Changed diff ratio and rescaled as usual, reduced shift speed and changed rpm points and still the same. Will change normally at part and medium throttle. If the solenoids have a resistance between 20 30 ohms, they are good. You can test shift solenoids using an OHM meter. The coil wire can go bad in a couple of ways and additionally, the plunger could also get stuck.

I know that I'm not really addressing what is wrong with your tranny but hopefully this can shed some light as to what might be going wrong with yours. Built 4l60e trans won't shift into 3rd gear at full throttle after 3.9 ratio diff change. Most of the issues with a 4L60E 2-3 shift solenoid are because the coil wire goes bad. Everyone tried to scare me into thinking that the tranny was completely fried and that wasnt the case. one of the shift solenoids, Force motor, TCC lockup ect.and not in the clutchpacks or deeper in the tranny. So to tell you the truth, I truly think the problem was in the electronics in the valvebody i.e.
When I got it back it shifted just fine, no problems whatsoever. After that RPM goes to 3000 - 3100 but car won't accelerate no more and I get 62 mph and 3000 - 3100 rpm. When I put shifter into overdrive position and start acceleration trans normaly shifts through 1-2-3 gears. About two weeks after the shiftkit install, tranny started acting up (I believe it was because I overtorqued the valvebody and locked up valve) so I decided to pull it and have it professionally rebuilt with a better sprag, beast sunshell ect.I know the guy pretty well that went threw it and he told me that the 2-3 clutch pack was fine and that all the solenoids, TCC lockup valve, force motor and everything in the valvebody looked and tested good but he told me he would replace all of them just to make sure that we corrected the lazy 2-3 shift problem. Hi everyone, I have a problem with my 4l60e tranny in my 96 Chevy Tahoe 5.7L Vortec.

So I decided to install a transgo shiftkit myself hoping that when I was in the valve body I would find something that I thought could be causing the lazy shift problem.To no prevail I didn't find anything and even with replacing some of the valves in the valvebody (replaced the valves that come with the shift kit to replace) it still did the same thing. This kit can be installed while the transmission is in the vehicle on 1993-2006 models only without the. I asked around and everyone told me "it HAS to be that your 2-3 clutch pack is toast." (I didn't believe them because when it would finally shift into 3rd I could step into it really hard and I couldnt get it to slip in 3rd gear which tells me that the 2-3 clutchpack is doing just fine). Does not fit 1993-95, 2005 Corvette or hybrids. I have a 1994 K1500 with the 4l60E and mine basically did the same thing for quite a while.It would not shift into third until I got out of the throttle and let the motor rpm come down, then it would shift with no problems.
