Without a manual, you are essentially blind. Guessing the stack height on a clutch pack or mixing up the 12 different sealing rings leads to immediate pressure loss and a burned transmission.
To isolate mechanical wear from hydraulic leakage, install pressure gauges on the diagnostic ports located on the control valve housing: Solenoid valve open circuit or short to ground
Extract the input, output, and pump shafts. Disassemble the specific clutch packs (KV, KR, K1, K2, K3, K4). 4. Critical Assembly Rules
: This determines if the torque converter is failing or if the engine isn't providing enough input. Phase 2: The Tear-Down
: The main transmission holds approximately 26 liters, though this can vary by specific model and application. Standard Maintenance Procedures
