Line Pressure Tap is located in the converter
housing on the right hand side as shown below.
Normal line pressure should be 50-53 PSI, when
in Park or Neutral and RPM below 1500, and
then should rise smoothly with throttle opening
when in gear and road testing. Amount of line
rise will depend on engine load and vehicle speed.

Perform this procedure for vehicles that are not
equipped with a fill tube and dipstick.
1. Unlock the fill tube plug by lifting up on the
plunger. Once the plunger is lifted, remove
the entire plug assembly, as shown above.
Note: You may want to purchase an extra
dipstick tube to assist in filling this unit.
2. Fill unit only with the appropriate amount of
Dexron VI® fluid needed to fill the unit based
on the type of repair performed. See capacity
chart below.
3. Since the Corvette unit is not equipped with a
fill tube and dipstick, a tube in the bottom pan
is used to set the fluid level, much like some
Ford transmissions.
4. Raise the vehicle on a hoist. The vehicle must
be level, with the engine running and the shift
lever in the PARK position. Allow the engine
to idle for at least a minute.
5. The engine must be running when the fluid
level control plug in bottom pan is removed
or excessive fluid loss will occur, resulting in
an under-filled condition.
6. If the fluid is flowing as a steady stream, wait
until the fluid begins to drip.
7. If no fluid comes out, add fluid until the fluid
drips out and reinstall fluid level control plug
in bottom pan.
