No speedometer when cold, flashing S4

Hello all, new Prelude owner,
1990 auto SI 2.1 engine, no modifications.
I'm reading a code 17 out of the vcm and just four flashing codes on the transmission module?
I know 17 is the speed sensor or a connection so I removed and tested. Zero ohms with no magnet and 105 near the magnet, so what number should I see?
Before checking the sensor it would shift a little rough between 1st & 2nd and a fairly hard down shift when turning corners. Since checking sensor, problem changed and now it shifts at 4000 rpm or you can let off the gas it and shifts. Could I have damaged the sensor by getting the magnet to close?
