I need advaice on a transmision cooler for a gs400. I be putting in a swift racing torque converter and will like to know what is the best cooler to use.

 

DA,

Did you try the search feature to look for 'transmission cooler'? You'll get plenty of threads on this topic. There are lots of nice options, some more expensive and involved (but still not $bad) like PP's B&M. I have a Permacool, many others have a Hayden.

I found these threads (among many others) in about ten secs

Any decent cooler will do the job.

 

cool thanks guys

 

I just got my TC also. But I've talk to a few Tech/Mechanics who confirm something that sounds odd but is supported by PI themselves.. I was asking the same Question-What Tranny cooler should I use?
The Mechanic said "Why would you want want one? You don't need one..." I was like Whhhhhaaaattt ??????

They said that - "With a better and more efficient/advance TC -its better design and low mass actually produces LESS HEAT than stock and that a cooler isn't necessary!"

I can quote you where PI has it in there FAQ:

IS AN ADDITIONAL OIL COOLER REQUIRED WITH HIGH PERFORMANCE CONVERTERS?
An additional oil cooler is not required for high performance converters used in typical street or strip applications although added cooling is a good thing. Care should always be exercised when runup is made at the start line. Any excess time at stall puts the converter at risk due to heat build up. This type of heat buildup would not be saved with a cooler due to the time involved to get rid of the heat. If a vehicle is to be used in towing, an added cooler is a must. However, for normal use, added cooling is not required. The better the converter is designed, the more efficient it will be and the lower the amount of heat that is generated

So now what? To Cool or Not? is the Question...

Thanks,

IMO - it is not needed with 'normal' driving (I ran my GS w/TC without one for a year and a half with no issues. I added mine because I knew I was headed to a quarter mile track and wanted the extra insurance.

That's really what the tranny cooler is - a little extra insurance that when you aren't driving 'normal' you don't create excess heat and damage your transmission.

 

Hey Dave,

Does 'Normal Driving' Consist of Driving Hard every once in awhile, playing around and perhaps an occassionally race on the street?

I am not going to the Track with it.. And If I do I may make 2-3 runs for fun.. Do I really need a trans cooler?
How about even hot Southern Summers included in 'Normal'?

Thanks,
Don

 

That's pretty much what I did for the first year.... But these things are less than $100... why risk it?

 

I think its a great idea, but i have the worst luck with stuff. My theory is any that can go wrong=will go wrong.. ITs bad, but Thats why I am so careful before making each modd. I also read on another thread that Pearl Poewr was having overheating problems after putting on the cooler- Sacres me!!

What to do?

Thanks,
Don

 

Oh yeah? Hmmm... if you have a link that would be good. I'll do a search anyway. I have PearlPower's cooler KIT on my car!

I've had my cooler on for probably close to a year with zero problems. For what it's worth I'm glad I've got it.

 

is there any noticeable change in shifts?

 

With a cooler?? No. The cooler's job is to keep the tranny fluid from getting too hot and causing the tranny harm.

 

Don't these cars already have a cooler as standard? It's an oil to water cooler inside the radiator.

 

I once had a very large cooler on my car which resulted in some cooling issues. However, with a standard cooler available at any auto parts store, you should have no problem whatsoever. My cooler has been on for over a year with no issues. Just added insurance for piece of mind and to prolong my trans.
Keep in mind that 99% of trans failures is due to overheating.
The standard cooler in the radiator only helps a little and should not be confused with the real thing. For best results, run both the aftermarket and your radiator in sequence for maximum cooling. Your transmission will love you for it.

 

Thanks PearlPower - datz waddum doin'
