Shows how I did mine bypassing the cooler in the radiator.

FWIW...I ran braided lines to/from my external B&M trans cooler using -6AN lines. I chose this route to avoid the constant leaks I was experiencing from splicing hard steel lines. I know the braided hose is not necessary for the pressures. However, this way I don't have to worry about leaks every time the transmission comes out for freshening. Plus, its relatively cheap if you already have some braided hose lying around from other projects (i.e. fuel lines). Just my opinion
I have tested several trans and converters with hoses to the coolers.
The system I used that worked for me on a pretty much stock engine and 200 4R was Parker 801-Plus (-6 size) with push lok fittings. I used radiator clamps to additionally secure the hose to the fittings. Required by some sanctioning bodies.
The reason for my post is to caution users to know what your trans out to cooler pressures and temps are.
On a 820 rwhp, 3950# car, PI 3400 measured stall, 5-disc converter, 200 4R, in tank OEM cooler; I logged 125psi out pressure and a max oil temp of 245*F and 2.2 gpm at the strip. 801-Plus hose is near this as max specs go. Logging was pressure transducers, thermocouples and electro-magnetic flow meter. The trans was a highly modified full manual unit. On the 801-Plus look for flexibility and color change. Note that the SS braided hose has higher specs than the 801.
On my pro mod, glide trans car. I found the SS braided trans out hose had melted the braid impression into a plastic hose bracket. I put the instrumentation on the car; the results were a surprise. The converter builder was also surprised. The pressure out was 150 psi and 340*F oil to the coolers. I now use AN-8 teflon lined SS braided hose to the coolers, and SS braided on the return. Most suppliers have these products.
Another good reason to use synthetic fluids.
I changed converter builders; now, I have 290*F output oil temp. Also quicker.

The 200 4R are usually 1/4" NPT. Some are a port thread and you can carefully thread a 1/4 NPT into it. The AN -8 can be used on the 200 4R. I have not measured the effect vs AN -6. I don't believe AN -8 would be necessary. Wouldn't hurt anything.
On the 200 4R, use a 45* 1/4" adapter fitting. Jegs #555-100124 is 1/4 NPT to AN -6. Jegs #555-100125 is 1/4 NPT to AN -8. Both are male 45*; point out towards the right front fender. Insulate the hose if it is near your exhaust. Hose wraps are common items.

When I did mine, I used -10 line. Its pretty big. The lines, cooler itself; and bigger oil filter added over a 1 quart increase in capacity to my car!
Going to redo it again soon. Just gonna modify whats there and trim the lines some.
Also got some -6 for the trans lines.
Anybody know what the thread size is in the 200 case for the cooler lines?
