Not best, but optimum Transmission?

Lefty. Sorry about the kookiness.

I check it after I've been out driving it. I come back to my driveway, coast to the bottom in Neutral, stop on the flat part of my driveway, then I let off the service brakes just to make sure it's in the flattest possible spot, when it doesn't roll even an inch I pull the park brake, leave it idling in Neutral and get out and pull the dipstick. Wipe it, put it back in, and pull it again and read it.

I drove it over the weekend. It was awesome. The slight knocking sound is only happening in park. And as of late, it seems like when I put it in park, sometimes it doesn't fully engage the parking pawl (and subsequently the starter won't turn, how I first started figuring that out). In those cases, I just shift to Neutral, and it fires right up.

Now I am more diligent to push the lever completely up in park and notice if I feel the weight of the vehicle gently rest on the pawl. If I'm on any slope, I pull the park brake before I let the weight rest on the parking pawl.

When I first had the headers installed it wouldn't go into L1. They guy who did the work is TOP NOTCH. I figured he had to jimmy the shift linkage to fit the headers and he said yes. I took it back and he adjusted again, and it shifted to L1 just fine. But I wonder if that last adjustment has made it not want to fully move into Park … but that was some time ago (more than a year).
