Governor.

Let me start out by saying.....Stock V8 700R4 Governors are calibrated to hit "High Gear" as soon as possible for MPG & Emissions reasons, Corvette & F-body Light Weight Governors being the exception.
But they have there drawbacks as well like "Floating the Valves" on a WOT 1-2 shift on certain engines.

I have found that using TH350 Governors are a good compromise, New NOS ones can be found on E-Bay.

TCI & B&M sell Governor Calibration kits, If you wish to go that route.

**Tuning with TransGo Governor Springs**
These are Combinations I find to work well.

Earliest Shift to Latest Shift....

Red & Yellow
Blue & Yellow
Red & Green
Red & Black
Blue & Green
Red & White
Blue & Black
Blue & White
Yellow & Green
Yellow & Black
Yellow & White
Green & White
Yellow & No Spring

The Green Governor spring comes in TH350 shift kits, It is modeled after a Stock Green TH350 spring.

Inspect Governor Gear for wear.

Make sure the Governor Valve has free movement, Hold the Weights closed & shake the Governor, The Valve movement should be audible.

Insert Governor in it's bore.

Install the square cut Cover seal on the Governor Cover.

Install Governor Cover, Do Not Use Silicone, That seems to be a thing for people to do....It's not needed.
