ZF & GM automatic transmission experts. Diagnostic-driven repair backed by real data — not guesswork.
Every repair starts with data. We scan, analyse, diagnose — then repair only what needs fixing.
Full drain and fill with OEM-specification fluid. We use the correct ATF for your exact gearbox — Lifeguard 6 for ZF 6HP, Lifeguard 8 for 8HP. Filter replacement included.
Gearboxes: ZF 6HP19, 6HP26, 8HP45, 8HP50, GM 6L45

Valve body service, solenoid replacement, and sleeve repair for the ZF mechatronic unit. We diagnose using real-time shift pressure analysis — not trial and error.
Common Symptoms: Harsh shifts, delayed engagement, limp mode (P0700, P0730)
From RM 2,000
Full strip, inspect and rebuild. Lockup clutch replacement, new bearing, re-balanced. We verify repair with live slip % measurement — must be <5% at cruise (per TRANS_T6 threshold).
Common Symptoms: Shudder at 60-80 km/h, RPM flare, P0741
From RM 2,500
Complete strip-down, inspection of every clutch pack, shaft, and bearing. New seals and gaskets. Rebuilt to OEM specification. Includes road test with diagnostic verification.
For severe cases: Multiple DTCs, metal in ATF, total loss of gears
From RM 6,000
Before any gearbox work, we run a full 7-system scan covering 53 rules. For transmissions specifically, we check 8 rules (TRANS_T1 through T8) — ATF temperature, shift times, torque converter slip, and gear ratio accuracy.
Gearboxes in Malaysia work harder than anywhere in Europe. Stop-start traffic means ATF temperatures regularly exceed 100°C. BMW's "lifetime fill" ATF degrades 2–3× faster. We recommend ATF service every 60,000 km.
We measure: ATF temp 60–90°C at idle, shift completion <300ms, torque converter slip <5% when locked, gear ratio accuracy ±0.5%. You only pay for what needs fixing.
We specialise in every BMW automatic gearbox variant found in Malaysia.
