Technical issues and repair guidelines

Like in all RWD automatic transmissions of Jatco, the design of RE7R01A elements implies a very long resource for this gearbox under the condition of preventing operation with contaminated fluid, which leads to the chain reaction: contaminated oil results in worn-out teflon rings, clogged valve body, worn-out solenoids leading to oil starvation of frictions.


It is common to replace torque converter spare parts in the course of overhaul of this transmission. Traditionally, the JR710 reassembly includes the repair kit of gaskets and seals. All rings, gaskets, and seals get replaced. The brake pack В3 (2-3-4-6) is the first to sense reduced oil pressure. Frictions with steel discs get burnt. The pack of С1 (Input) frictions is the second to get burnt. In this case, it is required to replace the whole set of frictions. Regular cleaning of the valve body and repair of the torque converter are performed together with replacement of the hydraulic clutch frictions. Problems in the RE7R01 electrical part are related to the valve body and the control unit.
