No 3rd/4th gear @ WOT, shifts normal at part throttle.
Yea, I went to the track tonight and my trans wasn't having it.
First 2 runs I launched horrible, spinning into 3.5+ 60' times...heh.
My first run was 16.534 @ 95MPH.
Back to the trans though, on my 3rd run it just wouldn't shift into 3rd gear. I shifted into 3rd at 5200RPM and before I knew it the engine was at 6000RPM and I'm like
Thinking I didn't shift it into 3rd I moved the shifter up another gear, and I was now in Overdrive. Still didn't shift into 3rd. Needless to say my rods were probably screaming for their life as my engine neared 6500RPM. Not cool.
So I got my slip, 15.1 @ 87MPH. I'm like yea, somethings not right cause I was 16.5 @ 95MPH with a 3.6 60'.
I ran again just to make sure, yep, no 3rd gear. I just took my foot off the gas and coasted the rest of the way.
So I've got 3rd and 4th at part throttle driving around, but WOT is a no go. What gives? Clogged valve body? I mean, if my clutches were blown I wouldn't have 3rd at all right? Is this fixable? I guess I'm getting a probuilt 700 sooner than I thought.
Real disappointing, I know my engine has a 13 second pass in it, trans just wasn't having it.

I should clarify, mine will not shift 2-3 or 3-4 @ WOT, only part throttle under 3,000 RPM.
My tranmission is stock, 84k on it. Any ideas?

Lack of a 2-3 WOT shift means something is going in the trans.
