I've got a newly rebuilt trans and a BTS valve body on the way. I'm wanting to upgrade my torque converter as well. Of course Brian recommends the PI and has no opinions on any other alternatives. As much as I would love to have a PI, the $1200 is a hard pill to swallow. I've searched on here and most posts are 4 or 5 years old. Just looking for some fresh opinions on converters. I tow around 8500 pounds in the summer months and don't see my HP ever exceeding the 400 mark. This is for the F350 in my sig.
