Re: helppp removed shift shaft screw
Usually NO! Like thelmuth said it needs to come apart and re-assembled.
Be very careful when taking apart.
The cover of the shift shaft can be warped if you pry on it.
Remove all the screws and try to pry it at the waterpump base.
If you pry at the ends ican bend and it won't seaal right.
Also,you need to replace the o-ring and pressure test it.
