Figured I would show my setup for anyone looking for a nice "budget" transmission cooler setup on a 4l60 in the front of a Fbody , total came out to about $185 bucks.
The Trucool H7B is the exact same as the B&M 70274 at almost half the cost (both are made by Long in Mexico) .
For anyone worried about the "Jegs" brand fittings and lines.. I personally havent had and problems with leaking or anything like that, also keep in mind Jegs brand products are not made in house they are just rebranded products.

However, I unfortunately have negative imformation to provide... I wish I didn't, but I do.
I have had nothing but very poor experiences with aluminum -AN fittings from Jeg's/ Summit Racing.
In my own experience; I would highly recommend to all of you that a "Name Brand" be purchased and used for aluminum -AN fittings.
Steel -AN fittings from Jeg's/ Summit Racing are fine.
I have found that the Jeg's/ Summit Racing aluminum -AN fittings strip-out or become very easily damaged if they are unscrewed/ disconnected from one another after the first time installing the fittings.
For example:
-When removing a automatic transmission cooler line -AN hose-end fitting from the fittings installed into the transmission of cooler...
that the threads strip-out, or fall apart, or become damaged enough that reconnecting the cooler line to the transmission or cooler is not possible.
Should you guys plan to purchase and use these fittings from Jeg's or Summit Racing... I would install them once and never touch them again.
Simply disconnecting a hose-end from a fitting could be the end... Thus making the -AN fittings complete garbage.
I hope you guys do not experience this... But I have on too many occasions to be able to recommend the products.
Also Using a thread lubricant, or anit-seize on these fittings in general can help them last much longer...
Also be very careful to not over tighten the fittings, as that can ruin them as well.
11 second club, you must either have a manual transmission or an automatic with no temperature gauge.
I'm asking because I'm building a drag strip car and plan on running a Powerglide. I do have a manual and its been high 11's on motor with me being easy on it. Pretty respectable for a 3600lb street car with an LSX, S60 and full KOOKS 3 inch exhaust!
My th350 did fine all last season on the street, cruising to the beach and on the strip through the stock cooler, and I have a temp gauge and it never got hot....
Do they make the 1/4 NPSM to -6AN fitting in a 90 deg elbow? I ask because of fitment concerns with the 4L80E in a 4th gen fbody.
Is one perfectly fine using the connection angles seen in the image above or is it very tight even with hammering the tunnel?
For example, a 90* -AN fitting actually can hinder the flow of the fluid passing through it (depending on flow rates and pressures).
The fluid actually hits a wall and gets forced sideways when passing through the fitting.
The inside of this fitting is just a sharp corner and creates an obstruction for the fluid inside.
On the other hand; when using a straight fitting with a hose end that has a 90* turn...
The fluid now passing through has a nice curve to follow through the tubing that the hose end is made of.
There is no "Wall" to hit in this configuration.

I almost over looked this...
Late 4L80E transmissions with the cooler circuit ports that are one in front and one towards the center of the case... require special fittings for use with -AN lines.
The cooler port towards the center of the case actually has to go through the case and make it to the center support.
Should a normal -AN fitting be used... the transmission will have a huge internal cross-leak.
Not Good!
Make sure to purchase 4L80E specific -AN fittings, like pictured above.
