Diagnostics of malfunctions of manual transmission

Transmission and transfer case

Difficulties take place at gear shifting

Coupling is not squeezed up to the end out. See. The section devoted to diagnostics of malfunctions of coupling.

In a transmission transmission oil not that grade. Replace oil on corresponding to technical requirements (see size tables and adjustments at the end of the Management).

The gear shifting mechanism is worn-out. On models of 4.2 l dismantle the top cover and replace defective components. On models of 3.0 l disassemble transmission assembly for repair performance.

The synchronization mechanism is faulty. Execute major maintenance of transmission. Check a condition of frictional surfaces of blocking rings and cones on existence of signs of wear and damages (see an accompanying illustration).

1 — a synchronizer cone
2 — a blocking ring

At transfer fall transmission publishes a clang

Coupling is not squeezed up to the end out. See. The section devoted to diagnostics of malfunctions of coupling.

In a transmission transmission oil not that grade is filled in. Replace oil (see size tables and adjustments at the end of the Management).

The synchronization mechanism is faulty. Execute major maintenance of transmission. Check synchronizing teeth on gear wheels and blocking rings on existence of chips and wear signs (see an accompanying illustration).

1 — a gear wheel of the 2nd transfer
2 — a blocking ring
3 — a synchronizing teeth

It is excessive axial люфт gear wheels of a conducted shaft and/or an intermediate shaft of transmission. Disassemble assembly of transmission and replace defective components.

There are "soskakivany" transmissions from the chosen transfer

It is excessive люфт a control lever a transmission. Disassemble lever assembly with a casing and replace worn-out components.

The gear shifting mechanism is worn-out. On models of 4.2 l dismantle the top cover and replace defective components. On models of 3.0 l disassemble transmission assembly for repair performance.

The synchronization mechanism is faulty. Execute major maintenance of transmission.

It is excessive axial люфт gear wheels of a conducted shaft and/or an intermediate shaft of transmission. Disassemble assembly of transmission and replace defective components.

Bearings of primary or conducted shaft of a transmission are worn-out. Disassemble assembly of transmission and replace bearings.

In most cases such situation is caused by wear or damage of internal components of transmission.

Transmission publishes unusual noise in neutral situation

Level of transmission oil fell. Check transmission on existence of signs of leaks. Make necessary corrections, add necessary amount of oil of a demanded grade.

Bearings of primary shaft of a transmission are worn-out. Disassemble transmission and replace bearings.

If bearings are equipped with a separator and cannot be checked visually, carefully wash out them in solvent, slightly grease and slowly повращайте manually, checking on existence of breakthroughs and zakusyvaniye points (see an accompanying illustration).

Gear wheels of an intermediate shaft of transmission have defects in the form of chips or cavities, or shaft bearings are worn-out. Execute major maintenance of transmission, having replaced the damaged components.

It is excessive axial люфт an intermediate shaft of transmission. Disassemble transmission and replace defective components.

For identification of noise of transmission on a neutral squeeze out coupling at the working engine and include any transfer. If noise disappears, its source is transmission.

Transmission or transfer case publish noise (any of forward transfers is included, the car moves)

Level of transmission oil fell. Check transmission on existence of signs of leaks. Make necessary corrections, add necessary amount of oil of a demanded grade.

Oil traces in the basis of a drum of the parking brake indicate failure of an epiploon of a transfer case (see an accompanying illustration).

Bearings of transmission or transfer case are worn-out. Disassemble transmission / a transfer case, replace bearings.

Gear wheels have defects in the form of chips and cavities. Execute major maintenance of transmission / a transfer case, having replaced the damaged components.

It is excessive axial люфт an intermediate shaft of transmission or a transfer case. Disassemble transmission / a transfer case, replace defective components.

Switching of modes of a transfer case is complicated

Components of the switch of a transfer case are worn-out, or landing weakened them. Tighten fixture or replace faulty components.

Shlitsa of a nave and the coupling of switching raising/lowering transfers are worn-out. Execute major maintenance of a transfer case.

Shlitsa of gearing on a nave raising/lowering transfers or an entrance (primary) shaft are damaged or worn-out. Execute major maintenance of a transfer case.

Inclusion of an all-wheel drive mode is complicated

Components of the switch of a transfer case are worn-out, or landing weakened them. Tighten fixture or replace faulty components.

Components of the synchronizer of an all-wheel drive mode are worn-out. Execute major maintenance of a transfer case.

Teeth of an asterisk of the synchronizer of an all-wheel drive mode is worn-out or damaged.

Difficulties at inclusion of an all-wheel drive mode can appear also connected with distinction at a rate of tires of lobbies and back wheels of the car. Track correctness of selection of wheels.
If problems with switching on an all-wheel drive mode arise only in a cold condition, reduce speed up to a full stop.

Driveshafts

Driveshaft vibration takes place

Weakened nuts and/or bolts of fastening of the driveshaft. Replace fixture, having tightened it with demanded effort.

Kardanny hinges are worn-out. Check, in case of need make replacement.

Will bend the driveshaft. Check shaft palpation by means of a tsiferblatny measuring instrument of plunzherny type, compare result of measurement to admissible values (see size tables and adjustments at the end of the Management).

Driveshaft balancing is broken. Check existence on a shaft of balancing cargoes. In case of need execute shaft balancing.

There was a mutual rassovmeshcheniye of forward and back kardanny hinges of a shaft. Disconnect from a shaft a sliding joint and level hinges.

Shlitsa of a sliding joint of the driveshaft are worn-out. Replace a shaft assembled.

By means of manual manipulations check kardanny hinges and sliding joints on existence of signs of wear (see an accompanying illustration).
If excessive palpation of the driveshaft takes place, give fixture and turn a shaft on a half of turn. Again tighten fixture and repeat palpation check. In case of need replace a shaft.

Takes place excessive radial люфт the driveshaft

Weakened bolts/nuts of fastening of the driveshaft. Replace fixture, having tightened it with demanded effort. Surely track reliability of a tightening of fixture (see an accompanying illustration).

Kardanny hinges are worn-out. Check degree of wear of hinges, manipulating them manually. In case of need make replacement.

Shlitsa of a sliding joint of the driveshaft are worn-out. Check (by manual manipulations), in case of need replace a shaft assembled.

It is excessive radial люфт a koronchaty (conducted) gear wheel of the main transfer. Remove assembly of the main transfer, execute adjustment of a conducted gear wheel.
