PATC 2800 torque converter
I recently installed a PATC 2800 stall torque converter on my 2wd 2001 Ram extended cab with a 5.2 liter engine.
Trans fluid temps stayed about the same (160* cruising) as well as cruising RPM (2000 at 70 on a 30" tall, 255/70/16 tire) between the two converters. My truck also has a factory external cooler.
The truck saw about a 5-hundredth improvement in 60' time, but ultimately ran the same 1/4 mile time as before I believe due to worse air. I cannot verify this because I didn't take air readings between the two runs, but I know the air was hot and muggy Friday night. The truck was run at operating temperature on both passes and the only mods are an electric fan and 26-inch tall "track" Street tires mounted on steel spare wheels.
Bonus tip: the 26" tires look incredibly goofy, but are worth about 3-tenths in quarter mile time. Total investment was $100 between buying the tires, buying an extra spare wheel, and mount/balance. They equate to about a 4.10 gear with 30" tires.
I hope this helps someone contemplating buying a little higher stall converter. To me, it was worth it; but don't expect to feel a seat-of-your-pants difference in how it accelerates. After all, the $315 converter is only a reworked stock converter. Below is a video; first video is stock, second is with the PATC converter. It only saw about a 500rpm difference in flash, but it's still better than stock.
