Re: Po732 and po734 codes
I'd assume that you would have more problems with a broken band. The filter still remains in question. If you've had the fluid changed, or you bought it used, often a fluid change is done by pumping out the old and pouring the new in. The filter never gets looked at or changed. Given the price of a transmission, it's probably worth the price/hassle of draining it, dropping the pan and changing the filter.
