crazyxa Member 84 Member For: 17y 1m 6d Posted 18/08/15 08:16 AM Share Posted 18/08/15 08:16 AM Which people? PWR unit is a heat exchanger. It functions exactly the same as the OEM unit. Only difference is it is made to high manufacturing standard unlike the random crap one that Ford uses. 1 Link to comment Share on other sites More sharing options...

Will be getting zf built soon. So want to "bulletproof it"Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

I hope it's not all the "experts" on facebook 1 Link to comment Share on other sites More sharing options...

The cheaper one is the gauranteed to stop milkshake method...BUT its the one that can run "too hot or cold". With the ZF being super fussy with temps, I was advised to go the PWR heat exchanger kit...cause mimics OEM functionality and is larger and looks better made than Ford exchanger. But there is still people who use the furious kit without issues apparently??? If these "people" mentioned by OP were indeed referring to the PWR heat exchanger kit...then they are stupids Link to comment Share on other sites More sharing options...
barnz Member 3,047 Member For: 10y 4m 30d Gender: Male Location: Brisbane Posted 19/08/15 01:11 AM Share Posted 19/08/15 01:11 AM Most decent kits come with a fan and temp control that won't bring it on until around 90 degrees which is operating temp for the zf, switching off again at around 85 degrees and will do a good job, a better job than an exchanger of keeping it in that window under harsh conditions. I can see how warmup could take longer, but its kind of a moot point. Don't flog your car until its warm.Normal driving conditions well, I don't know I haven't had a trans cooler on a zf but I will be going that way when I service soon, so will monitor temps under normal conditions when I do. I don't trust the OEM unit, PWR unit is obviously better quality but overpriced IMO, I mean you can buy a fkn intercooler off them for just about the same price...whilst I do maintain my car well, I have to it cops a hiding so I think the trans cooler is for me. Plenty of people running them without issue and its been years now so safe to say it works fine. The myth they are terrible for your gearbox is exactly that...Now, cue heat exchanger fan boys that will blatantly ignore the fact they aren't real good if your trans actually needs cooling and will focus on the fact they keep them within OT under normal conditions and warm your trans up quicker if you live in fkn Alaska.... 1 Link to comment Share on other sites More sharing options...

Weight alone is a good indication of quality vs the stock unit. 1 Link to comment Share on other sites More sharing options...
barnz Member 3,047 Member For: 10y 4m 30d Gender: Male Location: Brisbane Posted 19/08/15 01:39 AM Share Posted 19/08/15 01:39 AM (edited) No I haven't nor did I say they weren't of better quality? Just expensive for what they are man...Mine flares a little when cold with the stock exchanger, I expect this probably goes on for longer with an air cooler. Obviously engineers do things for a reason and the exchanger has its merits. I also know that you know if any box is getting a hiding for any extended period of time(track use, "legal" hill climbs....towing ect) an exchanger setup is not going to look after it. So either solution is a compromise in some way, correct?Well being a prosparkoligist I had previously had an idea that seems a little to easy for no one to have thought of it yet...but I'm still not going to share just yet as it may just be a winner. Doesn't involve water for a start but would warm up faster than the exchanger with all the benefits of a air cooler....trans fluid isn't conductive is it...I mean at all? Its quite important that its not so I really need to make sure of that first and get around to making a test kit...I have another idea if that won't work but complexity and cost would probably rule it out...

Pwr kit gets its upto temp and the oil/air cooler will help out when smashing it around track when it wants to get hot. Maybe it might work? 2 Link to comment Share on other sites More sharing options...

Did the same in our territory, but used a new genuine heat exchanger. We tow a bit 1 Link to comment Share on other sites More sharing options...
