1960 suburban 400 transaxle drain plug size?

[mhlmeader 689]

Hi folks, in the process of unsticking a very stuck tranny drain plug I marred it up pretty darn good.  Anybody know what replacement size to get? And where? Thanks

I'm not familiar with the transmission you have as all of ours are newer but if you take it to a hardware store I think that's just considered a standard replacement part. They should be able to match it up.

I'm thinkin 1/4 NPT here Buff Bill . You can get the hex head ones but a square head plug will work good.  

 

Oh and Ace is the place.... or any hardware store or big box.  Hex heads from McMaster.

I have always thought they did not have a drain plug.

That is actually the fill level plug.

 

You need to remove one of the lower bolts that hold the tranny side plate to the center cast piece. This will allow the oil to drain out. When you fill the tranny, add oil until it runs out of the hole that you removed that plug from. The plug is an 1/8" npt pipe plug.

Correct thinkin now that I have a cocktail in my hand ...I drill the bottoms and install a 1/4 NPT magnetic plug..... On trannies I have to open.. @stevasaurus would approve of removing a case bolt to drain. I could swore one of mine had a drain plug on the bottom??? Or am I thinkin a fill  plug on the top?? Hang on whilst I refresh my glass! 

[Racinbob 11,232]

Dunno Jim. No drain plug on the bottom and there's already holes in the top for filling. I couldn't get the level plug out on mine either but then again, I didn't try too hard. The only reason I tried at all was so I could put a stainless plug in it.

Case bolt to drain and 1 1/2 quarts of go juice and be done with it.

Let me refresh your glass Jim.  If your were drinking Rock & Rye, you would know that there are no drain plugs (except for the bottom bolts) on the 5003 and 5010 transmissions.  Also, no fill plugs on the top...use bolt holes for seat or the shifter hole.

Suggesting...Rock & Rye with that cheese.  @WHX24

If Cindy would let me keep a horse or three in the house I could just look over from my stall and see what's on it for drains. ... ok now we need quit messing up Buffalo Bill's thread or he is gonna be saying it puts the drain plugs in the basket!
