Ремонт АКПП Джили Монджаро на 25000 км часть 2

Video Navigation: 00:00 Start 00:05 Introduction • The transmission is an eight-speed automatic transmission from the Japanese company Aisin Warner. • The first part shows the diagnostics and the decision to disassemble the transmission. 00:48 Transmission Origin • The transmission is manufactured by the Chinese company Link Eco, not Aisin Warner. • The transmission design was developed by Japanese engineers. 02:00 Diagnostics and Problem Detection • Errors were detected with the C4 clutch and an incorrect gear ratio between fourth and sixth gears. • Checking the valve body and solenoids revealed no problems. • Pressure testing of the C3 and C4 clutches revealed a leak in the C4 clutch. 04:30 Transmission Disassembly • The transmission was removed and disassembled. • Two clutches and a brake band were found inside the drum. • A leak was detected under the C4 clutch piston. 07:32 Piston Damage Analysis • The C4 clutch piston seal is damaged. • The piston sealing edge is worn and damaged. 09:21 Causes of Damage • Poor drum finish where the seals operate. • Soft and thin piston sealing edge. • No markings on the piston. 14:36 ​​Conclusion and Repair Plan • The cause of the failure is poor workmanship from Link Eco. • Replacement of the rubber-coated piston set, seals, gaskets, and filter is planned. • Repair coordination with the vehicle owner. 17:05 Introduction to the Transmission • The eight-speed transmission is structurally similar to the six-speed TF-80/81. • The main differences are one more clutch pack and one more solenoid in the valve body. 18:01 Design Features • The Japanese increased the number of gears by adding one extra clutch and clutch pack. • The transmission housing is reminiscent of the TF-80. 18:56 Pump and Drum • The pump is similar to the TF-80 pump. • The C34 drum has two clutch packs instead of one. • The brake band is responsible for second and eighth gears. 19:51 Front Planetary Gearset • Double planetary gearset with ten planet gears. • One sun gear and one ring gear. 20:43 Rear Planetary Gearset • Structurally similar to a six-speed transmission. • Eight planet gears and two sun gears. 21:22 C1 Drum and Low Reverse Clutch • The C1 drum is responsible for first, second, third, fourth, and fifth gears. • Aluminum piston and seal. • The Low Reverse clutch controls reverse gear and first gear in manual mode. 22:12 C2 Drum and Central Gear • The C2 drum controls fifth, sixth, seventh, and eighth gears. • The central gear is combined with the ring gear. 24:10 Valve Body • The valve body from an eight-speed transmission has ten solenoids. • One solenoid is missing due to the reduced number of clutches. 25:07 Conclusion and Recommendations • When purchasing a Chinese car, be aware of potential transmission issues. • Chinese manufacturers have not yet gained sufficient experience in designing complex components. • Over time, the quality of Chinese components may improve.
