Get this and you should be good. It increases the line pressure and gets rid of the shuttle shift.

Why not save up for trans work/replacement?

You can smoke a tranny on stock tune with that said run it control your foot till you can upgrade the tranny! It's a good all around improvement!

I do plan on upgrading the tranny, but would like to know what will run well with the truck and the tranny for the time being.

It took about 2 years/20k miles to fry my 48RE with a Smarty Jr., if that's what you mean.

That's with the SK48RE shift kit installed, as well.
