I went to change my trans fluid over the weekend (time to put her to bed for a long winter's nap), what size is the drain plug? I was able to remove it using an allen, but it didn't seem to fit quite right.

The oil and primary plugs are standard bolts, but this plug has no head on it, just a slot/opening in the end.

It's for a 2010 Fatty.

Thanks.

 

Mine has a hex socket, 5/8" just like the other 2.

it's an 09 but should be the same, I would think.

 

No, mine has no head on it, just a slot in it. And it has no gasket on it. Very strange. That's why this is so puzzling.

 

My. 2012 deluxe has a hex head on it. Are you sure you pulled the right plug?

 

Yep. Oil came out and trans dipstick showed no oil.

 

The tranny plug U pulled,, its the one between the shocks, right,, or,,????


this link shows u how to do it.

No. The diagram from the manual looks like this. It is in front of the trans and the shocks (by about 6-8 inches).

 

Ok, I'm officially confused. The diagram you showed IS the transmission plug, but it is located in between the rear shocks and has a hex head. Just draw some shocks around the diagram you have and that's it.

The only plug 6-8 inches in front of the shocks is an allen hex plug on the right side of the engine, and should not be removed.

 

M'en F'er! I've searching the web, and I think I pulled the sump plug! Now what? Did I ruin something by pulling the sump plug?

How come the damn manual didn't just label the shocks and so forth in that diagram?

I'm so confused now, because the tranny oil dipstick was clean when I pulled that (sump) plug and drained the oil - I double checked because I thought that was an odd plug and an odd location.

This sucks!

 

That sux. I think there's a thread somewhere of someone suggesting plumbers white glue on that plug. It's tapered from what I've read so be careful torquing on it.
