4l60E

[mrwdjv]

This is the transmission in my car....is that good?

[irishpenguin13]

anything is good if you take care of it.

[irishpenguin13]

u might wanna put this in the drivetrain section under automatic transmissions.

[SteveCZ28]

well jee....every other automatic transmission in a fbod just happens to be a 4l60e so im gonna take a wild guess and say its a good transmission? you know there are other forums on this website other than anything goes...last i knew there was a specific drivetrain forum for these kind of questions...i may be mistaken though

[irishpenguin13]

ok, im trying not to laugh. but this isnt helping...^

[SteveCZ28]

:D haha

[mrwdjv]

Sorry guys, I thought ya'll knew everything and this would be my best bet for an accurate answer!

[irishpenguin13]

im thinking she just posts just to post.

hey..lets not be a dick...and some people will argue that the 4l60e is not a "good" transmission for the f-bod ..since it needs a good amount of internal work to make it handle power/torque

[irishpenguin13]

to what "is that good"??? i dont know what to say to that.

[mrwdjv]

People who are looking at buying my car have asked what transmission is in it. I had to call GM to find out. I didn't know if that would hurt or help the value.

:iagree:
Of course the 4L60e is very debatable on how tough it really is. I paid $3k to make it as stout as possible and no issues so far. I don't race it all the time nor have the line pressure's set high.

The TH400 and 4L80e are stronger transmissions but they have a few headaches of their own. But then again any transmission will have some temperament, nothings perfect.

[shady milkman]

the 4l60e stands for 4 speed- longitudinal- 6,000 gross weight (of the vehicle) - E for electronically controlled.

the 4l60e is a good transmission with the proper maintenance.. it is increadabiliy picky on fuild amounts..just a smig to high or low will really wreak havoc on your transmission. the 4l60e has been replaced by the 6l60e which is in the corvettes etc. both are good transmissions..but when modding..a heavy look needs to be had at the transmission..a build up of the transmission is always a good idea. The 4l60e is prone to overheating and causing damage due to poor clearances for proper fluid flow. for a everyday DD with little to no mods a 4l60e is perfect and pretty trouble free..just make sure to not manually shift the transmission.

2 transmissions in these cars that had the v8...t-56 (6 speed) and 4l60e (automatic)

Overall it's a really good transmission for a stock fbody. Just when you start pumping 600+ rear wheel horsepower into it....then it's getting questionable. But hey, that's alot of hp. :Ohno:

right on, my car is as stock as can be and never had problems yet.

there were only 2 transmissions available with the 98-02 f-bodies..the 4l60e (also called A4) and the t-56(m6). 1 automatic and the other manual

in general with any performance car..manuals will command a higher resale value.

there are a set of rpo codes on your driver side door..they are 3 digit codes...you can look them up on line and it will tell you every option that was selected for the car.

[mrwdjv]

The 4L60-E is an automatic shift, four-speed overdrive, longitudinally positioned transmission. It is now considered to be the best rendition of the finest overdrive automatic transmission ever produced.

:yup: i know the big problem is the trans fluid clearances between parts..it can lead to heat related failures.that and the bands and input shaft... that is why when the time comes.. i will be sending my trans to FLT to do the stage 2..maybe 3 for mine.

i hink we should stop now...she undertsands she has a 4l60e (a/t) thats about all shes gonna understand. she wont be able to fathom all the info bout fluid levels and possible overheating due to small passages for the fluid to pass thru..gotta explain it like your explaining it to a kid here

Be sure to put a big trans cooler on there too. Also putting a bigger pan on can help with cooling. I put a 4L65e trans pan (from a truck I think) it holds another quart and 1/2 over a stock pan. The B&M ones hold more fluid but also hang down too far for my lowered car.

FLT is really good. That's who built Ed's trans and he hasn't broken it yet. Although he hasn't driven his car in over 2 years. :sillyme:

Good job on your explanations Jordon....you've done some solid research. :thumbup:

yea ..when i go get stalled i will throw a cooler on..and a temp gauge just so i know...i heard about the pans..but i am always worried about ground clearance since i DD my car through winter etc. ..once my car becomes a warm weather car...i will probably swap pans

shes selling her car anyways so we dont need to give her crazy ideas of building her trans all up and adding the trans cooler and fun goodies..she doesnt undertsand what were talking about again. so ill just leave it at that....you haz automatic...put lever in the D with the circle around it and push the go pedal

i have occasionally shifted manually at the track...i got decent times..but the 4l60e is not made to be shifted manually and it messes with the stock parameters for the transmission

? can the 4l60e be replaced w/ a 6l60e ?

I'm assuming 6l60e is a 6 speed trans. I would love to have 2 overdrives like the M6 guys have. is the 6l60e a auto M6?

[allbaugh_04]

Yes it's a 6 speed auto

[bills98ta]

The weak points of the 4l60e is the clutch basket and valve body plate. Put a Beast sunshell ( basket ) and a transgo plate in, she'll last !
I'm still running the original 4l60e in my 98 with a 4600 stall, launching it hard every time. Plus, it's programmed where to shift, so I leave it ion OD down the track.

They seem to be hit or miss, some blow up with stock power while others are running in the 10's on a stock tranny. I put on a good cooler, deep pan and keep the fluid fresh, hopefully it lasts.

auctually (not being a dick) the 60 stands for HP rating add a 0 to it to get 600 and divide by 2 to get the HP rating 300hp.

