Manual Transmission/Transaxle: Description and Operation

DESCRIPTION





This five speed is a constant-mesh manual transaxle. All gear ranges, except reverse, are synchronized. The reverse gear utilizes a reverse brake for shifting ease. The reverse idler gear is supported on a sliding spindle idler shaft. The transaxle case is aluminum with a steel end-plate bearing cover. It is housed in a die-cast aluminum case featuring a two-piece, middle split design.

The T350 transaxle internal components can be serviced only by separating the gear case from the bellhousing case.

CAUTION: The transaxle output shaft is serviced as a unit. No disassembly and reassembly is possible. Damage to the transaxle may result.

TRANSAXLE IDENTIFICATION





The transaxle model, assembly number, and build date are on a metal I.D. tag (1) that is attached to the end cover of the transaxle.




This information is also shown on a bar code label (1) that is attached to the front of the transaxle.

NOTE: Transaxles use various final drive gear ratios in different vehicle applications. Therefore, it is necessary that the correct transaxle assembly number is used when ordering service parts.

GEAR RATIOS





CAUTION: All gears and shafts must not be interchanged with other transaxles; they will not function 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 differential assembly, thereby turning the drive axle shafts.

The gear ratios of each transaxle are shown in the following chart. The chart also shows which transaxles 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. 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, 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 seals and synchronizers.

SEALANTS

The sealant used to seal the transaxle case halves and input bearing is Mopar(R) Gasket Maker, Loctite(R) 518, or equivalent. The sealant used for the bearing end plate cover is Mopar(R) RTV.
