I am swapping a 518 OD in to replace a manual, and bought a 14,400 BTU B&M SuperCooler, but it uses 5/16" hose barbs. Is this going to be a problem? I have read 3/8" lines are important on the 518.
If the 518 needs the flow of the 3/8" lines, then this could be a problem. But if the 3/8" line is more to deal with the inefficiency of the stock, radiator based cooler, will the more efficient B&M cooler be fine with the 5/16" inlets? I can even run 3/8" to the cooler, bought a 20' roll of tube already.
For what it is worth, I have already added a deeper aluminum pan and a Autometer trans temp gauge sender into the pan. So I will know if there is a heat problem, but i would rather head it off, than fix it later.

I had the same concerned when I swapped a 518 into my 87 Ram. It was replacing a 904 which, just like your car, had 5/16" lines and fittings into the cooler.
Raised the concern to my transmission guy. He couldn't advise me either way so he wanted to put a number on it.
Pulled the truck into his shop and disconnected my transmission lines. He then connected them up to his machine which measured the flow. Today I do not recall the number but he was more than satified with the Gallons/minute his machine was flowing through my cooler set up so he gave it his passing grade.
It was steel 5/16" lines into the factory radiator cooler. Rubber lines into a B&M stacked plate cooler. Back to steel lines, return to transmission.

If that machine has more output than the pump in a torqueflite then the results aren't necessarily accurate. If a 5/16 hydraulic circuit has too many pressure drops for the 3/8 application, but a larger pump is installed for testing purposes, then the flowrate of the circuit could be mistakenly seen to be enough. There are a lot of variables here, though -- just food4though.

I've always been a little leary of bypassing a radiator cooler (which works by conduction) to use only a liquid-to-air cooler (works by less-effective convection). And keep in mind that the hottest oil temps will be coming out of the converter, so putting a temp sender at the end of the line, into a deeper pan with more fluid capacity, might end up as a buffer that could reduce your warning time for any temperature problems.
OTH, if you are running a low-stall converter maybe there's nothing to worry about.
Parts I seek:
driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set
16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better.
69-73 C-body caliper brackets and/or splashields
Send a PM.
