47RE wont shift at WOT

[martinique78]

Hello all,

 

This has been going on for quite some time now.  It's not too often that it bothers me but it's something I want to address come spring. 

 

Whenever I take off from a stop hard and i mash the skinny pedal to the floor the truck takes off but i hit the rev limiter and the trans wont shift out of first gear till i back off the throttle.  It shifts great when I take off normal and if I mash it in any other gear its fine.  I've had the bands and clutch packs replaced and they are adjusted properly.  The pressure is turned up to 65 psi on the valve body.  The TV cable has been set correctly.  Is it possible I need to replace the solenoids inside the trans?

 

The engine is pretty much stock except for my Quadzilla.

65psi at what point.....

 

And the tv lever is too tight. Why when you back off the throttle it will shift.

[martinique78]

It's 65 psi at idle in neutral.

 

So you're saying i need to let some slack in the TV?

[jlbayes]

Just a bit. It should not take much.

Ok, i'll give it a try this afternoon and see what it does.  Thanks!

Set the TV cable so that your WOT 1-2 shift occurs at 2900 rpm. It sounds like it's quite a bit too tight right now.
