look up any word, like sex:
the belief and/or complex that one is more superior than others simply due to the transmission of his/her car.

Usually found amongst dumbasses who recently acquired a car of manual transmission.

Common symptoms-
1. thinking anybody gives a shit that their car is manual
2. discussing transmission of cars more often than the common once every 3 years
3. down syndrome

Possible cures/treatments-
1. Exchanging manual transmission car for automatic
2. Realizing one is retarded and never mentioning his/her transmission nor the transmission of others ever again
3. Suicide
Goth's transmissionism is really ruining his social life...he feels that driving a stick shift makes him more of a man/real driver.
