You can't remove the stock sender, besides powering the warning light it also senses the temp so your trans can kick into OD after it warms up or out if it overheats. Check the archives for much info on installing an AT temp sender, many folks replace the output line to the cooler with one from a '95, they have a port for the sender built in.
