Hey well ive had my celica for about a month and the tranny has been great and then all of a sudden yesterday I pulled to a stop sign and tried to put it into first but it wouldn't let me shift into first and to get it into first i had to do a rolling start to get it into gear. When i Shifted up to second or third it grinded up the gears when i shifted.
Anyone know whats wrong and what i need to do to fix it?
Thx Jacob

Check your gear oil level

Worse comes to worse your synchro rings are going going gone

basics,

mileage? clutch,

slave cylinder,

check the levels.
