Auto Trans Oil Cooler

[jasevr4]

given I can put my hand on mone and almost get a burn off it - yes it is needed and I do agree with teh above statement. heat kills these things - I have a $4500 bill to prove it.

Yeah for sure I support that, they get HOT enough for cooling to be a concern. But what I'm wondering if the oil taking too long to warm up is a concern. My new radiator won't have the "cooler" (warmer) built in, and whether or not that is a concern on the cold mornings I'm not sure.

While I'm at it, what fitting size do we need for these things?

[zei20l]

of course they would be too hot to touch, they shed heat into the engine coolant which ranges from 80-110 degrees lol

just plumb one of the pipes next to a radiator pipe (even touching it) and youll get a bit of heat transfer

if this theory works, i'de just be mounting the external cooler so it is physically touching the radiator core. or is this bad?(dont flame me it isnt how mine it lol)

[zei20l]

thats how i have mine setup right now. im sure there isnt MUCH heat transfer, ideally youd want the pipework inside the radiator fluid, but this is the best option i had till my new radiator goes in

[Sunkist]

thats what i would think to be the best solution to get it to running temp sooner, if thermostats are being difficult.

Looks like B&M SuperCoolers are the go.. http://www.bmracing.com/PRODUCTS/Automatic-Transmission-SuperCoolers

‘LPD’ or Low Pressure Drop feature includes two bypass channels nearest the fittings to allow fluid to flow freely especially when cold to prevent lube system failure.

the B&M stuff is pretty good man!

got some prices?

[jasevr4]

Around $120 delivered off of eBay.

f**k not bad! will keep it in mine if i need to change it for the new rad.

That's for a 11x7.25x0.75in unit which seems pretty similar in size to what everyone else is running. They have larger units but the fittings are larger too which would be a bit of a pain. If you're in a lot of city traffic they also have the same coolers with fans on them.

[Sunkist]

yeh i was thinking of re mounting mine to the inner wheel well with a fan. but yeh i think it may be over the top

Chuckie this is exactly what I want. Can you still pick them up new from Mazda? Or do you need to find a second hand unit?

I was taking to a mate about this exact cooler last night; he reckoned Mazda charges $400 brand new. Supposed to be an incredibly efficient cooler for it's size.

if youre not moving there is probably no point in having a fan on a transmission cooler. once youre moving and you need the cooler to work, well, youre moving!

Unless you are sitting in peak hour traffic in summer.

But if you mount it above the reo, the engine fan will pull air through it anyway

[zei20l]

yeah there is always air movement there

also, with the AC on, youll get a little more air movement!

[jasevr4]

Yeah exactly. I'm going to order one this afternoon. FYI the part B&M number is 70268.

I have one of these in my R33 with modded C4 auto.

But am now worried it wont be enough so am looking to get a 30 row oil cooler core and use that with a fan. I also have a transbrake and was told to box will see 120+ degrees within a few seconds on the transbrake.

What does everyone recommend as a thermostat?
