If you own a Falcon manufactured after Febuary 1996 chances are you have gone looking for the transmission dipstick and come up blank, and for good reason, they don’t have one! Falcons made after this date have a ’sealed’ transmission and have no dipstick, only a filler plug on the side of the transmission similar to what you would find on a manual gearbox.
This does make checking the fluid level and condition a bit more involved however with a trolley jack, two sets of chassis stands and a good quality 16mm ring spanner or socket and ratchet it can be done without too much drama. The reason I say to use good quality tools is because the plug in the transmission is usually very tight and sooo easy to round off and the only way you can be sure that this won’t happen to you is if you use quality tools.
This check should be done when the transmission fluid is cold.
The first thing to do is to jack the car up front and rear and try to get it as level as possible. It is important to use chassis stands as you will be getting underneath the car and this should not be done when the car is supported by the jack alone if you want to celebrate your next birthday!
Once you have the car level and secure, slide underneath the drivers side about in line with the front of the drivers door. This is what you are looking for; (please note in this pic the exhaust is removed as this transmission was coming out but it will give you the general idea).

The little red arrow points to the location of the plug. This particular plug was so rounded off that we had to drop the transmission down as much as possible and weld a nut to it. Shame really as the transmission was coming out but I wanted the pictures to look right!

Now with your 16mm spanner or socket fitted as squarely as possible on the plug heave on it in a anti-clockwise direction. All going well it should undo and screw all the way out with no problems. The plug has an ‘o’ ring on it to stop any fluid leaking.
When cold the transmission fluid should be level with this hole. The easiest way to get an idea of the fluids condition is to stick a clean finger in to the hole and have a look at the colour on your finger and also smell the fluid, checking for any ‘burnt’ or overheated smell.
NOTE: ‘Dexron’ type transmission fluid is not compatible with these transmissions. The correct ‘TQ95′ transmission fluid must be used.
If the fluid is not a clean red colour or if it smells like it has been hot I would advise getting a transmission service done as soon as possible. Also a good idea is to fit an aftermarket transmission cooler as the factory one is limited in it’s cooling capacity.
We have a great tutorial courtesy of Paul Taylor (Tinntter) for the fitment of two transmission coolers here. Paul fits two of them to further increase the cooling and has clocked up thousands of kay’s without a drama. Oh, and remember not to over-tighten the plug when your finished as you don’t want to have drama next time you do this job.

hi,
excellent article.Yes,TQ95 fluid should be used.
dont use a 16mm use a 5/8 it fits better.
I have just had the misfortune of purchasing my first falcon, an XH ute….after years of driving holden utes of all types and easily servicing and checking on things myself and having never had a mechanical drama I’ve gotten a falcon having heard over the years how much better they are for towing.
I tow once to find the the transmission starts playying up only to find myself under the bonnet feeling like an idiot for an hour cause I can’t find the trans dipstick…..another monumentally bad idea from the genius of ford engineering….I’M GOING BACK TO HOLDEN!!!!!!!
Hi-Make sure that you use a SINGLE HEX socket or ring spanner, and you will be very unlikely to round off the plug.
Cheers.
Absolutely Rod, good tip, thanks for that.
It’s a 5/8 bolt all right cause the 16mm just rounded the bolt head. how fucked is that 2009 and they still using imperial bolts the tight asses. fancy not even having a dip stick that’s just unbelievable.
and the pictures above seem to show alot more room and space around the bolt than what I have . Ford suck dogs nobs.
My 4th falcon a AU – had a tail shaft seal leak. Replaced seal, bought TQ95 fluid, 45 minutes later, goggling how to fill transmission on a AU. Thanks for the tips fellas. It is a weird set up. Now I will have to jack it up again. Leave it for another day.
No worries Wayne, sure is an odd setup. Hope you managed to get it sorted.
G’day mate I have a EL Falcon and the oil is leaking between the engine and the transmission, I know it is a costly job to replace the seals and would like to put some Nulon Stop Transmission Leak Oil to my transmission, I would like to know which hose I will have to remove from my radiator that cools the transmission oil as I want to drain out the oil from the Torque Converter too when changing the transmission oil, can you guide me in this. Also if I am going to fit an aftermarket oil cooler, how to fix it and also how to block off the hole in the radiator.
Thanks & Regards,
Liston Spink
Liston….Go buy 44 galls of fluid on rotate it….OR drop your sump on the box and drain…either way it messy and you ain’t gonna save it..if thats what your after……After market cooler? why do you want to block of inlet or outlet????
