4l60e shift issues after rebuild

[onedbdred]

I was wonder if anyone had thoughts around this issue I am having. I overhauled this transmission on my 2005 chevy silverado z71 4x4. The reson for the rebuild was I was hearing a metal on metal sound, but still performed like it should.

After pulling it apart all I saw that was an issue was worn out 3-4 clutches. I went ahead and rebuilt it. After the rebuild was done I took it on a test drive and it would not shift out of first on its own, you had to let off the throttle and it would shift, but never into overdrive.

The next day after that I decided to go for another drive and I got a couple of blocks away and seemed that it would not shift out of 1st at all and after you got to about 20 miles an hour it gives you a netural effect that you cannot get out of. he only way to get it to move again is to come to a complete stop and not go over 15-20 miles an hour and i got it to limpo home. I was wondering about the pressure, so I tapped into the test port. Here is the specs.

P,N,OD about 65-70 psi
R about 100
WOT in 1st about 195

Anybody got the actual specs of what it is supposed to be?? I would apperciate any thoughts around this. I am having one heck of a time with this thing.

how many of these transmissions have you re built ?

when something like this occurs you know what this means ....

Did you remember to plug all the electrical connectors back in?

Did you remove the valve body at all? If so, did you install a new gasket and torque everything down right?

Does reverse work?? Will it pull good in reverse?? How did the sun shell look?? Did you remember to put the band anchor pin through the bottom of the case before you installed the valve body?? (This is the little round button that slides through the case which anchors the band) Heres a pic of it.




Did the band servo pin engage with the band strut??
