I didn't bleed mine when I installed the aux cooler. Just hooked it up, ran it until it warmed up to open the bypass. With my second cooler and MagnaFine filter, it pumps a quart in about 15 seconds.

The smart money is on the person who checks the fluid level after the first few minutes with the fluid warmed up. /ubbthreads/images/graemlins/smile.gif

There is no need to bleed the trans lines.

 

Why not just add the True Cool Max in series with the other coolers? Many others have done it without a problem, you should still have the required flow rates. It gets hot in Phoenix, you can use all the cooling you can get during the summer months.

 

thanks everyone! im gonna try all of them hooked up to see what temps i get. i heard john wood said the inline tranny filter is not nessessary. is that true?

 

That's right. I didn't see the Phoenix part. /ubbthreads/images/graemlins/blush.gif I have the OEM followed by the Flex-A-Lite, and still get the flow rates I mentioned before.

I ran a pressure-drop model (PIPEFLOW) before I did the mod, which showed it would be good. (All add-ons are via 1/2" TRANSMISSION COOLER hose from NAPA.)

 

what happens if you put too much tranny fluid in?

Very short term, nothing. Let it go and bad things can happen. It will foam, and foam doesn't carry heat away very good. Heat kills trannies. I know first hand, long story so I won't bore everybody, but it will kill your tranny.

Not exactly, but sorta. /ubbthreads/images/graemlins/cool.gif

Provided you have a brand new John Wood tranny and torque converter, and provided he replaced the tranny coolers with brand new heat exchangers when he installed the new tranny, then and only then can you get by without the Magnefine in-line tranny filter.

Brian Thompson from BTS says the same thing.

But if you don't have a brand new tranny, torque converter and coolers, then you should follow Ford's instructions to their techs. Any time a Ford tech works on a 4R100 tranny, they are supposed to make sure it has a Magnefine filter installed in the cooler return line. If it doesn't have one, they add one. If it already has one, they replace it with a new one.

The purpose of the Magnefine filter is to catch any debris from wearing clutches or a blown-up torque converter or tranny before it can flow back into the tranny and cause even more damage. If the torque converter goes south, it will take the tranny with it if you don't have that filter.

Plus the magnet in the filter catches magnetic dust in the ATF. Mine captured about a teaspoonfull of magnetic dust in 30,000 miles. That gritty dust floating around in the ATF causes increased wear of the tranny parts, but it's too small to be captured by the stock tranny filter.

You can get the Magnefine filter at any Ford store, or online from www.emergingent.com/magnefine - Click on "online store", then you want the $19 jobbie in the 3/8th size. Replace it every time you change the ATF. Remove it only if you get the $4,000+ Full Monte from John Wood, BTS, or Suncoast. /ubbthreads/images/graemlins/warmsmile.gif

Nothing good. What Paul_B said. /ubbthreads/images/graemlins/frown.gif Better to have not enough than too much, but best is to make it just right. /ubbthreads/images/graemlins/cool.gif
