New Trans cooler = checking fluid level ?

Plan on installing new transmission cooler (Earls) in series with in-radiator stock cooler and since we don't have a dipstick, I was planning on filling the cooler with fluid before hooking up the braided lines (I am using AN fittings). Anyone see an issue with this ? Maybe a little more for amount in lines ?

Is there some way to purchase a dipstick from DCX ?

thanks,
Dave

I installed a transmission cooler on mine in series. Check out my writeup on the LX forum for pics and details

Thanks to both for replies ! Sunnysrt8, I see you used the LX forums grocery list from Summit, as I did. So, did you run the braided lines back to where it transitions to rubber and cut there ? do you use the barb fitting to go into the rubber ?

so, confirm please:

What is the flow ? i.e is the front line in the trans the return or feed ?

could you just tell me how you ran the lines ? i.e. front line is feed OUT of trans,then into new cooler, out of new cooler, into top of stock cooler out of bottom of stock cooler, then back to rear trans line ?

I am going to do the long threaded rod mount, going through the bottom and top holes into the bumper.

THANKS for the great pictures !

Dave

Mango:
if we get the Borla on in time, this Friday night.

Learned alot about transmissions and fluid temps from last vehicle I had. Anything over 200 degrees sustained is not good. Monitoring this vehicle with Dashhawk has shown me there are peaks over 200 degrees, with most daily driving being in the 150-170 range, which is OK. 180 thermo helped lower, as did fan mod, but I noticed the sloppiness in transmission when temps were higher.
