Information about Condition of Automatic Transmission Fluid

 

A check of the condition (colour and odour) of the transmission fluid can supply initial diagnosis information about the transmission. This information must be used for the elimination of conditions which, if not recognised early enough, would lead to extensive transmission repairs.

If possible, this check should not be performed after a test drive, as there would then be a risk of burning.

The automatic transmission fluid can always be checked by opening the check bolt on the transmission fluid pan. When closing the check aperture with the check bolt, always use a new seal.

 

 

To top up or change the transmission fluid, use only "DEXRON ® III...". For further information, consult the brochures "Opel/Vauxhall Inspection System" or the "Service Instructions Omega-B, group K".

 

 

Note:

 

Overfilling the automatic transmission leads to foaming, loss of fluid or fluid escaping from the vent hose. This can lead to shifting problems and possibly damage the transmission.

 

 

IMPORTANT:

 

New automatic transmission fluid is red to distinguish it as automatic transmission fluid from engine oil and anti-freeze. The red colour is not an indication of quality and does not remain permanently; in operation the colour changes to light brown.

 

 

Dark brown transmission fluid with a burned odour can indicate excessive contamination. The cause of this may however be severe defects in the transmission (e.g. burned clutch linings).

Checking Colour of Transmission Fluid

 

01

·   Determine fluid condition according to colour of automatic

Red, transparent

 

     transmission fluid (degree of contamination)

No particles visible in fluid

 

 

 

 

 

Note:

 

 

 

 

 

Normal condition = red, no particles visible in fluid

High wear/long-term use = light brown to brown, no particles visible in fluid

Contaminated condition = opaque or dark brown, particles contained in fluid

 

 

 

 

 

 

Yes:   E 01

No:      E 02, E 03

 

 

Nr.

Result

E 01

Fluid condition is normal, no contamination

 

Transmission fluid change not required

 

 

 

 

Further measures:

 

 

 

Carry out fluid level check

 

 

 

 

1.  Fluid level too low

 

·   Top up automatic transmission fluid

 

·   Check for leaks

 

·   Eliminate leaks (see Service Instructions)

 

 

 

 

2.  Fluid level too high

 

·   Drain /correct automatic transmission fluid

 

 

E 02

Remove transmission fluid pan

 

·   Minor contamination and deposits on bottom of fluid pan

 

     Transmission fluid change required (see Service Instructions)

 

 

 

 

Further measures:

 

 

 

A transmission overhaul may be necessary to replace damaged clutch linings and defective gaskets/seal rings

 

 

 

 

·   Change transmission fluid filter

 

·   Clean/rinse automatic transmission fluid cooler and lines

 

·   Top up automatic transmission fluid

 

·   Check/correct fluid level

 

·   Clean/replace dirty solenoid valves

 

·   Remove metal remains or other deposits from fluid pan

 

 

E 03

Contamination by engine coolant

 

 

 

 

Further measures:

 

 

 

·   Replace radiator

 

·   Transmission overhaul required

 

·   Clean automatic transmission fluid cooler and lines

 

·   Top up automatic transmission fluid

 

·   Check/correct fluid level

 

 

 

 

Suspected cause of fault:

 

 

 

·   Damaged clutch linings and seal rings

 

·   Dirty solenoid valves

 

 

 

 

Note:

 

The instruction "see Service Instructions" in this table refers to the "Service Instructions Omega-B, group K".
