Whenenver I try to amnually shift my tranny, it hangs in 1st gear, and i have to let off for it to shift to 2nd gear. Is this normal w/ this tranny?

I would NEVER manually shift any automatic transmission VERY BAD!!!! For it hanging in 1st I can only think that if you put it in drive it will hang in the higher RPMS for a longer amount of time. If I am not mistaken I would not doubt that you may have broke something in you transmission if you manually shift it all the time. Devin

Auto the car shifts, manual you shift, sounds like you need to get a manual for the fun factor. Ive know people to think that its ok to do that and have seen some nasty blown trannys. Dont do it, stop doing it, or if its too late which it sounds like it may be get it fixed, and dont think about doing a swap, its too much money and too complicated. Good luck man hope you get er fixed.

What the hell? Manually UPSHIFTING your transmission is relatively harmless. It's not going to cause much more added wear. I believe manually upshifting a 4L60E does use the overrun clutches resulting in a more satisfying shift and subsequently slightly more wear, but it's not going to break your trans. What do you guys think paddle shifting is? It's manually upshifting. It's manually DOWNSHIFTING an automatic car that is very bad. Manually upshifting isn't that bad, and any trans sponsor will back me up on this. You guys are talking a lot of crap here.

To the OP: under heavy throttle, does it only hang when manually upshifting and it shifts just fine at WOT? Does it bang the rev limiter or just hang there and never touch the rev limiter? I strongly suggest you post this in the Automatic Transmission section, but it sounds like to me a shift solenoid may be sticking. But what do I know? I'm scared of automatics.

Hey chocotoco I misread his post, i am sorry yes you are very very right manually downshifting an auto is bad. Devin

There is no such thing as manually shifting a 4L60. There is only selecting a gear or range. This should not be confused with shifting. The shifter is a phyiscal logic selector that works with the computer logic.

When the trans was designed there were needs to be addressed like pulling a load in hilly condition, low traction and varous others. Hot rodding and getting a fast launch from a roll were not in the plan.

Cars that come with paddle shifting have new logic in the shift programs that work with the throttle, the timing, fuel flow, speed sensors, line pressures, clutch positions and more. These are used in a way to give the driver the sense of control (not actual control).

In reality though if you want to shift get a manual. If you want your auto to shift differently, modify it!

Just put it in drive and push the gas. You'll be 100% safe then. You'll get the best times by just letting the computer do the shifting anyways

If its bad to manually shift an auto why do most drag racers not have problems when shifting the auto when racing down the strip?

CodeRed2000SS

because "drag racers" aint drivin stock autos. manually shifting in a 4l60e is pointless unless ur trying to trick everyone in town to beleiving u got a 6spd, but why u want to do that? just put in in D and b***h slap all those 6spds haha

nhra cars like top fuel and funny cars arent automatic they are all manual they only use the clutch to take off and then the tranny gears are designed just to slip together without grinding

Because they are built transmissions and not stock from a production car

Manually shifting an auto doesnt hurt anything! Its more harmful to leave the car in overdrive and and hit WOT. The reason your trans wont shift, is because you have the throttle wide open. The computer thinks your trying to stay in "passing gear". You can tune the pcm to adjust your 4l60e. Thats normal, thats why people get tunes.

Thanks for the lesson there chief. I wasnt talking about the Professional cars.

Not all of them. I know a lot of people with stock Glides and Turbo 350s. They dont have problems. The one with the Glide is going on 3 years without touching it.

upshifting for a 4L60E is completely controlled by the PCM. For example..if you start off in first gear, and go 3/4 throttle...as soon as it hits 2500 rpm, bump it to 2nd gear...The transmission is not gonna shift immediately to 2nd gear just because you bumped the shifter into 2nd. This is because at that throttle position it knows, to hold 1st gear until a certain RPM/speed..You moving the shifter into 2nd gear is just giving "permission" for the PCM to shift into 2nd gear, but that is only gonna happen when PCM feels its necessary to make the shift.

When racing, be in 4th (OD for Camaro, D for Firebird), but during regular street driving, I'd be in 3rd (D for Camaro, 3 for Firebird).
