My Edge use to stall 2200 @0 boost, now its 1200.
And at wide open at the line @ 5 psi 2800 rpm now it’s just 1500 @ 5 psi.
Is it down on power or is something broken in the transmission or converter?
What’s your line pressure? I’m betting your TV cable is adjusted wrong or completely broken. If you drive with low line pressure for to long you will be rebuilding a trans aswell .
