This study is focused on driving with manual or automatic transmissions in City with heavy traffic. Generally, it aimed to compare the manual transmission with the automatic transmission of an automobile. Specifically, it sought to determine the extent of the difference on the effectiveness between the two transmissions as perceived by the respondents and their significant difference. Observation and checklist questionnaire coupled with interview was used to gather the data using convenience sampling whereby only the owners and/or drivers with automobiles with manual and automatic transmissions driving in Vigan City were taken as the respondents. Based from the findings, there is a significant difference between manual and automatic transmissions of an automobile in city driving, whereby, the latter transmission is better on “driving comfort” while the former is better on “utility”, “fuel consumption”, and “service and maintenance”. It is then recommended that the extent of difference on the effectiveness between the manual and automatic transmissions of an automobile should be disseminated to inform auto mechanic students as part of their learning and guide the prospective buyers and users on what transmission of an automobile to prefer. Also, automobile companies must keep on improving the technology on the effectiveness of automobiles pertaining on their transmissions.
