Ok so I see there are some universal oil cooler kits out there but how do they work? I understand the fluid goes through a heat exchanger much like the radiator. However how does the fluid pressurize into the cooling element? I’m pretty sure our transmission are “slap” system lubrication. Would I need an electric pump of some kind? Would it be possible to do this for the rear differential as well?

 

Transmission coolers are radiators and are universal for automatic transmissions which are pressure lubricated. They're typically built into the engine coolant radiator so they're not obvious..

Yep you need a pump. Neither the gearbox nor differential get hot enough to need one on our cars that I can tell. What makes you think you need one?

For the differential, you would need the EVS/Greddy cover, it has has extra holes to allow for a cooler.

 

I don’t think I need one just spacing out from work and letting my mind wonder lol. But thanks for the info fellas

 

S2000 has an oil pump for gearbox

 

There is an oil pump in the transmission?

 

Yes there is.

 

Never knew this until minutes ago.

Like Noodels wrote: S2000 has an oil pump for gearbox. It's inside. And I couldn't find any pressure specs, etc in a quick search. Be interested in seeing a lubrication diagram of the gearbox to see if an external oil cooler could be fitted and if the pump, which looks small, has enough pressure to push oil thru one.

You don't need a oil cooler on manual trans, only autos.

 

Would the rear diff benefit from a cooler set up? The reason I am asking is I am looking to build a rear diff this winter and I want to build it as good as I reasonably can. Cusco 2/1.5 LSD and 4.77 gear any advice on that set up would be good also. I’ve never rebuilt a diff but I’m buying an extra diff and diving in
