94 honda accord ex

manual trans

trans went out about 90 days ago and replaced with a junkyard trans.

when replacing the tranny I replaced the clutch and pressure plate but the flywheel looked good and at the time was out of the budget.

90 days it ran like a charm till one morning it slipped for about 2 seconds then it caught but by the time I went another 100 yds or so I had no gears.

Had it towed back to the house it had gears again but tried to run it up and down the driveway it lost the gears again so I research it and if it slips its the clutch so replaced the clutch and pressure plate also the flywheel got it all back together and it drove about 1/4 mile and lost the gears again so now I'm thinking that its the linkage so I by hand put the shift levers into 1st gear hoping to get it into garage but its still in neutral

any help is greatly appreciated
