ok i replaced pwm tcc solenoid. now at wide open throttle first shift is fine in any gear but after it shifts the first time and tries to up shift its like i hit a wall. it wants to just sit at 4500 (still increase's speed not like it should though) but its like the stall is locked up. its a 4l60e with a shift kit and a edge 3600 converter with b&m synthetich trick shift. is it possible that the pwm tcc solenoid ruined the clutches in the stall. didnt have this problem before the pwm tcc solenoid went out.

 

The PWM solenoid would have no effect at all on a WOT run or shift into any gear, It only pertains to lockup and if you used for instance the transgo shift kit it does little if anything at all anyway ,
The Lockup clutch does not come on at WOT

 

What was the reason for replacing the PWM soleniod to begin with?

 

Good Question

 

i no it doesnt effect shifts at wide open throttle. im thinkn that the clutches are bad cause it acts like it locks up and just burns the clutches. i no i shouldnt have but i drove it for awhile with the solenoid bad.

 

the guy that did the shift kit for me broke the conector and forgot to tell me.

 

Actually with that solenoid bad you just would not have lockup so it would not burn the lockup clutch, And of not the converter does not lock at WOT either so would again have no affect .
Now there may be and issue with the kit install or even damage just coincidentally occurring , Whats the fluid condition and smell?

 

ok just making sure. well when i draind it to change the solenoid. it had a little metal in it not alot though. and i dont know if you have ever smelld b$m trick shift but it smell s like gear oil
