I did the mod about 2 months ago, and just this past weekend the tranny developed a buzzing sound in park and neutral.
Also the shifts have become less firm {she won't scratch 2nd}.

Would this be caused by the EPC solenoid?
And if so should I just replace it with the stock one?
Do I need to drop the valve-body again to replace it?

Please help:bowdown: if you can.

Thanks, Fuel man~~~

I changed my EPC solenoid when I did the mod in May. Still buzzes in park and neutral. But it did it before then so I don't sweat it.

That buzz...

Usually comes from the valves in the main control hammering against the casting. The cause of this is either too much line pressure or just a bad main control. The '94-'95's did this alot. I say live with it, if you can. Or try swapping a '96-'99 main control out of bone yard 4R70W CAR transmission.

But would this cause the shifts to soften up?
