Hi all

After doing some research on here regarding the heat exchange for the zf transmission failing I was convinced to purchase the PWR one and fit when I service the box. I spoke to the local tranny guy today and he recomended not to go for the PWR one and just fit a heavy duty one as the PWR one will yes stop a milk shake happening but cooling wise not much better than the standard one and reckons there sh*t when it comes to cooling. He only uses genuine oil and said he sells it for $37.50lt bottle or can sevice supply & fit genuine metal pan ,filter, oil, cooler and braided line for $950 what are your thoughts guys

This one is a can of worms.

I went for the pwr heat exchanger on our N/A 6. If I had a modified car up to about 300rwkw I would go for the PWR heat exchanger alone as it enables the trans to get up to temp quick and keeps it running close to factory temps.

BUT if I had a high powered car I would go for the PWR heat exchanger and a large cooler with fan (thermostatically controller) in series with the PWR. Then you have all bases covered.

But I drive a manual and dont have to worry about auto issues.

mate of mine running the PWR part has had nothing but praise for it until the last happy laps session our at QR whereby he cooked the trans fluid enough to go into limp mode several times.

it's coming out for a cooler.

Maybe not fair on the exchanger because this thing has near on 500rwkw

Dont take it out. Just add a cooler. 500rwkw at the track is the top 1% of ask for the trans and cooling system.
