Am I shifting just before the end of my 1/4? I have a 3600 stalled, 3.23 (GU5) geared, 4L60E and shift points set to around 6500. Makes just under 400 rwhp, 400 rwtq.
I don't know why the hell I wouldn't have noticed before, and I can definitely take a look next time I'm out at the track, but am I shifting just before I cross the traps? I always leave the gear selector in OD, just because I was always told by forum goers that it didn't matter. From what I understand, there is no reason the car would shift into OD right? Come to think of it, it does feel like it's nuts get cut off just before I go to cross the traps (maybe half to three quarters of a second before I hit the end).
Anyhow, just looking for forum member verification before I go out to test it for real.

With 3.23's and what I'm going to assume you run with is around a 26" tall tire @ 6500 you should be around 145-150 depending on convertor slippage so I'd say no unless for some reason its set to shift early into OD at WOT.

That's what I was getting to mainly, to see if for some reason it's shifting early into OD. I will keep it in third at the track to rule out shifting into OD. And see what happens.
Was just looking to see if it was possible or not.

Correct, 26" tall tire, forgot to add that.

I thought converters weren't supposed to be locking at wide open throttle? Either for or against my benefit. (unless instructed to do so... thinking more along the lines of having it on the dyno, etc.)

You are correct on that, they shouldn't unless tuned to do so but I have seen one in a truck before acting up and locking under WOT even when it was not tuned for it. Not sure what he did to get it fixed as that was years back but weird things can happen.
