So as part of diagnosing my shifting problem (sometimes starts in 2nd, sometimes won't shift out of 1st) I pulled the governor to see whether the valve is working.

At first I thought it was stuck pushed in, in the "high RPM" position. When the weights are collapsed, the valve stays pushed it & doesn't move. However I can use a popcicle stick pull it out towards the bottom of the governor, it seems to move freely.

I was thinking it would be sprung against the tension of the weights, but this isn't the case. When in the transmission, does fluid pressure keep the valve against the weights? I just want to make sure I'm not missing a spring or that's somethings not working.

Just some basic info, does not answer your valve

Thanks, I think I figured it out.
I found a youtube by monstertransmission that shows a governor, it looks like the valve isn't sprung but it should slide up & down from gravity as you turn the governor upside down.

Mine wouldn't do that before, but after soaking the non-gear end in gumout solvent & shooting up the bore with choke clearner, the valve slides up & down nice & smooth with no apparent hang-ups. It now behaves just like the one on the video. The gear itself looks fine so I'm going to re-install.

I'm hoping this is at least part of my shifting problem, I'm also going to drop the pan & make sure the small governor filter screens are in place, now I'm starting to think they may have fallen out when I did my shift kit a few years ago.

Hope you will be fine My governor was sticking. Cleaned it. Lasted 15 is miles. Took it out, cleaned again. Lasted 30 miles. My trans had to be rebuilt.

I fixed my governor by taking it apart and sanding off the sharp edges on the piston. While in Drive it would stay stuck in 1st at red line and wouldn't shift into 2nd unless I lifted. All good now.
