Will not go into gear(manual)

You may have an internal transmission problem or clutch issue. If you can shift the car into gear while running without using the clutch pedal, suspect a defective clutch

it may have air or link(s). check clutch system.

If you put the trans in neutral and depress the clutch pedal it should still start.
The clutch is hydraulic, so there should be something connecting the pedal to the master cyl and the slave cyl to the clutch disk.

a clutch can last from a week(little old lady resting her foot on the pedal) to about 150k.it aint a problem with the car.....a previous owner perhaps........we used to sell ex rentals and 70% of the clutches were f....d.

needs a bleed,or lazy mans way -- put a brick on the clutch pedal overnight and see if the air rises up and out of system

check fluid levels or for air in the lines if so bleed or your clutch plate or pressure plate are gone

A clutch issue youtend to have more of an engagement problem with 1st and reverse gear for a small time period before you notice other gears.You want to check the clutch hydrolic system for any leaks(clutch slave at transmission,clutch master,which you look for leakage on interior above clutch pedal)and at fluid resevoir.you also want to double check condition of trans fluid. strongly recommend using only HONDA BRAND MANUAL TRANS. FLUID when doing maintinance,fluid should be replaced every 30k on this car.The Honda brand fluid is like night and day on these cars,it WILL make a difference in shifting!!TRust Me on this point! Sorry now back to your main clutch issue,when driveing and you go to shift gears and normally notice grinding,with clutch pedal in shft out of gear and before engageing it into next gear do a double pump of clutch pedal then see if when continuing to next gear if it engagees smoother.if so you know you have without a dout a clutch pressure plate/disc problem. I can tell you that in twenty years the only manual transmissions themselves that ever had problems were due to outside influences(gear oil in transmission,improper driveing,etc.)let me know what you find and we can go from there..JOEL

Have your mechanic ck for a possible issue with the pilot bearing. if the clutch linkage is indeed full travel, then the clutch should be "disengaged" and the only thing left is a pilot bearing (which should be replaced at every clutch replacement) or there is a problem with the disc. If clutches dont last 100k miles it either the driver or cheap parts.

clutch needing replaced, very common on all manuals

pedal travel adjustment,yes
gear shift adjustment,no

When you bleed the system make sure to bleed in 2 points.
One is the slave cylinder, the other one is in the joint of the line (hydraulic line) when it passes from the chassis to the engine (right above the transmission). loosen the bolt just a little and press the clutch again (several times).
then you will be done bleeding the system correctly and your clutch will work again!
