Is my 700R4 dead?

it could be as simple as a stuck valve.

This is so true, I had the same problem with a 89 trans am, I know a trans
guy that told me to lift the rear of the car and put it in reverse and spray
a whole can of WD-40 in the filler tube, as stupid as it sounded, I did it anyway
as I had nothing to lose, after about 25 minutes it worked again. (4-REALS).
but i put it in drive and reverse from time to time.
 
you mean you where spraying WD 40 into the transmission itself? I might try this, since it is the same transmission.
 
If you don't get any gear at all, its likely because the seals or the clutches are shot.

If anything, the silicon in the WD-40 swelled/softened any leaking seals up enough for them to actually work again.

This is why I am a fan of the "trans fix in a can" that has come out fairly recently.
 
Originally posted by beater k20 but it is not the cause of the metal shavings you see in the fluid

The filter is for anything that drops down into the pan but the gears "can" produce shavings.

YES, start with like half a can through the filler tube :)
my trans has worked great since i did this. i did change
the fluid after like a couple hundred miles.

read the rest of the post kid. they do not produce enough to make a noticable difference in fluid color. if they do produce enough shavings to bee seen in the oil, you'll hear them, you damn sure wont be able to miss it.
 
yup the post says that...

the local tranny shop tells me that shavings from the clutch pack and gears will still make it into the fluid.
 
believe what you want kid. local trans shop also told a friend of mine that her Grand Am needed a timing chain, its sitting in my garage right now with no injector pulse, timing chain is absolutely fine. they'll tell you all kinds of crazy stuff.

Ya know I hate to but in but Ive been reading dirtwarriors posts the past few days and Ive about had enough of his "know it all" attitude.

Boy you need to grow up and realize you dont know everything and stop acting like you do because its getting very annoying...
 
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.

Beater deleted all his posts maybe i should do the same to avoid this...
 
man what exactly are you talking about? exactly? Because if it was the 396 post then it looks like that because beater erased the posts that pissed all of us off.

he's got you snowed...:grin:

I think you should read more of my recent posts before you say something like that. I have been saying it could be.... along with my guesses on almost all of em... look at tractions aids, starter problems, and 4" lift.

I mean i want some sort of evidence im tired of people saying this sort of thing after they don't read the entire conversation.

I have noticed that from his first post. He thinks he knows how most everything works, which in some aspect he does understand a handfull of things but in a broad range, no details.

I spent a complete day following him through about 10 different threads quoating and correcting his posts because he was giving answers to questions that he thought was the problem, which half the time wasn't at all, and the other half sort of right but still wrong. I am tired of cleaning up after him.

He needs to sit back and only post answers to questions he knows, and spend twice as long trying to learn than teach.

Dirtwarrior,

First off I tried to send a PM to you a few days ago on this subject but you have it set not to recieve PM's. You need to relize that you are still a student in the automotive world here at CK5. You have no problem admitting that yourself but your actions show differently.

There is not very many, if any, places that have as much information on Chevy trucks, and any truck really, as we do here at ColoradoK5.com. We have a database basically of hundreds of thousands of old posts that contain answers to 99% of the questions in all the forums. I am a firm beleiver that all of the regular questions about the 69-91 blazers has already been asked, answered, and most importantly answered with precise facts and knowledge taken from experience. It's all there, just do a search. As a long time CK5 member and part of the staff... I take pride in that database that has the power to solve almost any headache in a matter of minutes just by the press of the search key.

Most of the long time members have taken it apon themselves, because they care about CK5 and it's rep. for great tech and precise information, to keep the continuing flow of that information in the ever expanding database CORRECT IN EVERY FORM! For instanse, we want someone that just can't seem to figure out what that vibration at 45mph to be able to do a search and find page after page of what the problem is and solutions for it, CORRECT solutions.

When someone comes along and starts posting tons of asnwers to tons of questions without having experience or correct knowledge about those questions, it could cause someone looking for a solution to the same problem two years from now a big headache because someone gave an incorrect solution.

You need to relize that you are here at CK5 to learn, not to teach. There are over 15,000 members last time I checked, don't worry, there will be at least one person that will know a solution, to every question asked. None of us know everything, I steer clear of the threads that I don't know much about, even if I have a rough idea, i will still sit back, let someone that does know the answer post, and learn something new or reassure my answer I had in my head.

Just sit back, chill out, and learn stuff 'till your head hurts.;)
 
I have noticed that from his first post. He thinks he knows how most everything works, which in some aspect he does understand a handfull of things but in a broad range, no details.

first off look at my recent posts. Seems like you are bringing up stuff from a couple weeks ago.....

I realized my first approach to this forum was the wrong one and changed it. You can and have seen it in the recent posts. because of that first week some people assume everything i say is bs and argue(when in fact its the other way around).... like this post. Not saying they all are but a few.

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:

first off, i dought you know enough about a 700r4 to DIAGNOSE a 700r4. if you know a 700r4, how many "gears" does it have? how many clutch packs? what clutch packs are doing what and when? what are common problem areas? what are not so common problem areas?

i have been inside a lot of 700r4s and i still don't fully understand how EVERYTHING works, but i know how to put one together and make it last under harsh conditions. i know a 700r4 better than any other tranny because i have been in so many.

the gears don't supply any metal shavings unless there is something else wearing them out. ALL the shavings come from the clutch packs, bearings if bad, pump, bushings, and other hard parts. other hard parts will break/wear out WAY sooner than the gears. if there are chunks, the tranny is junk, and i dought they come from the planetary gears unless you have some serious power. but you shouldb't be running that much power threw a 700r4 anyway. you can get 5 pinion planetarys aposed to the 4 pinon, but cost major $$$, im talking $200-300 each.

in addition to TJ's diagnosis, if reverse is gone, the others are nor far behind. low gear and reverse are actually "the strongest" points in the trans, as they run through a pressure booster to boost line pressure and hold the clutch packs and/or bands tighter.
not entirely true, yes other gears are soon to follow, yes it is the strongest points, but not because of any pressure booster. the "low" in the low/reverse pack is only enguaged when the shifter is in 1 (manually shifted) and reverse, there are 5 different points holding it in manual 1, as opossed to 4 on every other gear when selected manually. when the selector is in OD, there is only 3 points holding every gear, thats why D is stronger than OD (other than the fact that 3-4 clutchpack is the smallest and it has leverage against it)
 
the wd-40 MAY have un stuck a stuck valve, but i dought it. most likely it was the silicon that swelled up the seal on the piston as stated before.
 
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.
 
cant find my 700R4 literature from college, but i recall a boost valve in the 700R4 which boosted line pressure in the in low and reverse, very well may have been an integrated part of the valve body too. i'm going to look for it some more tomorrow. might even help solve the problem with some of my troubleshooting manuals. i've had 3 700R4s lose a direct clutch, havent heard of anyone else having problems like he's having in a while, everybody else seems to lose 3rd gear, without 3rd, its pretty hard to get to 4th.
