recently my tranny has been actin up, its been super hard to get in and out of gear, i mean ya got use two hands and really push, well this mornin i put the clutch in and went to shift from 1st to reverse, and all i heard was the gear grindin then a bad clunk and it dropped into reverse. does the clutch need adjusting? or does the tranny need to get flushed and refilled. itll grind also if i downshift into 1st at like 6mph itll grand like a siv. thanks any help is appreciated.
