Has anyone ever done this??

[FunBlazer]

Use their AC condencer for a tranny cooler, when they removed the AC??

 

[FunBlazer]

Someone must have tried this, I need to know if it worked , cause I want to try it on my Blazer tomorrow, if someone has tried it and if it worked please let me know. Thanks

Not me.....

I helped my buddy set it up on his dodge. Worked like a champ. The tranny never, ever, overheated.

 

[FunBlazer]

How come everyone dosn't do it then? It's a whole lot bigger than one of thoes coolers that you buy in the store.

ur tranny needs to run at between 170*-190* to work most effiently. having a cooler that large keeps it too cool. get what im sayin??? hell, a regular tranny cooler keeps it right where ya need.

cool
I would have guessed it wouldnt handle the pressure, not that I know how much pressure flows through the cooler lines...

 

[Sandman]

If your worried about it being to cool you can run it back through the radiator so that the water can warm up the fluid.

 

[Sandman]

Isnt the low side of the AC system something like 32 pounds? I would not guess that the tranny cooling lines are much more than that. But like you I do not know what the pressure is either.

 

[FunBlazer]

Well I did it today, and I don't think I'm gonna keep it that way, cause I realy don't like to use rubber hose. I have a decent size cooler and the tranny lines screw into it so I'm gonna put that on instead. I heard that pressures can get as high as 290psi in reverse, I can't conferm that though.

 

[harry]

how about using it for a power steering cooler?

 

[wrathORC]

Well, if that was the case then my factory-installed cooler with fuel line for hose would have blown off a long time ago.

Cooling lines don't get anywhere near that PSI, but using rubber lines for ATF is a great recipe for an engine fire if you ask me.

Already had a hose heat fatigue, and rupture, spraying a nice stream of ATF on the exhaust manifold. You really don't have much in the way of choices in the cooler line issue, even the GM factory C/K tranny cooler I bought used rubber line. I just don't think its a very good idea, like rubber fuel line. If it can be avoided, great, but unless you custom make some lines, (you can) you don't have much choice but rubber.

Usually about 150 psi on the high side. Nothing steady though because heat and engine speed will change the pressures.

Also keep in mind the function of the cooler, it is not necessarily to keep the trans fluid cool, but to regulate it. It works like a charm in the radiator, but if you need an auxiliary cooler, I recommend getting a good one designed for Automatics and use steel lines.

Have you tried a $30 tranny cooler from Autozone? It comes with adapters and mounting hardware, just do that.

 

[Sandman]

Thats what I did. Its a B&M stacked plate cooler. I run a 2400 Stall converter so mine likes to heat up some. The cooler does just fine except for long periods of crawling on rocks on a hot day. It went up to 230 once. Normally stays at 160.

 

[Blue85]

The tranny only puts out about 150-200 psi, when you have a lot of throttle. The pop-off valve on the high side of an A/C system is usually 350psi or more, so the condensor must withstand that pressure. This should be the setup of choice if you tow with a 700 without lockup and with a high stall converter /forums/images/icons/smile.gif . Of course, if you tow in any kind of heat, you'll want the A/C to work anyway.

 

[m j]

is it full line pressure?
I dont care about autos enough to do my own homework on them LOL

 

[Blue85]

That's a good point, I don't know if the cooling lines see full pressure. At any rate, the condensor is probably good to a higher pressure than the rubber hoses that come with most tranny cooler kits.
