yes reverse works , I don't have any way to look at live data. I was planing on rebuilding the transmission but I thought it might have a bad soleniod

If the transmission goes to shift into 3rd gear and just neutrals, it is an internal problem not a solenoid. With a no 3rd or 4th gear complaint I would bet that you have lost what is referred to as the 3-4 clutch. HTH Vince

skip to 3:50 to see the actual effect of a 3-4 clutch failure.

if you want to hear me rant for a bit about why i am more pissed than a normal failure. just let it play from the start

Default lose acceleration in 3rd

my 4l60e in third gear loses acceleration but it doesnt drop into like a neutral but no matter how hard i press the pedal unless i stomp on it it hardly gains rpms. Even when i stomp on it it hardly gains speed.

Would a bad 3-4 clutch cause no WOT shift to 3rd? Everything at part throttle shifts fine. It just stays in 2nd to rev limiter at WOT.

What other possibilities could cause this symptom?

Most people describe a completely worn out 3-4 clutch as a shift into Neutral, just banging the rev limiter. If it stays in 2nd gear, that indicates the WOT shift table (in the tune) has too high a MPH to make a shift. This could be caused by slippage in the converter, slippage in the trans, or if the tune was just changed - a bad tune. It commonly happens after a higher stall converter is installed.

Was anything changed recently? Is the car stock?

If nothing was changed and the car is stock, it could be a slipping band while in 2nd gear.
