Automatic transmission dipstick, R129

[Torrean]

Hi Guys, strange question, does anyone know the length of an Auto transmission dipstick for an R129. I have a dipstick but it seems too long.
Thanks.

They are all too long , designed for different dipstick tube heights . It’s the stopper before the plastic measuring part that sets the height

Measure the oil when it’s hot , engine running , gearbox in Park on a level surface

50 k + cars and no way to check trans oil without purchase an extra !! Should be a warning really.

Thanks guys, the issue I have is that I’m not sure when I hit the bottom of the sump as I can feel a resistance when I think I have reached the bottom but if I push the dipstick it goes in further, only this I can think of is that the dipstick is bending at the bottom, hence the question about the length of the dipstick.

Bit late when you have bought the car buddy

You aren’t reaching the bottom , the lump above the last couple of inches is stopping in a recess above the oil , the going in further is the flexible tube bending above .
What oil Reading are you getting

Is this the 722.6 gearbox? There are several others used on 129s.

That’s the problem, I don’t know!

I’ll need to check.

I’ll need to check.

Is it the V6 engine?
If so it's probably the 722.6.
You should be able to tell from a VIN decode.

Yep, that’s the one!

Ok 722.6 then.
On the dipstick there's a plastic lump at the point the flexible metal part joins the flat blade. That is designed not to go past the measuring point.
The initial resistance you're finding is probably the end of the stick hitting the join at the end of the tube before going into the gearbox.

Thanks for this info, sorry for being dumb, at what point do I stop!

When it won't push in any further!

So you didn’t look at the end of the dipstick when you pushed it in ?

 

[LostKiwi]

If in doubt measure the length of the tube and compare to the dipstick. That will tell you where the join is.

 

[Torrean]

Yes and the level seemed fine

Change the atf and filter every 40k miles buddy . Good job
