man o man killed my 3rd today i'm pissed, i'm thinknnig about chucking the 6 banger and getting a buil;t tranny and put in an 8, second tranny that died the same way, i lost 3rd and 4th gear, just empty revs in those. the other broke the seal and burnt up

If you have the money DO IT. I definety would.

FAST RS

I had my tranny rebuilt and 3 times the same damn thing happed i would be driving and when it would go to shift into 3rd gear the engine would rev up but the tranny would not shift. Like it was in nuteral or something. The shop rebuilt it 3 times they tried to say it was cuz i was raceing it and began to ask how many tickets i have gotten. Any ways i feel no one can rebuild our trannys at all my friend had his tranny rebuilt in his 92 z28 and he went to make a 3 point turn and when he put the car in reverse the tranny just revved up and he ended up gettng T-Boned because of it.

I have never liked the 700r4. The early modle pump problems were insane. And most of them that end up in the junk yard should stay there.

Id try a newer one off a 90+ V6. Even a built 700r4 could take a crap on you, espically with V8 power.

Course you know a T5 would solve them tranny problem.

Its an easy swap if you just have them cut the whole drivers floor pan out of the doner car.

Man, I beat the **** out of my stock 91 700-R4 and could not get it to blow up. Same with my stock Ford AOD (possibly WORSE than the 700-R4...same overheating issues, but sloppier shifting)...the bastard has 147,000 miles, has been beaten like you would not believe, has the TV pressure cranked abnormally high and 1 3/4 bottle of Lucas Slip Fix in it and it retains all gears and has only slipped out once, going from first to second on a hot day.

What are you guys doing to these things to kill them??

Doward here:

Pre 87 700r4s are notoriously uh... suck.

Get the latest year 700r4 you can for the V6 (like... 4th gen 3.4 auto 700r4) or go with the T5 stick shift

AGood2.8

Two simple words- "Darrell Young"- your problems are solved.

I burnt up two 700-R4's in the matter of a months time... I was driving and then all of a sudden BOOM its made this horrible sound and then I only had 1st and 2nd and my passing gears on the 1st one I eventually lost all gears but the 2nd one I only had those listed... I had to drive it about 15miles to get it home so I just punched it so it went into passing then through it into neutral. I had the worst leak problem w/ the one I have now got that fixed and it runs pretty decently (got it out of a S-10 though I don;t know if that would make a diff. they are all TH-700-R4's) I am just waiting for this one to go since I put a 3.4 in the car. If it goes I just gonna go T-5.

FAST RS

My car is a 91 RS 3.1 and i have the same problem he described. When my tranny first went it blew the rear seal out. and it was destroyed. one of the many times.

Gumby

Course a T5 can have problems too. At 200,400 miles my T5 went. It had made noise in 3rd for a while but one day coming off the eway, after a good run. it got stuck in 5th. It took about 10 mins of floating the clutch to get rollin in 5th and did a no stop for anything trip home.

Then after the new tranny my slave cylinder for the clutch went out and it got stuck in 4th. That was a much easier trip home but it was the fault of the auto parts store.

The throw out bearing in the kit was bad, and it made the slave hyper extend. They made it right though, gave me a whole new clutch kit and gave me a federal mogual throw out bearing off the shelf and threw the one in the kit, away.

For those who have replaced their trashed trannies, did you replace it w/a stock unit, have it rebuilt to atleast 92 specs, have a "high performance" rebuild?

FAST RS

The place i went to i wanted them to put a shiftkit in and all that they refused to put one in i offerd to pay for the kit and more $$$ but each time they said no. Now i have a feeling my torque converter is haveing lock up problems but im not concerned about it. When do our converters kick in aroudn 1400-1500 RPM??? becasue anywere in that rpm range my car bucks like crazy.

Project: 85 2.8 bird

Mine has a shifting/hunting problem around 45mph, went it wants to do the 3/4 shift. But then I also have a slight driveability/emissions problem also.

Heat = #1 killer of 700r4's

Waiting more then 1 year to change trans fluid = #2 killer of 700r4's - why? See the #1 above ...

(Heat makes fluid break down into "nothing")

And try never to get a pre-87 700r4. Those had early design problems that give them an early death.

