Hello,
As I reassemble my 4T65EV/GT, I have a nagging doubt about the Sonnax TCC apply valve I fitted.
Sizing the teflon seal was fine using the instructions but when I fitted it, it seems a tight fit and it doesn't move freely in the valve body against the spring. Is this normal? The original didn't seem to be particularly worn and I'm tempted to put that back in as it moves without issue in the body.
Hoping someone can help - trying to get the transmission back together and in the car this side of Christmas :-)
