One problem related to manual transmission has been reported for the 1999 Ford F-450. The most recently reported issues are listed below.
6 speed manual transmission replaced under waranty at 29,600 miles the first time. Failed, and would cost more to rebuild so it was replaced again at 88,260 miles at my exspense totalling $3,632. 00. Ford would not make any after warranty assitance. Have heard this transmission is weak. Can u help me to get Ford to reimberce for the cost of this second transmission??.
