So I swapped out my transmission fluid yesterday, replaced it with some pennzoil synchromesh because I had a small grind in third. I read on how to do it through the vehicle speed sensor (VSS). But now I'm having an issue with it going into gears. And it doesnt go into 5th. At all. And also do you fill it up to the top of the fill plug or the top of (VSS) Any help or suggestions., thank you.

 

fill plug on level ground

 

Sounds good thank you. And does it matter how you put the (vss) assembly in?
