GEAR RATIOS
CAUTION: All gears and shafts must not be inter-
changed with other transaxles; they will not func-
tion correctly.
The differential is a conventional arrangement of
gears that is supported by tapered roller bearings.
The final output gear turns the ring gear and differ-
ential assembly, thereby turning the drive axle
shafts.
The gear ratios of each transaxle are shown in the
following chart. The chart also shows which transax-
les are available with the reverse–input shaft brake.
This brake allows easier shifting into reverse and
helps eliminate reverse gear clash.

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
NOTE: All T350 Manual Transaxles require the use
of ATF+4 (Automatic Transmission Fluid).
Hypoid gear lube or engine oil should not be
used in this transaxle. Hard shifting effort, bear-
ing, 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 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.
DIAGNOSIS AND TESTING - COMMON
PROBLEM CAUSES
The majority of transaxle malfunctions are a result of:
• Insufficient lubrication
• Incorrect lubricant
• Misassembled or damaged internal components
• Improper operation
HARD SHIFTING
Hard shifting may be caused by a misadjusted
crossover cable. If hard shifting is accompanied by
gear clash, synchronizer clutch and stop rings or gear
teeth may be worn or damaged.
Misassembled synchronizer components also cause
shifting problems. Incorrectly installed synchronizer
sleeves, struts, or springs can cause shift problems.
Worn, damaged, missassembled or leaking hydrau-
lic system/components can also cause difficult shift-
ing or gear clash.
NOISY OPERATION
Transaxle noise is most often a result of worn or
damaged components. Chipped, broken gear or syn-
chronizer teeth, and brinnelled, spalled bearings all
cause noise.
Abnormal wear and damage to the internal compo-
nents is frequently the end result of insufficient
lubricant.
SLIPS OUT OF GEAR
Transaxle disengagement may be caused by mis-
aligned or damaged shift components, or worn teeth
on the drive gears or synchronizer components. Incor-
rect assembly also causes gear disengagement.
