I used synthetic valvoline b/c my mechanic gets a big discount on the stuff and its awful. I've heard good things about Mobil1 Syn and Amsoil Syn so i'll be switching to either pretty soon.
I have just done my change and used Pennzoil Synchromesh....works really good for me, got rid of all grinding I had going from 5:th to 3:rd...love the stuff!
Royal purple synchromesh has a good reputation but i havn't tested it myself...
i went to pepboys the other day and said that there is automatic transmission fluid in all celica's transmissions. the guy told me not to pt gear oil in and to go to the dealership.
