Here's a summary of the automatic transformer's failure diagnostic maintenance, which will be useful for you
Take, for example, the 3-adak automatic transmission
We can't change gear
Symptoms of failure
After stepping down the brake pedal, it was not possible to remove the shift pole from the p slot。
Possible cause of malfunction
The switch lock system is down
Moderate transmission failure maintenance methods
Check the locking system
Symptoms of failure
The ignition switch cannot be transferred from acc(i) to lonk(0). (key push, shift pole in p)
Possible cause of malfunction
Key chain failure
Methods of trouble maintenance
Check the lock system. Key lock system circuits
There's no reaction failure on the attached transmission
Symptoms of failure
Engines are running, but vehicles are not moving at all stages。
Possible cause of malfunction
1. Low level of atf oil 2. Resume wiring broken or irreconcilable
3. Retrenchment and transmission or car
4. Atf pump wears or binds
Atf filter plugging
8. Main brake gear grinding or damage
Methods of trouble maintenance
• check the atf oil table and check whether the atf cooler pipe leaks and the connection is loose. If necessary, wash the atf cooler pipe. • check that the retrofit poles and gear transformers are loose。
• the atf pump and the rectangular shell are not properly positioned, causing the atf pump to bite. Symptoms are mostly ticking noises or rushing screams that occur at the turn. • measuring pipe pressure。
• when replacing the main bearing, be careful not to damage the rectangular shell. The removal of the main valve may also cause damage to the atf pump. If no testing is carried out, the atf pump may be bitten. Use the right tools。
When the main seal is installed, it is aligned with the rectangular shell. If the lower end of the rectangular shell is exposed after the thruster, the fluid circuit is blocked and damage is caused。
Check if the atf filter is blocked. If the filter is blocked by steel or aluminium crumbs, the atf pump is checked. If the atf pump is normal, the damaged components that produce shredding should be identified and the rectangles replaced. Yeah
Test if the gear is worn out. In the case of small gear grinding of differentials, the total number of differentials is replaced, the atf filter is replaced, the speed transformer is completely cleaned, and rectangulars, coolers and pipes are washed。
We're losing some gear
Symptoms of failure
Vehicles can travel at 2 and r points, but not at d, d3 or 1。
Possible cause of malfunction
1. 1-class pressurer failure 2. 1-class gear wear and tear 3. 1-class clutch failure
Methods of trouble maintenance
• check the pressure of the 1st platoon。
Check the clutch pistons and o-sealed. Check for wear and tear of the spring coils and coil seals. Detects the gap between the end plate and the top plate of the clutch. If the gap is beyond the scope of the discrepancy, the wear or damage of the discs and pieces of the plates shall be checked. If the disc is worn or damaged, the sets are replaced. Detects the height of the plate of the clutch. If the altitude is above the range of the scale, the tablet is replaced. If the height is normal, adjust the gap between the clutch terminal plate。
• detection of the 1st-class clutch pipeline. In the event of a scarring of the first-class clutch pipe, the o-sealed ring under the pipeline and the conduit is replaced。
• replacement of the second axis in the event of a loose or damaged liner for a first-stage clutch。
Symptoms of failure
Vehicles can travel at stages d, d3, 1 and r, but not at level 2。
Possible cause of malfunction
1. 2-class pressurizer failure 2. 2-class gear wear and tear 3. 2-class clutch failure
Methods of trouble maintenance
• check the pressure of the 2nd platoon。
• check the clutch pistons and the o-type seals. Check for wear and tear of the spring coils and coil seals. Detects the gap between the end plate and the top plate of the clutch. If the gap is beyond the scope of the discrepancy, check whether the discs and pieces are worn or damaged. If the disc is worn or damaged, the sets are replaced. Detects the height of the plate of the clutch, and replaces the plate if the height exceeds the range of the mass. If the height is normal, adjust the gap between the clutch terminal plate。
Symptoms of failure
Vehicles can travel at d, d3, 2 and 1, but not at r。
Possible cause of malfunction
Electromagnetic valve e failure
4. Battery of the 4th tranche/replaced pressurizer
6. Reclining gear wear and tear
Methods of trouble maintenance
• check the d light and check if the plug-in is loose. Check if the retro-magnetic valve e bites. Check if the o seal is worn or damaged。
• check for loss of forklift bolts on the forklift axis. • check the pressure of the 4-bed clutch。
• detection of the clutch piston, the clutch piston one-way valve and the o-type seal. Check the wear and tear of the spring coop. Checks the gap between the panel and the ceiling. If the gap is beyond the scope of the discrepancy, check if the discs and plates are worn out and damaged. If the discs are worn and damaged, they are replaced. Detects the height of the plate of the clutch, and replaces the plate if the height exceeds the range of the mass. If the height is normal, adjust the gap between the clutch terminal plate. Yeah
Test the rewinding of the gears on the side of the gears and test the rewinding of the gears on the side-axis 4 and reverse gears. If the rewinding gears and rewinds combine wear and tear, replace them. If the transformer has an acoustic, friction or call, the main axle-4 gear, the reverse inert wheel and the subaxy-4 gear are also replaced。

Car accelerator failure
Symptoms of failure
Poor accelerator performance; explosion at d, d3 and r positions; high rate of failure at 2 and 1 and d3 at 1 and 2
Possible cause of malfunction
1. Low atf oil table
2. The switch is broken or irreconcilable。
3. Atf oil pump wears or binds
5. Atf filter plugging。
Methods of trouble maintenance
Check the atf oil table and check if the atf cooler pipe leaks and the connection is loose. If necessary, wash the atf cooler pipe。
• check that the retrofit poles and gear transformers are loose。
The atf pumps and the rectangular casings are poorly positioned and cause the atf pumps to bite. Symptoms are mostly ticking noises or rushing screams from rotation。
Check if the atf filter is blocked. If the filter is blocked by steel or aluminium crumbs, the atf pump is checked. If the atf pump is normal, the damaged components that generate debris should be identified and the rectangulars replaced。

Methods of trouble maintenance
Zoom in
• check the clutch pistons and the o-type seals. Check for wear and tear of the spring coils and coil seals. Checks the gap between the panel and the ceiling. If the gap is beyond the scope of the discrepancy, check if the discs and plates are worn out and damaged. If the discs are worn and damaged, they are replaced. Detects the height of the plate of the clutch, and replaces the plate if the height exceeds the range of the mass. If the height is normal, adjust the gap between the clutch terminal plate。
