What adustments can be made to a TH700R4?

I know there's a TV cable, but are there bands? I have a 87 TH700R4 that's getting a bit sloppy, and I want to make sure it's in proper adjustment.

Thanks

CJ

are the shifts on time ?

is it full of fluid ?

if 'yes' to both, that's about it

No the bands are all hydraulic no adjustments possible. If it is slipping and the filter is in good condition then it is rebuild time. The TV cable only changes the shift points. If it seems like it is not solidly in gear maybe the torque converter is no longer locking up. This will give a "slip" feel in 4th cruise, when cruising, foot on the gas, lightly put your (other) food on the brakes, you should feel it unlock and the revs jump 4 or 500 rpms. If not then it isn't locking up.

good luck, mark

I have an 85 Vette with same trans. If you take off fast it shift normal. I f i ease off,it shifts 1 2 3 over drive really quick. How can i change this??? By 25 mph its in over drive. Thanks Gil

adjust it for slightly more pull-out of the throttle cable

one or two 'clicks' of the adjuster at most, at a time

The fluid is new, I changed it in hopes of helping. The filter was replaced not too long ago, and the machine tested it to pass the fluid well.

I'm an idiot and let the fluid dip too low, allowing it to slip in a full throttle shift from 1 to 2 not long ago. That 1 to 2 shift was soft before, and is about the same now. I know the trans is not gonna last forever, but I'd like to make it last as long as I can since I can't afford to replace it right now.

As to the question on the timing of the shifts, it depends, actually. When it's cold, it seems to take longer to shift than I'd like, but otherwise the shifts are sluggish. I don't know if I'm describing this very well.

As to the torque converter, the lockup operation is intermittent. Sometimes i have noticed it, but most of the time, I don't feel it lock up or unlock. I've felt how the lighter fwd gm cars act on lock and unlock, and I don't feel that in this tranny.

Would this transmission be damaged by the operation the OP described, the very early light throttle shifts?

depends on the load on it

heavy load, a definite possibility

Yes I had it flushed. No, I don't consider that to be a mistake. I've heard all the arguments on both sides of the issue and made an informed decision. Fluid that has been broken down will not work properly. Removal and replacement with good fluid is the only real option. If the tranny subsequently takes a dump, then it's because the tranny was let go too long in the first place and there was damage to it.

ROTFLMFAO.....

I really liked the part where you said if it takes a dump after the flush job....then the unit was already trashed.

so.........if you already know it's trashed... why all the questions..????

Maybe you need to consult all those folks that told you to flush it.....maybe they will tell you what's wrong..

You know......get yerself some more of that info so you can make another INFORMED decision.

ROTFLMAO

I didn't say it was. I know it's a bit soft on its shift from 1 to 2. I've had this van for the last 30k miles of its life and it's been a bit soft since I got it. I also admitted that my neglect probably hasn't helped it any. However, it's still running ok and I'd like to prolong its life as much as I can.

My dad has a 1995 F-150 4x2 with the 4R70W transmission and a 4.9 I6. At about 95k miles, it started shifting very softly. We both suspected that it would die shortly. He had his fluid flushed. At 150k, he had it flushed again, for good measure ;-) Today, it has 220k with no failure.

Lastly, you haven't read the facts of this post right. The flush didn't affect the performance in a negative way. In fact, it helped it a bit. I just wanted to make sure that there wasn't something that I was overlooking.

Actually, let's just shoot straight, shall we? Some of the deductions you've made are true, some are not. "Pops" doesn't know much about automechanics, and doesn't do any recommending. I have several friends who own auto shops, including one with a tranny shop. I don't take the word of any 1 mechanic. I prove the advice I get by getting as much information and as many opinions on a subject as possible. I've found Gary Glazener's advice to be very sound in the past, and that's one reason why I stopped in here at alt.trucks.chevy. I've run in to him in a couple of newsgroups over the last year or two. You can search for me and my previous posts at google groups under the email addresses snipped-for-privacy@citynet.net and snipped-for-privacy@inetone.net

You'll find out if you dig around that this tranny had problems when I got it. Most notably, it shifted back and forth between 3 and OD. Gary stated at the time that it sounded to him like there were internal seals that were leaking and that it probably needed a rebuild. Since I figured I wasn't gonna do more damage than it already had, I added a snakeoil product that "conditions" seals. Believe it or not, it made the symptoms go away for the last 30k miles. I know full well that the tranny is a pig-in-a-poke, yet it's done remarkably well. With that in mind, I wanted to know if anyone, ie Gary and other tranny guys, had any further suggestions.

