Kinda hard to say.Were any upgrades done to the trans?Did you reset the psom when you went to bigger tires?I put bigger tires on mine and the trans.labored and lugged instead of shifting when it should have.

If the computer was never 'told' what size tires were put on it, it's going to do all of its calculations assuming it has the same size tires it came with originally. Since your new tires are larger than stock, it will be slightly off as far as your MPH, odometer, and your shift points. You can get the exact difference on this page:

Your new tires mean you're actually going a little bit faster than your speedo says, and slightly fewer miles than your odometer indicates. Also your tranny will be shifting at the wrong times. If it was a manual tranny, it wouldn't matter at all.

33..12.50..16.5, that tire size is only wider than stock, it is the same diameter (or very close) to the stock tire.
My 88 F250 stock tire per door sticker is LT255/85R16 which is a 33-1/2" tire,
Its not likely the tires causing the Tranny problems.
You should have posted the problems you were having, could have been something easier than you thought, modulator, torque converter, band adjustment?? A tranny shop will fix it but they will probably not show you the bad parts or offer an explanation as to why it failed, you really need to know that above all.

Most of the time, tires wont harm anything, except if you have different sizes of tires on each axle sorta deal. The tranny might labour a little bit more at the shift points, but I dont think it would be enough to harm it much!
