How the hell...

Call me an idoit, but exactly how does an auto 4speed(700r4) tranny work? Last night i took my brother out on the highway cuz he wanted me to go fast. What happened was i chicken out when i got to 80 because the damn thing was redlining at 5500, yellow begins at 45 and red at 50. I was scared i would of blown the motor or something would of broke. 1st gear definitely works, it shifts into second perfectly at 4500, but it seems like there no 3rd, or is there? Could someone explain to me how the 700r4 works? I just don't wanna break anything.

Count hte shifts.... Check to see if your in O.D... What rear end gears do you have? Anyone who has the same setup, is he stuck in 3rd?

2.73 is stock for my car. I figure if you put in drive, it would shift through all 4 gears. I start from a dig, it definitely shifts into 2nd, but when in 2nd and when it should shift to 3rd, damn thing keeps revving, all the way up to 5500 (is that normal), i just don't wanna blow anything.

Well, if you don't feel the shifts then it probably isn't shifting out of 2nd or 3rd. That would definately cause it to rev way up and not go much faster. Like Xeno said take off from a stop sometime and count all the shifts to make sure it's shifting, otherwise it's prolly time for a rebuild.

Damn, i was hopeing i didn't have to do rebuild yet, so i'll try this afternoon when i get of of work. I've plently of people be able to get there v-6 3rd gens up into the 100's but i haven't even been able to break 95, cuz it looks like the shits gonna blow, but it is cool to redline your car, the last time i did that, my motor seized up while i was on the highway, not cool.

If you put in in drive it's only gonna go through 1-3 and not engage the OD band.

Also I think a stock 700R4 won't shift into OD at full throttle. Some1 correct me if this is wrong.

I don't see why the tranny woudn't shift if the R's are that high unless there is something wrong with it. But you could try letting off the gas when you have it up that high and see if the transmission shifts.

Well last time I tried going the fastest on my car I got to 105! and you havent even borken 95, shame on you. Also OD doesnt kick in at full throttle only at 3/4 throttle down, but you can make it go like that, just needs some work.

92, do you have a 305? If so is it TBI or TPI???

Havent you read my other thread? R.i.p.? I have a V6 which is now gone to hell, but I wish it was a 305 or 350 tpi that worked.

Sorry, I don't memorize you life, I have better things to do... You got your sixer up to 105 and he can't hit 100 with a 305? I think there is something wrong with his transmission, but that's just me...

The hell's your problem? anyways yes if his cant make it up 100 then the tranny needs work.

I'm startin to believe the tranny needs work. I went from a dig, it shifted into to second but once i was pretty much redlining in 2nd no shift, biotch keep wanting to rev, got all the way up to 5500, i must say it did sound pretty damn good though. It still has an amazing pull, just afraid somethings gonna blow. Really sucks though.

My problem is that you're coming down on me for not knowing that you have a v6, like I should have read your other thread and commit your car to my memory. Like I said I have better things to do...

On your console, how do the numbers read?
1 2 3 D N R P

or

1 2 D OD N R P

(I have a 5-speed, so I dont have this problem. Last automatic I had was a 3 speed)

I got the 2nd one you posted. Never tried driving in OD though. I might give it shot tomorrow (gotta get some gas, gettin paid tomorrow!!)

lol you never drive in overdrive??, wow, well you wont have to be spending as much at the pump

Well not to sound like an idoit, but when should you drive in OD? I figured on a highway or something like that, but would it be good on regular streets? Would it also allow me to get up to higher speeds, i just wanna see what my car is capable of.

Always drive in OD (I do at least). The OD gear is a less than 1:1 ration, dropping your druising RPMs saving engine wear and gas. It's like 5th and 6th gear on manuals.

yeah, it doesn't hurt to drive in over drive unless you will need the r's when you are going faster, all other times it saves gas. And putting it in OD instead of D won't fix your problem if it isn't shifting out of 2nd they both do the same thing until it shifts into the OD gear.

also. if will be of any help, when in drive, i can just push the shifter up (without pushing the button top down) into OD. is that normal?

yeah

Actually no it isnt, what you have to do is get under your car and connect your cables that go from your shifter to your transmission, they're just loose and if you dont do it now over time it will get worse and you wont be able to get out of park (Happend to me). The only problem is that I dont know EXACTLY where it's at because I wasnt around at the time when it was fixed, but I know the problem.

A 700R4 or any non-electrical OD auto should not be put into OD with speeds under 55mph. Your are not creating enough line pressure and the OD band which is just a brake material lined strap that clamps the direct drive hub will not fully engage and be in a state of constant slippage wearing it away when under 55-ish mph.

oops forgot that I have an electronically controlled tanny and he doesnt.

Rally sport 92... yes it is. N/OD you dont have to press, and d-od upshift you dont

told ya

ive never heard that before, i always drive in OD, i only use D to downshift when passing on the highway.

try slowing down from 60 mph and down shift manully and count the gears

the overdrive control and the torqueconverter lockup is controled by the ECM. the first three gears are not.

dude, always drive in OD unless you are racing a 1/4 mile. Also a 700-r4 will go into OD on WOT. It won't lock up the converter though.

and yes it is normal to be able to shift into OD from drive without pushing the button, you should be able to go all the way into neutral. the button is really supposed to be a reverse lockout.

I'm an ass!!! Last night i took to American Legion Highway (my test zone when i wanna test something out) to see what up. Well, i put it in drive to get it up to around 55, it shifted correctly, then i through it into OD and it went through all gears!!! I was at 90 something at only about 3500 rpm, not redlining and i still had more pull. Guess my problem was that i needed to learn how to drive, learn something new everyday huh. Guys i apologize, i'm an ass. It did also go through 1-3rd yesterday when i was driving, i counted and it went into 3rd. It's weird because my car is so much like a female, it acts good when it wants too but acts like biotch the majority of the time, i still don't get it.

THat's what the OD gear was designed for haha... its ok better learn now than later

It was a major oversite, but like you said, better now than later. I actullay might be able to take that eclipse now :evillol: .

I do not believe the line pressure of the 700R4 is controlled electronically like later GM/Ford overdrive auto's. This is where the problem happens cause the line pressure is not enough to fully engaged the OD band accumulator piston.
