Auto Trans Oil Cooler

[wht510]

What are you running?

How well does it work?

Do you have pictures?

[Sunkist]

im running exactly this

and its doing fine. set up in between the FMIC and rad. i think mine is looped in after the rad.

its a PWR for V8's

[wht510]

Nice. Dollars?

I assume you mounted it yourself?

And how much did it increase oil capacity?

i got it of a mate for a birthday gift, but they go for $150 as the link.

yeh i mounted it myself, just got some bendy mounting brackets from Bunnings and i was set. i installed jethros too.no more than half a litre at most.

That listing says RRP$149, but they're selling it for $154...

ebay fail.

I have no doubts this is a super dumb question but is there any difference between a transmission cooler and just an oil cooler?

[chuckie]

Trans oil should have Thermostat,

as it runs hotter then Engine oils.

so its great putting bigger cooler on but trans runs at about 100 too 110 degs,

if you can find Mazada FD cooler it has built in thermostat ,you may want too look at Filter kits for trans as it will prolong trans oil life.

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?

Apparently RX8 oil coolers have a thermostat built in. Going to have to do some hunting!

[chuckie]

may be NEW but at WHAT COST HATE TO THINK

I got mine 2nd hand,both in good nick too,

i run one on Trans with Filter kit ,

one on Engine oil with remote + stock filter,

has made a big difference to oil colour as before it was not red as it should be,

iam about to do Trans oil sample so i shall post up what i find out,

any filter will help oil life ,my steering cooler is a big winner as its red still ,before i would change oil in top tank every week & it would be Black.

I had the 6cyl version of the PWR trans cooler (like the one Aaron showed).

Mounted it as you can see below... until I upgraded the intercooler.

I reckon Chuckie's suggestion is pretty good although there have been no ill-effects with a large trans cooler on M35's.

I use a 16"x16" item designed for drag racing in mine. temps generally run 90deg C on a hot day. this is in a built jatco 4sp in the subaru.

Great posts guys.

Chuckie, I'm interested in the results of your tests!

I think it's a great idea to run a filter too. Never thought of that...

Let us know if you find any part numbers or Ebay sites which stock this.

I might be interested.

[Chris Rogers]

RX8 ones pop up on ebay from time to time. they are NOT cheap new. (think 4 figures.)

good luck,

best advice ever chuckie!

and idea on the physical size of that transmission cooler? it appears to have the right fittings etc to plumb it straight in

[southern_tango]

Sounds interesting (just relocated my stock one) here I found a place that has the RX8 one

Cheapest I can find for an RX8 oil cooler - http://www.mazdatrix.com/getprice.asp?partnum=14-700D-N3H1

Thought I'd ask SK about his thoughts on it. His brief response was "There is no such thing as too cold transmission fluid."

I don't know what to believe/think. In Australia does it really get cold enough for this to be a concern?

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.
