It's possibly a 10/100 item, but probably not. For it to be a 10/100 item,
it would pretty much need to be an internal trans issue or a defect in one
of the engine/trans mounts. I can't think of any other possible causes
for this condition that the 10/100 warranty would cover.
Transmission sensors (vehicle speed sensor, input speed sensor, output
speed sensor, range switch, etc.) are not considered to be powertrain
parts and are not covered by the 10/100 warranty.
