Hey guys,

I'm having some issues with oil pans (sumps) for the TH400...

There are deep and "normal" ones for the standard V8 TH400. These will fit the tranny, but the problem is, they aren't deep enough for the V12's transmission. My factory sumps are about 8 cm deep. The ones offered for other brands as a DEEP sump are like only 6 cm deep, tops. Most are more shallow.

Has anyone managed to source a sump with drain plug for the V12 with enough depth so the V12 won't cook the transmission (more fluid = cooler transmission = better life expectancy)...?

Cheers

Damien

 

Here's a 4" deep pan.....

Cheers for the link Doug, that won't fit though. The distance between the tubes and the top is too short. The centee bolt will catch and cause issues. Needs to be about 3-1/2" deep inside so nothing catches...

 

This fits mine OK, Daim:

thank the stars , for USA type modifications, AT A reasonable cost!!

 

Awesome! Jegs also has a standard sump/oil pan... Seems like the same just without thouse front openings...

At 3-1/2" it would be perfect... As I need a new selector shaft, it looks like Jegs is all the way to go...

Could you not drill a hole in the existing pan and weld a nut to the outside and plug it with a bolt as your drain?

 

The problem with a cast pam is it will crack if it hits anything. The welded Moroso pan will not. Also the drain holes are at the downstream end on the Moroso pan, all the others will leave quite a bit of fluid in the pan.

 

I'm not so worried about the fluid left in the sump, as every fluid change involves a filter replacement and therefore the removal of the sunp, as long as I can drain 'most' the fluid I'd be happy.

Regarding the cast vs. pressed/stamped/welded pans... Hard thing to decide on. Most modern sumps are cast. Even engine sumps... So I guess that may have been imporved? But at the same time, for something to smash into the sump, big enough or with enough force to crack it, then it would have causes some damage else where before hitzig the oil pan (which is so far back).

I don't plan on speed ing with the V12. A steady 130 kph will do me... Even with the unrestricted Autobahns here. The only worry I have is, where to fit the sump magnets... Aluminium isn't magnetic and I don't think a magnetic plug will do enough to catch the shavings (though mine should have less, as the running in phase for the planetary gear etc. is long gone (1989 to be precise ). So anything which is found can only be tiny which would get caught in the filter anyway...

 

The friction material is semi metallic, so as the frictions wear that material is caught by the magnet. You could always epoxy a magnet to the bottom of the pan.

 

Problem then is removing it for cleaning I might epoxy a piece of steel though and then the magnet would 'stick' to that...

 

I'd put the magnet on the drain plug. When you remove the plug the nasty stuff comes along with it. The just wipe the crud off the plug. Easy peasy
