for some reason my 1-2 shift seems to be softening up lately. Part throttle shifts are clean and crisp as always, WOT 2-3 shifts seem up to snuff, but my WOT 1-2 doesn't have the punch it used to, in other words it seems like it's taking longer to make the shift than usual, and in addition to that, I have been experiencing increased driveline slop(previous post). Any ideas? Is she showing the first signs of heading on her way out?

 

You have the 4L60E or the 4L80E in that beast?

 

80 my friend

 

dumb question but does your fluid show any signs of internal wear? Trans temps normal?

 

good to roll on both accounts

 

guess I'll just keep hammering on it until it gets better or breaks

 

words to live by

 

 

I wouldn't think you would have any problems with the 80E. Check and make sure your fluid isn't low. When I went to the track last time my 1-2 shift was a little sloppy, and I went home and found that my fluid was just a tad low. I put another half-quart in and the 1-2 shift firmness came back.

 

I'll check again but they are not what they used to be, although I did a few almost WOT runs today and it felt ok but still not like it used to feel.