FAST RS...what throttle position does it buck under? Cruise? Deceleration? Lockup will usually be around 40-45 mph. My Camaro locked at 40. As I teetered across 39 and 41, it locked and unlocked...but it wasn't a hard buck...just a slight smooth jerk and rpms going up and down.

devianb

I guess I lucked out by having an 87. I'm still on the original trans without any rebuild. I drive it hard on occassions and its still holding up well.

AGood2.8

Yep, here's a chart for everyone.
Also fluid pressure has alot to do with it . boosted pressure will prolong life of trans, however, firmer shifts can make the rearend go boom quicker if that is not built as well.

bes217

I beat the crap out of my tranny and it has never mis shifted or slipped or given me any problems at all. When it shifts it is super firm and grabs hard. My car has 73000 miles and as far as I know the fluid probably has never been changed.

Gumby

Your headed towards the danger zone. Most say not to even tihnk about changing the fluid after about 75,000 if it was not change on a regualr basics. most are good for 100,000 but the problem is unless you see it pulled, most junk yard ones with have near 100,000 to 200,000 when ya buy it for $100.

I think the basis on the no changing fluid theory is that the fluid already as bits & peices ofthe clutch paks floating around in to to provide friction. chamge out that fluid, & well, no moe friction & the clutch paks start to slip & finally go.

FAST RS

it bucks at 44-47 MPH and at around 75MPH i have noticed basicly when ever my car is at a steady 1500 rpm give or take a 100rpm that it will buck like its moveing forward and back. It does it when i have y cruse on or when i just have my foot on the gas for a short ammount of time travleing at the same speed and at 1500 or so rpm's

TomP

Next time it starts "bucking", keep cruise control off, and with your right foot "constant" on the gas pedal, touch the brake with your left foot- just enough to turn the brake lights on, but not enough to slow the car down. This will disengage the TCC solenoid, and rpm's should go up a few hundred. If the bucking stops, you know that it was just the TCC getting confused, and engaging/disengaging.

They used to make (and I'm sure they still do) a TCC delay harness that goes between the TCC connector and transmission; or, just accelerate a little more, or, always tap the brake when you want it to stop. (I always tap the brake a bit if it gets on my nerves).

2.73's Suck

why cut the whole drivers floor out?

FAST RS

I have tried that before at first i thoght it was a vac leak with the cruse but it wasent even with the switch off it will stiill do the bucking thing. I will try what u said tho

Gumby

Cause it wont cost any more and its 100% easier to just have the guy at the junk yard cut the whole driver side floor pan out and have it all in one piece to mess with at home.

unless you like crawling around and uder cars in the junk yard. And they will charge you more if they gotta crawl around and under it.

Same here. I have a 1987 700R4 and I was changing my fluid and gasket/filter the weekend before last. My transmission is in great shape. It shifts like new and has never given me issues.

Eventually I am going to pull it for a high performance rebuild.

TomP

Adding an aftermarket trans cooler to the existing factory cooler will also help keep the trans fluid cool (and happy).

I have a B&M Supercooler -and- a Summit remote trans filter (uses a big AC PF1 filter). If you install a remote trans filter, you still must retain an in-pan trans filter- the in-trans filter doubles as the fluid pick-up. The remote trans filter adapter has been tapped for a trans temp gauge; right now it's got a brass plug in it, but eventually I'll add a trans temp gauge. I just have to figure out where the heck to put it so it looks good.

It's kinda like using an extra strength Trojan instead of a generic rubber.

NHRATA01

Just curious, what temperature does a 700R4 usually run at in normal driving?

87CamaroMan

Well I posted on this about two weeks ago saying I blew 2 700-r4s' now the one thats in there now is starting to go... I am begining to really dislike this car..... Well the person who designed the tranny atleast... I'm gonna park it this winter and just rip the whole thing down and start over and put a T-5 in it. This will be three 700-R4's for me in the matter of 6 months. The fact the I have a 3.4 in it might have to do w/ something.

Mikes86SC

Yep. Everyone swears my IROC has a shift kit, since it does have very firm shifts. Spent $650 to rebuild my rear just last week.
