I am going to have a go at a trans service on our 2010 2.4 GV. It has done 110000km and isn't reversing very well when cold and is shifting a bit harsh.

I have a aftermarket trans service kit and a stack of fluid, is there anything I should be aware of when doing the service?
The last auto I serviced was a Holden trimatic which was about 25 years ago so I have no idea what I am doing.

Also what is the correct procedure for checking fluid level? We never got a owners manual with the car.

This is from a shop manual for an early 2.0 NGV. Doesn't say anything about servicing the AT, just stuff on fluid level and fluid change, a whole lot of stuff on using the diagnostic scan tool and disassembly/reassembly.


A/T Fluid Level Check

At Normal Operating Temperature

1)Drive vehicle so that A/T fluid temperature reach the
normal operating temperature (70 – 80 °C (158 –
176 °F)).

2)Stop vehicle with engine running and place it level.

3)With select lever at “P” range, apply parking brake
and place chocks against wheels.

4)Keep engine idling and shift selector slowly to “L”
and back to “P” range.

5)With engine idling, pull out dipstick (1), wipe it off
with a clean cloth and put it back into place.

6)Pull out dipstick (1) again and check fluid level
indicated on it. Fluid level should be between FULL
HOT and LOW HOT. If it is below LOW HOT, add
specified A/T fluid up to FULL HOT.



NOTE
• DO NOT RACE ENGINE while checking
fluid level, even after engine is started.
• DO NOT OVERFILL. Overfilling can causes
foaming and loss of fluid through breather.
Then slippage and transmission failure can
result.
• If vehicle was driven under high load such
as pulling a trailer, fluid level should be
checked about half an hour after it is
stopped.
• When checking oil level, oil level gauge
must be used in proper direction. Insert oil
level gauge so that its front or back face is
directed to the front of vehicle. When oil
level indicated on front face of oil level
gauge differs from that on back face, use
lower one.


At Room Temperature
The fluid level check at room temperature performed
after repair or fluid change before test driving is just
preparation for level check of normal operating
temperature. The checking procedure itself is the same
as that described in “At Normal Operating Temperature”
under “A/T Fluid Level Check”. If the fluid level is
between FULL COLD and LOW COLD, proceed to test
drive. And when the fluid temperature has reached the
normal operating temperature, check fluid level again
and adjust it as necessary.

What oil do you have Shep? Just make sure it's the right stuff. Dexron III is a bit of an oil of the past now. Does it have a dipstick?

[shep]

Yes, has a Dipstick and using penrite ATF MHP semi synthetic trans fluid.

Good choice!
