2001 F250 PSD Tranny Build Date Question

[montanafos]

I just purchased a very clean '01 F250 Crew Cab PSD. Love the truck and have become familiar with the diode transmission problem with this model year. Upon looking up the TSB on the internet I see build dates between 7/2000 and 3/23/01 are at those affected. My truck gas a build date of 3/8/01. Does this automatically mean I am at risk and if so, any suggestions? Truck seems to run and shift perfectly at thi spoint. Appreciate your input.
