Throttle Pressure Adjustment
Insert Gauge Tool C-3763 between the throttle le­
ver cam and the kickdown valve stem (Fig. 102).
Push the gauge tool inward to compress the kick-
down valve against the spring and bottom the throt­
tle valve.
Maintain pressure against kickdown valve spring.
Turn throttle lever stop screw until the screw head
touches throttle lever tang and the throttle lever cam
touches gauge tool.

TRANSMISSION ASSEMBLY AND ADJUSTMENT
ASSEMBLY TIPS
Do not allow dirt, grease, or foreign material to en­
ter the case or transmission components during as­
sembly.
Keep the transmission case and components clean.
Also make sure the tools and workbench area used
for reassembly operations are equally clean.
Shop towels used for wiping off tools and your
hands must be made from lint free materials. Lint
will adhere to transmission parts and could interfere
with valve operation or even restrict fluid passages.
Lubricate transmission clutch and gear components
with Mopar ATF Plus, type 7176 transmission fluid
during reassembly. This is the preferred fluid for use
in 36RH/37RH transmissions. Use Mopar Dexron II
only when ATF Plus is not readily available.
Use Ru-Glyde, or Door-Eze, or petroleum jelly on
seals and O-rings to ease installation. Petroleum
jelly can also be used to hold thrust washers and
plates in position during assembly operations. How­
ever, d o n o t use chassis grease, bearing grease,
white grease, or similar lubricants on any part.
These types of lubricants can eventually block or re­
strict fluid passages and valve operation.
Do not force parts into place. Most of the transmis­
sion components/sub-assemblies are easily installed
by hand. If a part seems difficult to install, it is ei­
ther misaligned or incorrectly assembled. Verify t h a t
thrust washers, thrust plates and seal rings are cor­
rectly positioned. These parts will prevent proper as­
sembly is mispositioned (or "left out" by accident.
The planetary geartrain, front/rear clutch assem­
blies and oil pump are all much easier to install
when the transmission case is upright or as close to
this position as possible. Either tilt the case upward
with wood blocks, or cut a hole in the bench large
enough for the output shaft and rear support. Then
lower the shaft and support into the hole and support
the rear of the case directly on the bench.
Assembly Procedure
(1) Lubricate rear servo piston seal with petroleum
jelly, Ru-Glyde, or Door Eze. Lubricate servo bore in
case with transmission fluid.
(2) Install rear servo piston in case. Position piston
at slight angle to bore and insert piston with twist­
ing motion (Fig. 103).
