1 • Test Support - Grand National Cars

The Plymouth was prepared with an automatic transmission for testing
. at Huntsville.

Tests began on 13 July with the B&M experimental transmission modi­
fied with a swinging oil pick up and cooler lines set up to run with and
without a filter.

The transmission failed and was returned to B&M for inspection. A
C Q
second transmission with standard gear ratios was installed and w -
run for durability. Low oil pressure on turns was indicated and a
deep sump transmission pan was installed. The deep pan bottomed
' out on several areas of the course, lost oil pressure, and failed the
transmission.