Also, the reason my response to you was that you didn't understand the situation is that you stated an earlier assumption that the tranny flush had caused an unwanted result, which is not the case. I stand by my informed opinion that a tranny flush will not in and of itself cause a transmission failure.

Lastly, your writing style, while cute, tends toward confusion -- one more reason I'm not sure what you're trying to say sometimes. It's probably just me. I do understand that you believe I made a mistake in flushing the transmission and that it will implode within 3 months. The interesting part of the whole thing is 1) I disagree with that assumption, and 2) you cannot possibly prove that a flush is the cause of a failure. It's simply impossible to prove your hypothesis without a ton of scientific data. For example, in the case of my transmission, if it fails, how could you prove that it wouldn't have with the old fluid? It's scientifically impossible to prove your position. If you're offering it as opinion, that's fine; if you're offering it as truth, that's another story.

I'll make you a deal. I will give you an update, mileage-wise and time-wise on the tranny. Right now, October 22, 2003, the van has 101,500 miles. I'm within 50 miles of exact, because I noticed today that I'm within 500 miles of an oil change, which is due at 102k. January 22, 2004, or as close to that date as I remember to, I'll give you a report. If you're right and it fails before then, I'll report it as soon as it happens. Fair enough? The funny part is, I'm surprised the thing has lasted this long. If your assertion that I've doomed the tranny by flushing it is true, I have two strikes against me because I'm working with a tranny with known long-term problems. I'm not hedging, I'm just saying that you're making a pretty safe bet.

Only question I have is, which alias do I address this to? :-)

Chris, there actually is something you could do cheap if it slips going into second that might get that "last dollar" out of the tranny. Sounds like it isnt actually slipping(?), so all you really need to do now is drive it very easy and hope for the best. GL

You're correct. It's not slipping except for that one time due to low (and nasty) fluid. The entire point of this post was to find out if there was an adjustment I needed to make to save what friction material I have left.

lets shoot straight...... yer running around in a tranny that's gonna leave you sit'n one day because yer try'n to baby all the mileage out of it that you can get.

so.....add the tow bill to whatever your buddy at the trannyshop quoted you on the rebuild.

and.....YES...it is my opinion that the flush job is a bad thing. What does yer buddy at the tranny shop think?

and....if you ever have the chance to go to a tranny technical seminar with yer buddy .....go...and bring up the subject of transmission flushing and see what all the transmission guys reactions are... and then make yer INFORMED decision.

OR.....just call a couple tranny shops and ask them for their opinion.

Sometimes, scientific data isn't needed in order to confirm fact. If you had a town full of people catching cancer down the road from a chemical plant....and you lived in that town.....would you move?....or would you wait for the scientific data to arrive telling you all was not well?

How bout if you were hearing that a majority of the vehicals like yours.....were doing summer saults down the interstate because of faulty tires? Would you wait for higher minds to determine what the cause was... vehical height...improper preasure...tire design.......or would you just run on in and take them up on the offer of trading the tires out?

any whoo......

you need a rebuild

perhaps not on a 700

but I've seen a couple of A4LD's, the Ranger / Aerostar / Explorer unit, that were flushed and flat refused to move afterwards in 'OD' or 'R'; they would pull forward in 1-2-3

on teardown, the 'input sprag', the one-way clutch assembly inside the overdrive unit, was not holding under load, presumably because of debris (washed loose by the flush) preventing it from holding by filling up the microscopic grooves in the races that the sprag elements 'grab'

since the 700 uses a similar sprag (but a bit heftier and smaller diameter), I'm waiting for the first one of THOSE to arrive with the 'after-flush blues'
