  • Has any one heard of a way to make the 4L60-e act like this...

    A friend wanted me to ask yal this, personally I have never heard of it being on a camaro or firebird from 98-2002...

    Someone is selling a firebird and has been known to shift his gears as if it was a manual even though it is an automatic.... I don't think that the automatic was made for this, right? Does he possibly have a sequential shifter of sorts?

    What are some of the problems he might have with his (I think)2001 Firebird T/A for him to be selling it?...

    Thanks...
    Thanks

    well just coz he shifts it like a manual doesn't mean it actually does shift like a manual. The 4l60E is electronically controlled when shifting, so put it this way, if he was holding it in 1st gear and was full throttle and shifted to 2nd under the usual 5600rpm mark, like say 4000rpm, the car wouldn't shift from 1st to 2nd until it reached the 5600 rpm anyway, so it wouldn't make much of a difference.
    The difference is that he can hold it in 1st gear till it maxes out on rpms and knocks back, also he can hold it in gears under low acceleration. Thats the difference as far as I know. Anyone correct me if i'm wrong here.

    Oh some problems he might have..... well if he downshifts manually he could have worn out his tranny really bad over time, which really affects shifts and makes it so much weaker in the long run. Using gears to manually shift autos can wear out your tranny in as little as 2 years from what i've heard. hope i've helped.

      Before you post check out your info.......


      He may have a tranny with a full manual valve body installed. A full manual valve body gives the driver control over what gear the tranny is in. You MUST shift it manually if there is a full manual valve body. Whatever gear you chose is the gear the tranny is in. If you start out with the gear selector in 3. - it will start in 3rd gear. So, you have to drop the selector into 1st and manually shift through the gears. This is a pain on the street, but is nice at the track because you can chose very precise shift points. It does not have any adverse effects on the tranny, unless the stock shifter is used and that will eventually wear due to the constant shifting - but thats a stretch. If he has a full manual valve body - he probably has other work done on the tranny - pressure mods, higher stall convertor etc...

        Some people are convinced that shifting a stock automatic equipped car manually has the advantage. This isn't the case, but people are hard to convince. They are best when the computer shifts. If he has a stock trans, engine braking by downshift has been known to tear up 4L60s. So, the transmission issue is difficult to really give you any insight without knowing more about the car itself. The other guys have already covered the performance possability.

        The other stuff to look for: Warped rotors, valvetrain noise, bad headlight motors, worn drivers seat, leaks from engine/trans/rear.

          Maybe I misunderstood the question here......did he say he HAS to shift the gears manually or he just does it on occasion?

            He shifts it like a manual all the time, but the car is bone stock right down to the shocks and intake and exhaust and gears. So I don't think that he has modified it any more.

            Thanks for the info. though...

              OK, so its not a full manual valve body. I personally dont think that you will hurt anything as long as you are shifting at the right time (ie. not dropping it into 1st at 50mph).......but obviously others disagree. So, take it as you will.

                Thanks but after looking more closely at it, my friend (said) they saw some, "...flood damage to the under body structures..." word for word... But I don't believe her but I rather she gets a compact in that case because she is abusive even to a little 3 cylinder Metro...

                Thanks though...

                  hmmm so it turns out that you were wrong and i didn't make a mistake........... maybe you should check your info before you post instead of assuming he had a manual valve body and flaming me for it.

                    Listen....I wasnt trying to flame you. All I was saying is check your info before you post, you may mislead someone. I did not print any mis information. I listed a POSSIBLITY, not knowing anything about the car.....that possibilty was wrong. Dont jump on my case. If you would like to further investigate the short comings of your post and open a debate on automatic transmission theory, let me know.

                      lol. look i'm just here on these forums to learn as much as i can and once in a while i try to help or add my 0.02 cents if i can. If you did not mean to flame me well...........Put it this way, you coulda taken a much better approach in posting your first reply instead of just telling me off, coz i don't take kindly to that. No i don't think i could debate you in whatever coz i'm still young and learning as much as i can, but thats besides the point. Like i said, you shoulda handled your first post better before telling me to go check my info. Anyway, no hard feelings here, like i said, i'm here to learn as much as i can about my car and cars not to pick fights online.

                        oh by the way, what did you mean when you said "the shortcomings of my post" ? was i wrong in saying that if you downshift a lot on an auto tranny it will wear the tranny out ? just wanted to know is all coz i got that piece of info from many many posts about this specific topic in camaroz28.com forums so i just want to know is it wrong? Also I thought the 4L60E's shift automatically at the optimum points no matter what, i also got this from reading many different threads about this topic. So was I wrong about this too? thanks for the info.

                          A little off the subject, but I have had 3 4L60E auto transmissions and the thing I hate most is when you step on the gas and the car just falls on its face. What I mean by that is this, you will be rolling along, and if you catch the RPMs just wrong when you step on it, it will not even down shift. It just stays in the same gear, but at full throttle. I just hate that!!!!

                            Well, it depends on what you mean by downshift. If you are referring to downshifting manually to use engine braking, then yes I have heard the arguement like Joe alluded to, this MAY be detrimental. I personally cant see how this wears anything unless you are downshifting when you shouldnt (ie. RPM's too high).

                            If you are referring to downshifting manually under acceleration, then there are no adverse effects. Just like Jspeed97 just mentioned, there are times when the auto tranny doesnt shift when it should. There is no harm in downshifting manually in instances such as these. Again, if your dumping it into 1st at 50 or 60 mph, of course your gonna have troubles.

                            I guess to summarize, as long as you are placing your downshift correctly, your not gonna hurt the tranny. But, you gotta remember, the 4L60E is inherently weak to begin with.

                              Personally, I've been through 3 trannys in the 50,000 miles I've owned my car. I burned out the first one by using engine braking to slow the car too much. The clutches burned out due to low line pressure not holding them, which is why in a stock trans you don't want to use engine braking. Technically I completely smoked the overrun clutch (which is responsible for engine braking in a 4L60), and could only have worn out by excessive engine braking.

                              From what I have experienced, the 4L60E is temperamental unless you use it exactly how it was intended. Even running it up to high speed can be detrimental as it still suffers from a low pressure condition under 4th gear lockup (present since 700R4 days).

                              I have also heard that manually upshifting a 4L60E results in temporary line pressure drop which will eventually burn out the trans. I have not heard of any ill effects from manually downshifting under acceleration.

                              Just thought I'd add my 2 cents in-
