Transmission Fluid Level, Check (AF 13-II/AF 17/AF

Note: A check of the
colour and smell of the automatic transmission fluid provides
initial diagnostic data on the condition of the mechanical
components of the automatic transmission.
Inspect
- Vehicle positioned horizontally.
- Parking brake applied.
- Brake pedal applied.
- Engine runs warm at idle speed.
- Switch selector level once through all positions from P to 1
and then back again to P.

- Drain small quantities of transmission fluid and fill into
glass.
Check colour and smell of drained transmission fluid:
- For red, clear transmission fluid without particles, continue
trouble-shooting according to Astra-G Checking Procedure "AF

- For brownish-black, cloudy and burnt smelling transmission
fluid it is recommended that the transmission be disassembled in
order to check and, if necessary, replace the lining plates of the
respective clutches (C) or brakes (B).
- If there is a high percentage of metal particles in the
transmission fluid then it is recommended that the transmission be
replaced with one that has been overhauled.
