. Probably overkill, but hey, I haven't WALKED home due to any overheating issues.

If you have any questions, don't hesitate to contact me.
 
i have a 700r4 35s and 3.42s. i have to run in drive to keep it useable, in OD it runs just way too low. with the stock motor i was not worried that the tranny would not last, but now that i swapped in a higher horse motor, im kinda woried that it might break something. once i regear, ill feel better.

i built this tranny to work in my truck with the stock motor. now with this new motor thats probably twice as powerful, i feel there is too much strain on the tranny. once i regear, the strain will be lifted and i don't think i will have a problem with the tranny.
