Well it's been a while since my last post.
Loving the 94 Montie everytime I get in it!

I have some ?'s regarding Auto Trans flush/service.
The fluid is looking brown now and I think it's time for a change.
I have noticed that when I first start the car in the morning,
select R to back it out of the driveway that the car doesn't
seem to move on its own accord as it used to. Takes a few seconds
before it will start to move by itself. (Is this norm as it's the first auto I
have owned).

So I figure it's time to change the fluid.
Holden want $140 for service & flush.
Sent them an email asking....
In regards to the automatic transmission service/flush for $140.
What exaclty is done in the service and do you drain all of the old fluid out with the flush?
Answer...
The transmission flush is designed to remove all the old oil including what is held in the torque converter.

So from what I understand it's just a flush...no service as such!!!

I want to do it myself and save some $.
From what I have seen and heard it's pretty straight forward.
Any tips on how to do it.
Do I need to get one of those cheap oil pump/drainers so I get all the fluid out?
Looks like it would make it alot easier to pump the old stuff out and the new in.
Or is there a special technique to flush the old oil thats in the torque converter
as Holden have suggested.

What auto trans fluid should I get? Dex III?

Savvas, howdy. I know you have the book on CD for the Jack. Any chance you could email me the section to show the steps on what to do? Let me know.

Or should I just book her in?

thanks heaps

Hi Savvas,

I have seen those Isuzu CDs on Ebay. Do they cover the 1997 2.6litre Rodeo (pickup)?

The list said they do the pickup but not the 1997 pickup?

I would be interested in buying one if I knew for sure that my model was covered.

Thanks.

Utemad ... The CD covers Isuzu Pickup upto the 1995 model. Includes the 2.6L engine though.

Thanks Savvas.

Would be worth it then as the mechanicals are almost identical for 95 and 97.

PS ... Just having a read through the process for the 94 model.

On your model you will need a torque wrench that reads in inch.lbs (or down to 4.5 Nm) to adjust the brake band.

The $140 from the dealer will also include a new strainer and gasket kit and (if they do flush everything) around 9L of Dexron II.

If you do the drain yourself you will only get about 5L out as the tools to do a flush are not your average home workshop thing.

By the way ... around 1994/95 the transmission changed to one without a dipstick. Does your Monty have a tranny dipstick?

I have the pdf's for both ready to go.

Gidday,Have a good sniff of the fluid to check if it has a burnt smell if so it might pay you to get it seviced properly.If it has a burnt smell it means that the discs or bands could be slipping.You may be paying $120.00 for something that could be fixed up with a service for a bit xtra.

I emailed holden asking if the strainer and gasket are replaced
in the $140 service/flush.
NO! Only replaces the oil, that’s it!!!
Why they call it a service/flush beats me, typical holden!

Dogart,

The person on the other end of the email is full of @#$% and has no idea.

They have to replace the gasket as the pan must be removed to drain the fluid. It cannot be possibly be replaced with the old gasket as it will leak like a seive. The strainer replacement (or at the very least a thorough cleaning) is also a standard part of any transmission service.

When my car had a transmission service earlier this year, it was close to $200 to do the full thing. That is fluid flushed and renewed, replace pan gasket and strainer, replacement drain screw and overflow screw. The latter 2 are for the non-dipstick transmission.

Savvas,
you don't have to remove the pan to flush a trans, in fact there are two methods commonly used in the trade to do this. One is a dedicated trans flushing machine which is fitted into the cooler lines of the trans of the vehicle which is then started and as the old oil is pumped out the new oil replaces it. The other method which most mechanics use is that they identify the cooler return line, disconnect it and start vehicle allowing oil to drain into a container, when the oil begins to splutter, turn off engine refill trans with new oil and repeat process until oil is clean.
regards
Scotty

Fair enough ... I didn't know that one.

I know they did remove mine because when I got there to pick it up, the pan was still off and they were doing the strainer.

here's a reply from a trans shop 'ere in Perth....

The price of $170.00 includes oil, filter, gasket and electrical check.
We do not flush the Transmission unless the customer would like it done
or the oil is discoloured.
Regular servicing should suffice.
If you decide to flush the Transmission the cost is $220.00.
We flush by removing the cooler line and running the motor.
Flushing with a machine can be detrimental as it forces foriegn material
into parts of the Transmission it should never reach, i.e. valve body.
The oil we use is Dextron 3.
