Technical Speedo drive blanking plug

[2TAD2]

Hello all, my first post on here. Q* On a 2008 Fiat 500 sport 1.4 6sp manual, there seems to be a slight oil leak around differential.
APPARENTLY THERE'S AN UNUSED SPEEDO DRIVE HOLE THAT IS BLANKED OFF WITH A PLUG, THIS SEEMS TO BE WHAT'S LEAKING.
HAS ANYONE REPLACED THIS PLUG?
I've done a big web search but can't find anything about it or a replacement plug just pictures. Any help appreciated thx

Welcome to the forums.

That looks like a blanking plug that is a temporary plug which is removed and discarded when the proper component is fitted (Is that one threaded?) You say unused, but is it a gearbox that fits many cars, and some may have a speedo cable?
Others may have more info, but a more permanent plug seems the order of the day.
Sorry I can't be of more help.

As far as I know its an original plug not temporary and the speedo is read from the ABS.
The 2008 Fiat 500 1.4L with a transmission is equipped with a C510 series manual transaxle, specifically the C514.6 manual transmission. The "6" in the designation denotes a 6-speed layout.
I don't want to chance trying to remove it before having a replacement plug.

It's item number 267327144156

I've a 2008 1.4 6sp manual. I don't remember seeing a plastic plug, but not home so can't check.

Might be something special for Oz to stop fluids falling out when inverted .

Thought you'd have looked in ePER.

Look in transmission (212) part number 55189930

Hex countersunk plug.

Thanks but that is a sump plug.

Try direct messaging forum member @Fortunes Gate on here. Hes a gearbox expert and may be able to advise even from this distance?

 

[jackwhoo]

55187172 is correct fiat part number

The seal is by o ring on the plug.
Unless a real leak rather than just damp leave it alone.

Or just put a smear of RTV sealant on the threads!

Have a look in ePER. It's a transmission plug.

55187172 is number for new plug including it's o ring

Don't think the number is correct for the OP car.
I've relooked in ePER under my VIN same model engine.

But could be wrong.

It's the part number for part pictured in post 10

The op is looking for plug for speedo drive hole

Something for me to look about when back home. Old age or what, but I don't recall seeing a plastic plug .

You can't see it in car normally, it faces the firewall and faces upwards. Had to take pic holding phone over it.

FINALLY!! THIS WOULD BE IT. Not threaded and held in place by screw below locking it in. Makes sense now. The part you "see" when installed is just the tip of the iceberg! Hopefully just a new "o" ring will fix it and I can get the plug out without damaging it too much. Thx koalar.

I don't think it's a thread.

See koalar's post, reckon he's on the money

Thanks Jackwhoo. Early coffee and Google part gave me " Broken hex bolt near driveshaft causing gearbox oil leak – Fiat Panda 1.2 (169) ".

The OP might find of interest along with Koalar input.

ePER doesn't list this for my car.
