I am getting a bit of lag between P & D and if needed I would like to replace the B4 servo. If it has been replaced I may need more flushing (went through some flushing over a period of time -- 5 quarts Mobil 3309).

I think there is a way to tell if the B4 is the original or has been replaced.

 

The B4 servo has nothing to do with P-D, so it isn't your problem.

 

Thanks

I thought I've read that it helps solve the lag from P to D. Oops just looked at the B4 is flare from 2 to 3. On my car I have to watch when I go from park to drive and can't give it gas too quickly. It would be harsh on the trans if I did.
