I would put it in the return line and temporarily plumb a pressure gauge in the pressure line to monitor how it is flowing.

They do.

Just like your house plumbing... if the valve at the curb is shut off by the water company, whether you turn the valve on the faucet doesn't matter.

 

I ordered an add-on external tranny cooler that mounts in front of the radiator...I have used these on several other vehicles.

Is this a waste of time and money and potentially dangerous to the tranny?????

 

No... an additional cooler is fine. The cooler is free-flowing enough that it won't affect the bypass valve.

What was originally being discussed was an external filter plumbed into the cooler lines. The filter would possibly have too much fluid-resistance, especially as the filter got dirty. The oil cooler bypass valve would then bypass the cooler and the transmission could overheat.

This is all in-theory... I'm hoping someone still tries it and plumbs a pressure gauge into the pressure line so we can all learn if it will work or not.

 

you are gonna still use the stock in radiator cooler?

 

I left mine in the loop. I thought that the more cooling the better.

 

Yep...the plan was to add the cooler in series to the factory setup....I want to add the cooler to the line coming from the radiator cooler...anyone know which line that is??

 

nice idea

 

Is there a picture or diagram of this system that can be posted? If this is the case and can be verified, I will remove my thermo bypass and just go directly to the cooler.

 

I looked online... no luck.

The best I could do was take a picture of our service manual fluid diagram.

 

I like the idea of adding a External cooler but i wonder if adding one ontop of the internal would be worth it??

 

well since mine allready has a factory tranny cooler im gonna replace it while im doin my rad with a better one, now onto my question, what kinda pressure guage are we talkin about plumbing inline? are we talkin auto meter style or are we talkin http://www.automotivetools4less.com/...c0ef1059c0abdc that kind? if its the second how would i plumb that in and still be able to drive or would i?

 

bump

 

I used a B&M gauge and mounted it in a Autometer A-piller gauge pod.

 

yeah i got the trans temp down im just wondering bout the tranny psi

 

Cool, thanks for the pic. Was this in the FSM or something else?
