Are they not the same cooler as the autos? If so an additional ATF cooler like Davis Performance Landys etc which just sits behind the grill. Some also fit the P38 V8 ATF cooler in place of the normal one - I havent done that one though.
The ones I have seen are just a steel pipe which runs forwards to the front of the engine (or thereabouts) and back to the gearbox. No proper cooler as such.Quote:

Still, the question was re R380's. Djam1 is right, the suffix L seems to be the one to get. Having had two R380 failures, my take is that the oil volume is critical. The original failure was due to a weep from an oil cooler pipe, along with a long drive on the highway, mostly in fifth gear. This was in a relatively new ( not reco ) box. Oil choice is also vital. The oil Dave Ashcroft specifies is hard to get locally. There are many opinions regarding oils for this box. Fred Smith told me Manual Gear 70. Many folk say ATF. We're using Nulon synthetic ATF, but not behind a Holden V8.
In another life I pulled down a number of Holden all synchro 4 speeds that had been behind 253's. They were stuffed. They were relatively cheap to fix though. Maybe that's the point.
If you've got the bucks, get in touch with Dave Ashcroft. He's very helpfulll. Tell him what you're doing and get him to build it. The one he did for us is a beautiful box, and his prices are good. Do a LOT of homework before you import it though. The import BS cost us more than twice the price of the box. Not Ashcroft's fault, but needs bearing in mind.
I was going to say, they are 304 cubic inches! 304nm is pretty lame for a 5.0L motor, especially considering the 4.6 Bosch motor in my P38 makes 406nm!
ATF is generally not up to the task IMO, unless you can get a GL4 spec ATF (like Castrol TransmaxZ) and then a dedicated MTF like Redline MTL/MT85 or Castrol Syntrans 75W-85 will still provide better gear and bearing protection.Quote:

The ATF has been in a while now. It's done some work. I'll be interested to see it when it's drained.
I couldn't speak highly enough of Castrol Syntrans for the R380
Yes it may be a loop of tube, but it adds volume to the oil quantity and uses the chassis as a heat sink. It is also why I suggested you could increase the size of the oil cooler in my first post.Quote:
