transmission error codes

[bdgst14]

My 98 Tiburon FX has had the check engine light on for almost two weeks now...I brought it to the dealer thinking it was a sensor or spark plugs or something, since it only slightly hesitates when switching gears...the codes the mechanic gave me were P1709 and P0747--he said one was for a kick-down sensor and the other for a PCSV--I was wondering if anybody thought either of these was worth fixing--the mechanic suggested that instead of making these repairs I just ride the transmission out and then replace the whole thing.
