This Guide Will Help in Changing the Fluid and Filter on Vehicles VN - VS with TH700 Automatic Trans
1. Purchase Gearbox Service Kit From Holden - Amcap - Repco - Coventrys etc
Gearbox Service kit is GM Part Number 8657926
This Should Contain
1x Automatic Transmission Filter
2x Transmission Oil Pan Gaskets
2. You should have a Good Working Area I chose to park the car in the driveway but anything open and safe is ok Jack the Car up and place stands in appropriate locations
3. Slide under the car and take a look underneith the Automatic Transmission Where u will be greeted by a series of 13mm Bolts undo them and have them sit to the side its also a good idea to have a drain tray to collect any fluid that may come out and let the vehicle cool if it had been recently driven ( i found out the hard way)
4. Pull Trans Sump off if it has fallen off already and place to the side
5. Pull Trans Filter Downwards and out then into the closest preferable Bin
6. Push new Transfilter into Filter Bore (where u just pulled the old one out from)
7. Clean the Pan and the surface where it connects to (Remove the old gasket)
8. There are two Gaskets in the Kit and one is made from Paper and the other Cork the Paper one is used for trans pans that have a continous raised line on the mounting surface and the cork one is used on the trans pan that has a non continuous raised line around the mounting surface (Mine was a Series 1 VN which uses the Paper one )
9. place new gasket onto pan and bolt the 13 mm bolts back in and tighten to 11nm if u have a torque wrench if not u decide when u think its tight enough.
10. Lower Car back down onto Ground and fill Transmission Filler through the dipstick hole with 4.8 Lts Approximately.
11. Completed Fluid and Filter Change have fun
Ok, after doing this job last weekend on my VS series II, I will never do it again! It was a really dirty job!
If you want to get your hair drenched in transmission fluid, go right ahead. This stuff stinks when it comes out of your gearbox, too.
Tips for newbies... USE A TARP! It's a messy job. You don't have much space under your car when its on ramps and chassis stands. When you remove the bolts around the sides and the front of the pan, expect it to be UNCOMFORTABLE while you're trying to hold up the pan with one hand while you're undoing those last few bolts at the back of the pan. It weighs a lot when you're on your back, and you've got a large container between the ground and the gearbox. You don't have much room for your arm!
Next, when you start trying to get the seal out, don't expect it to come out easily. With the drain tray just behind your head, you're trying to pull this seal out... which does NOT want to come out! It's in damn tight. But once you butcher the rubber, you have no choice but to get the thing out. So, after trying with circlip pliers for a good hour, the only way you're gonna get the thing out is with a small screwdriver and hammer, to bend the thing out of shape and then remove it.
By this time, you're hair has been sitting in the drain pan, your torch is covered with dripping transmission fluid, and you're cursed almost every swear word known to man.
Cleaning the pan and removing the old gasket remnants is like a walk in the park after you've got that bloody seal out!
The new seal taps in pretty easily with a hammer, and the pan and gasket goes on without too much more trouble. Torquing up the bolts to the required 11nm is pretty simple after you've done all the previous chores. Of course, the tarp is covered with fluid and is only worth throwing away at the end of the job.
If you like being dirty, and working in very uncomfortable areas, go for it. Personally, i'm just glad its done and back together.
Still want to service your own tranny? THINK TWICE!!!!
My other car, the VT? I'm taking that to the transmission specialists to get them to do it.... never again!
Are there any bands that need adjusting in this service? i know some auto's require it.
Pfft, getting dirty is half the fun.
Try changing said gearbox in an L300 van when you gotta drop the motor 50mm to slide the gearbox off. same oil, just a lot heavier thing to put in place.
A tip is to take out all the bolts across the rear of the pan and about half way up each side, loosen the rest, this will tip the pan backwards and let it drain most of the fluid out before you remove the rest of the bolts. It is still messy, but a lot easier than trying to balance a full pan.
another tip is to ensure the draining container you are using is wide enough to catch the fluid without it missing it all together :P (Made that mistake only once)
One further tip (THIS IS SO BUSHMAN STYLE YOU PROBABLY SHOULDNT DO IT) is to remove the return hose from the trans line and place it into an empty 2 litre coke bottle and drain some out by starting the engine before you start the undoing and tipping stage with the pan.
Sorry I had to throw in that it is bushman and could harm your tranny
honestly, what i would do if i had an auto, would be to either
a: Clean your sump up real good, then weld a drain plug in there somewhere where it wouldnt get damaged easily.
b: get a length of wood, place 2 jacks either side and use it to hold pan in place while you remove the bolts. Then, lower each jack just enough to be able to remove the pan upright or even just tip it into a container with two hands.
Undo the bolts while holding the pan against the trans, the let go really quick.....
