Two problems related to transmission shudder have been reported for the 1997 Ford Mustang. The most recently reported issues are listed below.
The transmission has been replaced because it pops out of gear when driving at 55 mph. The transmission also grinds when shifting and this causes the vehicle to slow down.
Transmission grinds going into 2nd gear and pops out of reverse almost all cobra owners I have talked with has these problems with the t-45 transmission dealer can't reproduce the problem so no fix is possible.
