Dennis,

The overheating 5-speed auto and reflash to address the issue is only appliacble to the 150 Prados. There is no issue with the 120 Prados.

Re: Auto Oil coolers

and your 120 should already have an oil cooler

120 D4Ds do not have an external transmission oil cooler - they just use the radiator.

Well there you go, learn something new everyday. I didn't even look at his signature to see it was a D4D. ops:

Re: Auto Oil coolers

try http://www.derale.com they have a variety of oil coolers , i'm geeting one for my 2006 VX , V6 ,5 speed auto , as last friday i took the car for a spin on sand dunes , temp was 30 , the over heated transmition oil went on 3 times.

i might even go for motor oil cooler and power steering heat sink too.

another company http://www.flex-a-lite.com/auto/ i didn't tried any of their products before .

Re: Auto Oil coolers

I'm also keen on doing this mod.

I have had a quick look at the PWR oil coolers, only cos they are mentioned in 4WD Action, but I couldn't figure out which one would suit.

An email to them would help...

Otherwise I could find a decent transmission specialist in Perth to fit it...

the diesel 120's weren't fitted with an external trans cooler.
for a diesel, stick with a small or maybe a medium cooler.
you don't want to over cool your auto fluid otherwise it will hold onto gears longer as it thinks it is cold and try's to warm-up.
i have had a meduim fitted for over a year, but my trans feeds direct to external cooler then to vehicle radiator (so it can re-heat if needed). my trans oil temp sits around 60'C at the present (cool air). i have had it at 90'c for about 5min under heavy load, but cools quickly back to 60-70. this is what i wanted it to hover at and it works fine for what i use the prado for.
others that just tow might want a different set-up/workings.
unless you need a cooler, i suggest not, as it's just something else that could go wrong, or if ill-fitted could rub through AC condensor and then $$$.
i also have a small power steer cooler fitted as i have overheated PS twice before. haven't since.

Cheers Damonat!

You definitely have provided the other side of the argument.

Over the last while I have continued to read that fitting an auto oil cooler is a must-do mod for auto 4WD's (they keep harping on about it in 4WD Action - I know people have mixed feelings about this mag), so its good to hear other people's opinions.

I don't do any towing, mainly cos I got nothing to tow, other than the odd trailer run. So its good to hear your point of view - very informative.

Re: Auto Oil coolers

I put my cooler on about a year ago. It was one I took off my Commodore a few years back. Just an after market one.

I didnt have any trans cooling issues, but the beaches here are quite soft, and I do tow a camper up North occasionally.

The engine does run slightly cooler on the gauge on a long run when towing.

Many a Prado running without coolers, that are towing more than me, and I dont hear of many cooked transmissions or overheating issues. It probably just comes down to personal choice.
