shifting issue
Good morning, been a minute since I posted last. after almost 20- years the highboy got the highboy back on the road a few months ago and its running great. question about shifting.
1. I need to let off the accellerator slightly before it will shift gears, and depending how fast I'm going it hits a bit hard. Don't know if it has a shift kit or not. Modulator??? I did service the trans and it was very clean.
2. If I shift it manually it shifts smooth.
3. It goes into park but I need to make absolutely certain its in park and I ALWAYS makes certain the parking brake is on. it slipped out of park one time. is there an adjustment for this? worn parts?
Thanks

Thnx I should have mentioned it. I don't have the kickdown hooked up right now, I put on and edlebrock but I don't think a kick down will make a difference with the normal driving, it will shift I just have to let off the accelerator a little to allpw it to happen.

If it has a Modulator pull the vacuum hose off it at the Modulator and see if there is any ATF there.
If so change it out. I think there is a colored band on it you will need to get the same color one.
Also watch when you pull it as there is a metal pin that may fall out and needs to be reused with the new valve.
Are you sure the ATF level is right?
From sitting the valves in the valve body could be gummed up and seals dried up. May get better with miles?

Thnx, I’m going to pull the modulator. The level is good, I cruised slow a couple miles at a time knowing the clutches would be dry.
then I serviced it with new fluid n filter which was very clean. Going to change cooler lines n inline filter as well.
