1990 300zx tranny help!!
 

hello i have a 1990 300zx non-turbo, auto and i was wondering how difficult it would be to do a 5 sp conversion on this car? and if its worth the trouble. see my car has a super long shift time from first to second and when i come to a stop it doesnt seem to get out of gear, like its always straining the brakes! maybe i need a new converter? any tips will help!! thanks!!
