This is what the letter says:
American Honda is announcing a warranty extension for the automatic transmission on all 2000-01 Accords, Odysseys, and Preludes. The automatic transmission and torque converter are now covered for a total of 7 years or 100,000 miles, whichever occurs first, from the date of original sale. We are providing this warranty extension because a higher than normal number of automatic transmissions in certain vehicles may have problems due to defects in material or workmanship beyond the 3-year, 36,000-mile new vehicle limited warranty.