[shady milkman]

well i have to disagree ..everything i have ever seen about the 4l60e says otherwise

here (http://superchevy.automotive.com/101558/sucp-0904-chevy-4l60e-transmission-build/index.html)
here (http://www.novak-adapt.com/knowledge/4l60e.htm)

"The 4L60-E derives its designation from its specifications: 4-speeds, Longitudinally positioned, 6000 lbs. GVW, Electronically controlled, although the transmission sees factory service in trucks up to 8600 lbs. "

"Believe it or not, "4L60E" actually does stand for the specifications of the trans and isn't just General Motors trying to mess with us-4L60E stands for four speeds, longitudinally positioned, 6,000-pound GVW, and electronically controlled. When the 4L60E transmission was phased into production, the 700R4 was renamed 4L60. Notice the missing "E" for non-electronic."

plus GM rated the 4L60-E is to handle up to 360 ft·lbf of torque..

plus dont transmissions always get rated for torque and not horsepower ?

[Cutlass]

good infor in this thread.

? can the 4l60e be replaced w/ a 6l60e ?

I'm assuming 6l60e is a 6 speed trans. I would love to have 2 overdrives like the M6 guys have. is the 6l60e a auto M6?

Its 6L80E and yes it has 2 overdrives. 0.86 and .67
Not sure on its swapability yet.

[64MonGooSe64]

So shifting a 4l60e is a really bad idea? i sure hope it isnt becuase i do (for some reason or another) shift it manually when i am, at the strip, autocrossing, and just daily driving. I havent had any problems with it yet considering the motor has seen around 6k under a manual shift and it did well and didnt sound to hurt it at all. But if this could be a problem that can get worse i will definatly stop my strange habit

[bills98ta]

Most won't shift manually at WOT. Do you have a shift kit in yours ?
I program my shift points & leave it in OD at the track. Very consistant !!!

[64MonGooSe64]

no i do not have a shift kit, but the transmission shift is VERY responsive and harly no delay, a buddy of my with a t56 and an lt1 said that my car shifts into gear faster than he could with a manual. mayb ive got a 1 off miracle auto. My 1st to 2nd is almost perfect weather its @ 2k or 6k but my 2nd to 3rd is perfect @ 6k but slightly delayed at 2k but i think thats because the tranny is checking my make sure its able to go into gear with out bogging down... u know how "smart" these trans are... hopefully im not seriously fukin something up by doing this :(

[bills98ta]

Once I added a lot of power adders, that's when I had to lower my shift point programming. It would over shoot the shifts and hit the rev limiter. Mine never did shift manually... It would bounce the limiter...
As long as yours is shifting, it will be OK !!!
Have you had it to a track to see what times it's running ?

[64MonGooSe64]

Well When im in neutral or park my limiter is at 6,200 (I THINK) but when im in Drive/OD and mash it 0-60 (1st gear) it shifts at about 5,500 every time which is like 55-58 mph, but when i do it myself i can wind it all the way up around 6,000 and ive seen the speedo at around 61-63 in first gear, u may think im lieing but some of my buddys have seen it an been like, "holy fuck u can go 0-60 in first gear", and i end up just blowing by manuals while they are shifting at around 45


I remember when i raced a buddy of mine who has a lt1 t56 and when we launched i put like 2 car lengths on him and then he reeled me back in to almost within a car but then he had to shift at i think he said 45, and while that was all happening i easily put 5-6 carlengths on him

[TOMASINO]

i have occasionally shifted manually at the track...i got decent times..but the 4l60e is not made to be shifted manually and it messes with the stock parameters for the transmission

mine has 123 and D can i street drive on 3rd??? and then D??

[qwik219d9]

when cruiseing around town I always have it in 3rd.
have been told this will limit the auto. from shifting like in 35mph traffic that will speed up a little then slow down if it;s left in 3rd it will stay in 3rd.

I leave it in 3rd entering the expressway and getting into my left lane spot, then shift to OD around 75-85+MPH

the more shifting = more wear.

Someone correct me if I'm wronge on the 3rd theory.

plus you take off quicker in 3rd & the exhaust sounds cooler in 3rd which is usally 500RPM higher than OD.

[reddevil]

I have had mine blow 3 times and the car only has 43K miles. The first was understandable since all the work I have done. But the next two times is rediculous. If it happens again Im going out and buying a better tranny to put in.

Have a builder, BUILD you one...seek out performabuilt or FLT so they can make a tranny that fits your hp needs

Yeah you're pretty much correct. Sounds like you have a specific need to use 3rd in traffic around 35 mph and thats fine. My theory is: "Its an automatic transmission. It shifts into the gear that it thinks it should be in for the best performance/mileage. If your just driving around then put it in OD and let it do its thing."
"the more shifting = more wear" is true, but its a transmission and it built to be able to shift and last a long time doing it.
Driving around in 3rd usually builds more heat in the fluid and that can do more damage then good.

[Z28_Driver]

the sun gear broke into 2 pieces in my stock trans.
after having it rebuilt i added a transgo shift kit.
i did very little manual shifting before the rebuild.
transgo claims the car is now safe to shift manually.
do you all think its safe to shift manually?

i've only done it a couple times since the rebuild and shift kit.
and it definately hits 60 in first.

[64MonGooSe64]

Ive been shifting my mine manualy for some time now, and i havent seen any signs of problems and i do not have a shift kit, I mean the way i see it is the tranny is pritty simple 1st gear is 1st gear an wont leave it, 2nd is 2nd and even from a dead stop it will try and pull away in 2nd, and drive is drive which means if u put it into 3rd and the tranny thinks this is not a good idea all its gonna do is put it back down into 2nd, and obviously OD is just another useless shift and really doesnt need to be used untill u cruise at about 80 or 90

[64MonGooSe64]

i figure if u do an adverage of 2 extra shifts every 10 miles, 1 up the gear box and 1 down the gear box, thats 20 shifts every 100 milles, and 200 shifts ever 1,000 miles, and 20,000 shifts every 100,000 miles... I just think doing 20,000 less shifts is a good idea for me, and plus u wont "burn out" ur overdrive (just use it when u need it).
