    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

    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 the 4l60e has been replaced by the 6l60e which is in the corvettes etc.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.
    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?

    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.

    x2 a new beefer sunshell with better transmission cooling passages

    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.

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

    here
    here

    "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 ?

    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

    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 !!!

    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

    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 ?

    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

    3rd

    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.

    Tranny sucks

    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
