The 4l60s take longer to shift 2-3, because more stuff has to happen in the trans in order for that shift to happen. Yours seems like its taking a while though, just keep moving the shift rpm/speed down til it shifts where you want it.
On a side note, I've seen some recommend putting the shifter in '3' until it shifts into second then move the shifter into 'D' before it shifts to third. I've never tried that, but someone said it worked for them.

I had/have the same problem. I have fixed it by keeping the Rev Limiter at 6500 but lowered the 2-3 shift point. I used to have the 2-3 shift raised 12 mph and now it's at +8mph (over stock). I still need to lower it another 2/3 mph and it will be perfect.
It's keeping me from breaking into the 12s. My MPH at the track are 110 and some change but the time is 13.45 from all of the "flubbering" (can't think of the appropriate word).

i have the same problem, I have hp tuners and i moved my shift point down to 50 mph. From a 45 mph roll it shifts fine now, but when i go from a dead stop it will hit the rev limit every time.. Could my 2-3 shift solenoid be the problem?f

me too 2-3 hitting limiter
I have the same issue to. I have a new stage 5 trans 1 month old rated to hold 800 hp from local shop. It has all the bells and whistles in it (4l60E). I noticed when I race it in 3 it will bang the rev limiter for the 2-3 shift for a second then shift but in D (overdrive ) it never does it. I have a 3200 vig stall as well. Speed Inc tuned it last year with the old trans and the trans shop didnt change the tune. Hell I just been racing it in D, but wonder how much slower am I in D vrs 3. I dont feel any slower and the car pulls very hard with the new trans and shifts VERY firm. any input???

I have the same issue. Had my car tuned a couple weeks ago and still was not able to get it to shift even after lowering the shift rpm down to 5100rpm.Im not sure if the mph was touched or not though so I might try that to along with also changing my fluid. Fluid looks fine but that doesnt mean its still good.

Never mind...i thought you had a after market cam in there? I'm told our cams stop making power after 5900 rpm, so raising the rev limiter is not the way to go. I guess it's lowering the rpm shift points?

I have the same problem and had it for a while now, only i do think is my tranny for the reason that when the car is cold, 2-3rd goes in like it should but with a slight delay... when the car is at normal warm temp.... 2-3 shift hits limiter... also... when tranny is place in 3rd (D) i have bad vibration in the tranny... wich i read here that it might be clutches slipping...

We have tried to program it out and sometimes it seems to have helped, but then it does it again. Fluid and level are good, I even added an extra 2qt pan fot the hell of it.

Damn, I was just reading this and decided to say I have the same problem with 2-3 shift on mine also. mine is a fully built 460le also. Shift points were originally set at 84mph when it started happening on nitrous only. (Motor runs were fine) We dropped it to 78mph and it shifted fine but i felt it was short shifting and I was losing mph on top end. So we bumped it up 3 more to 81. Same thing happened again bouncing the rev limiter.
Seems as we all know that nitrous will always find a weak link. I think i will just try to have it refreshed and gone over...If that dont work I just may have to go TH400 and be done with it, but i think i would really miss an overdrive. Just thought I would share.
Seems alot of us have this Problem!

Add me to the list also. After I did gears and stall it does same thing when I go WOT for the 2-3 shift. It hesitates to shift and then it'll hit off the limiter. I'm guessing its the bands. Going to probably get a FLT tranny and have the yank ss3600 refreshed to be on safe side. Even though its been tuned I'll get it re-tuned again.

Mine does it one the street. Everytime I go WOT it will bang the 2-3 shift. Fluid is full and still in good condition. Maybe its my converter? Is having a really loose converter a problem that could cause this? I have no idea, just throwing that out there.
BTW: If I ease off the throttle and get right back in it, it will shift.
