4L60E Automatic Transmission Shift Kit

Before you rebuild your 4L60E Transmission you will need a rebuild kit. Most higher end rebuild kits will include a new shift kit as well. An automatic transmission shift kit is only needed if you want the gears to shift sooner, but it can also reduce transmission wear by reducing or eliminating shift overlap

    i just put a transmission 3 years ago but the car sat in the garage for those 3 years and only put atleast 2ooo miles on that tranny from the dealership , now since i took it out for the road its not shifting the 3rd and last gear on a cadillac fleetwood 95 broughham .. any clues what that might be !

    Okay i have a 99 Z28. It wont shift above 2nd gear. just revs high. Which shift solenoid should i replace A or B? And on the control solenoid, one of them is spring loaded the other is not, is this normal? Thank you so so so much. Your videos are 5* material. Helped me so much!

    i have a question about the forward accumulator piston what does it do and would it cause a hard shift from 1st to 2nd under load or light and hard accleration ?

    I just rebuilt a 4l60e transmission and after installing it has no 1st or 4th gear, I replaced both shift solenoids and checked to make sure they are both getting volts to them, I took the valve body completely apart before I got the rebuild books!! my mistake!! I think I got the springs in the right places, but I can not be positive!! Somebody please help!!! Bout to go nuts!!

    All I can advise is…installing the 1-2 acumulator valve SLEEVE(in the valve body) upside down(easy to do) will cause HARSH 1-2 shift. looking up from the bottom of the v body, you should see the VALVE. If you just see the sleeve, it’s upside down.

    Thank you, I think I’m pretty handy with a wrench but I have never even seen a valve body before let alone put in a shift kit. couldnt have done it with out your videos ! Truck is doing great. no more slamming between 1st an 2nd gear. thanks again,

    Great video ! Question – how 4T-45E valve body is different from 4L-60E in terms of applying this video to 4T45 or these two more different and your video cannot be used on 4T-45 ?
