Is it worth getting speed sensor inside transmission repaired?

Hi Goodguysdiesel, I've asked if they are sure that will fix the problem and I got the typical evasive answer. They gave me an estimate and the parts are less than $300, the rest is labour. They do repairs based on a fixed price, not hourly. I've had all sorts of weird repairs to do with this car: bearings at 50,000 mi (!!!!), broken suspension coil, now the speedometer. They told me this has never been reported in the Toyota repairs database.
