Hey guys I own a 1998 240 and I have a problem I can't figure out. I have a KA24DE with 170k and full mobile 1 synthetic changes. So ill start from the beginning...

A couple weeks ago my clutch started to slip so I obviously replaced my clutch and while I was at it got myself an aluminum flywheel. After replacing it my pedal stuck to the floor. I bled and still nothing. Replaced the clutch master and slave cylinder. Also I had no leaks. This popped the pedal up a bit but its crazy spongy. Now here's my problem. I can't put my trams into first when the car is on, and reverse also. I have to stop the car put it into gear and go from there. It also grinds sometimes when shifting into 2nd and 3rd.

-very spongy clutch pedal that won't go up 100%
-I have to force or turn the car off to put it in first.

So the Only things I can think of that can cause this is a worn pilot bearing, bad synchros, I didn't bleed the lines correctly, or the clutch isn't engaging all the way due to a bad fork and/or throw out bearing. Help me out guys! Your the experts!

just had a very similar problem. the clutch dampener has a bleed needle on it as well. So you'll need to bleed that also... or do what I did and remove it. Just bend the line to go into the slave. I couldn't tell a difference at all and after bleeding it my pedal feels great now.

Reason you cant get it into gear is because your clutch isn't fully depressed. Measure the movement in your slave. Mine went from a little under a 1/2 inch to a little over 5/8th's after removing the dampener.

This prob is your problem (bleeding dampener) but why didn't you replace the pilot barring when you replaced the clutch? if you need to(after bleeding), you can also adjust your clutch pedal up or down by detaching and turning the fork connected to your pedal
