what’s up guys. So I have been having an O/D issue for a while now. Sometimes upon startup the car will not not be in overdrive and start in 2nd gear and never hit 4th gear so I have to restart it and turn it back on. Happens almost everyday. But I have also noticed (when O/D does work) alight slipping from 1st to 2nd gear. But don’t want to keep it auto (4spees auto sucks). Really want to swap it to manual but don’t know where to search for parts. Any ideas how to source everything? And help would be appreciated.
