Default 3-2 downshift vs 2-3 up

I think we have a seperate solonoid for 3-2 downshift and 2-3 up. My 2-3 up is perfect, no limiter, no slip at all. if i'm cruzing at 60mph and go WOT it will slip a tad going in 2nd(almost feels like turbo lag) Could this be a hanging solonoid or is harder for a 4l60 to hold the power when downshifting? Its always done this since I had my converter installed. approx 10k miles.

If there was a problem with either solenoid it would set the SES light. Mine did this.

I had a solonoid slowly fail in my 96 and never had an ses light. If its hanging half a second or so I dont think the pcm picks that up.

Yeah, my 4th to 2nd downshift is wayyyy sloppy the closer I get to hitting the top of 2nd the worse it is...ex: 60mph the downshift is fairly tight...70mph it will slip big time and hit the rev-limiter on occasion. Anything over 70mph will only net you a 4th to 3rd downshift(3.23's) and feel pretty sluggish, so at 70mph with 3.23's you are hitting the very top of 2nd gear when you go WOT.

I have built a few transmissions and i think u are barking up the wrong tree.
maybe you should have someone look at the overrun clutches inside the trans
i bet they are burned

just a thought
