[sdiy] Thermistor == tempco ??

[Harry Bissell Jr]

DigiKey

PANASONIC Metal Film Thermosensitive Chip Resistors

There are three wattages, I'd suggest the 0805
(1/10W) part. Get the +3300  in the value you want.

These are SMT resistors. You'd have to solder leads
to them, and glue them to the tranny.

Or check MicroOhm, KRL-Bantry, or Vishay Ultronix.

Prepare to pay through the nose. I'd suggest you buy
100pcs from MicroOhm and sell the ones you don't need
to other DIYers. They would be about $1.25 each in
100s. They stock 1Kohm 5% +3300
