Speedmaster cover
Anybody using this transmission cover?
Is it good?
Does it fit a stock '88 Firebird V-8?
I like the fact it has a drainplug, (and it's not to expensive for me to have it shipped to my country...)

Re: Speedmaster cover
No magnets in it, like the original cover, would that be a problem, or can I just do without those magnet(s)...?

Re: Speedmaster cover
The magnet should handily set in the pan, holding to the dran plug. Keep it.

Re: Speedmaster cover
New cover is aluminum, so magnet won't stick to it...

Re: Speedmaster cover
A couple of options with an aluminum pan would be to either epoxy the\a magnet to the bottom of the pan, or get a magnetic drain plug.

The magnetic drain plug is a good option, thanks for the suggestion.

Re: Speedmaster cover
I thought the forced acceptance of refugees was the straw that broke the camels back. Perhaps he was referring to your mention of Tax, shipping, and customs. Which are pretty universal globally, except here, where we crutch other countries' exports by seldom charging T&C on single item orders.

Re: Speedmaster cover
When ordering parts at Amazon, or Ebay, or Rockauto, shippingcosts to The Netherlands(EU) are high, and over the total: 21% custom/tax...
I paid about $30 for the $10 plug above...
And that's because it's comming from a non EU country......
(BTW, I paid about $90 for the pan, tax and shipping incl.....)

Re: Speedmaster cover
Search "Metal/Rubber Drain Plug Gasket" on dormanproducts
They list multiple manufacturer PNs for cross reference.
365274 is 12mm I.d., has 8 part numbers, 6 are GM. Maybe you can cross reference those to parts stocked in your country.

Re: Speedmaster cover
Thanks for the suggestion.
I bought a couple of M13 copper gaskets on Ebay UK, should do the trick.

Re: Speedmaster cover
Copper washers didn't work, magnetic plug leaked.
Metal/rubber washer worked great! ( same washer as sump plug btw...).
Cover is finally on, it holds about 1 liter ( ~1 pint..?) more transmission oil..
