I was at the wreckers today and couldn't find any 6 cylinder Holden's with a drainage hole. They were all just like my KE55's box.

Drill and tap a hole :P

How many times do you change your auto transmission oil ?

 

Not that often so i don't see the point in hunting around for one with a drain plug, Not hard to one corner down and drain into a tin.

 

Drilling and tapping a hole wont work, The pan is too thin and there wont be much thread to hold it. Drill a hole and get some one to weld a nut around the hole. Use a magnetic drain plug with the same thread as the nut.

But if you had an equal sized cork to fit?? :P

 

I still would prefer having a drainage hole.

Our ae71 has a drain plug.

They still use the holden trimatic don't they?? If so I'll look into them.
