Not shifting from 1ST WOT

[martinique78]

My 47RE wont shift if my Quadzilla tuner is on anything other than the stock setting at WOT from a dead stop.  If I let off just a bit it will shift.  I know its not slipping, almost feels like torque management de-rating the engine till i let off.  Any help is appreciated.

The best man to talk to here is @Dynamic about the transmission.

Sounds like a TV cable adjustment issue in my uneducated opinion. 

 

Other then that have you done a band adjustment recently or checked it? I know I got mine too tight once and it wouldn't shift outta first at all so could be that.

What is your transmission configuration? Mods? Converter? Stall speed...?

Trans is pretty much stock.

 

All new bands and clutches before winter.  

 

When it doesn't shift it's like i hit engine speed limit before it can shift.
