GEARSHIFT PATTERN
The T350 transaxle shift pattern is a modified
H–pattern (Fig. 4). Overdrive fifth and reverse gears
are in–line and outboard of the first through fourth
gear positions.

LUBRICANT/ADDITIVES
T350 transaxles use Mopar ATF+4. Hy p o id g e a r
lu be o r e n g in e o il s h o u ld n o t be u s e d in th is
tra n s a x le . Hard shifting effort, bearing, gear, and/or
synchronizer failure may occur if incorrect fluid is
used.
The addition of any fluids to the transaxle, other
than the fluid listed above, is not recommended. An
exception to this policy is the use of special dyes to
aid in detecting fluid leaks. The use of transmission
sealers should be avoided, since they may adversely
affect synchronizers and seals.
SEALANTS
The sealant used to seal the transaxle case halves
and input bearing is Mopar Gasket Maker, Loctite
518, or equivalent. The sealant used for the bearing
end plate cover is Mopar RTV.

HARD SHIFTING
YES
crossover cable. If hard shifting is accompanied by
gear clash, synchronizer clutch and stop rings or gear
teeth may be worn or damaged.
shifting problems. Incorrectly installed synchronizer
sleeves, struts, or springs can cause shift problems.
lic system/components can also cause difficult shift-
ing or gear clash.
NOISY OPERATION
damaged components. Chipped, broken gear or syn-
chronizer teeth, and brinnelled, spalled bearings all
cause noise.
nents is frequently the end result of insufficient
lubricant.
SLIPS OUT OF GEAR
aligned or damaged shift components, or worn teeth
on the drive gears or synchronizer components. Incor-
rect assembly also causes gear disengagement.
LOW LUBRICANT LEVEL
result of leaks, or inaccurate fluid level check or refill
method. Ve h ic le m u s t be le v e l to a c c u ra te ly
c h e c k flu id le v e l. Leakage is evident by the pres-
ence of oil around the leak point. If leakage is not
evident, the condition is probably the result of an
underfill.
a transaxle, be sure the equipment is properly cali-
brated. Equipment out of calibration can lead to an
underfill condition.
CLUTCH PROBLEMS
can cause difficult shifting, gear clash, and noise.
release bearing can cause hard shifting and gear
clash.
