Dacco makes the Banks Billet torque converter. You can go to daccoinc.com and learn more about other Dacco branded converters.

I don't know who manufacturers the BD torque converter (not likely BD).

Other brand names of torque converters include Valair, Suncoast, and ATS. Of these three, I do not know the actual manufacturer either.

Then there is Precision Industries, out of Tennessee. These are the purple painted billet torque converters that BTS (Brian's Truck Shop... famous for bullet proofing Ford automatics and guaranteeing them for life) uses in his builds. Precision apparently manufacturers their own product.

Then there is Ford. Not a bad idea to go OEM, especially if any of your 5 yr / 100K is left on your engine warranty. Even if there is only 5 months left, repairs on the 6.4L typically run north of $10K, so if an aftermarket torque converter can be pointed to as an even remotely possible cause for non-Ford designed stress on the engine, it would best be avoided.

Finally, investing a lot of money in high end drivetrain parts on a 6.4L with 76K miles is a questionable endeavor. You are just about at the magic mileage mark where many owners reported problems with this motor. At some point, a cost benefit analysis will run out of legs in favor of keeping your 2008, that for some folks became a black hole that gobbled up their replacement truck spending budget because they spent so much fixing the lost cause that they had.

This all points toward sticking with a stock replacement converter, or Ford's "HD" version of the same, if offered for your version of transmission.

Funny you say its not worth fixing with78K, my ford mech had an identical 08 f250 6.4 in his bay with 262K with original motor and tranny but TC had been replaced. so the ford version is not an option it will be aftermarket just not sure whichone yet.
