Shifting Problem

[xi Talon ix]

I took my car out lastnight for the first time since I changed the clutch. I have a 1990 Talon TSI AWD to let ya know. But anywho, I was driving and I would be going fine until I had to slow down becuase of a speed bump. When I slowed to go over the speed bump the car would shut off but all the lights and everything would still be on, all dash lights, head lights. everything of the sort. also, it was kinda making me mad becuase it shut off everytime that I slowed down so I stomped the gas and ran it up to like 5500 rpms and went for second and it grinded really bad. then that got me confused. it was like everytime that I got the rpm's up it wouldn't shift into the next gear. im pretty upset guys, need some help.

Sounds like two different problems that aren't related. For the car turning off, check to make sure your battery connections are secure. Also check to make sure all connections to sensors like the mas, cas, injectors are secure.

The shifting problem sounds like a clutch not disengaging. A good test to find out if this is true is put the car in first gear, keep the clutch all the way down and with the car stationary, starting increasing the revs. If the car starts to creep forward with the clutch all the way in, that means your clutch is not disengaging all the way. Possible reasons could be a worn out clutch pedal assembly, leaking master cylinder, leaking slave cylinder, improperly bled clutch, or any combination of these.

For the slave, pull the boot back on it and verify there is no fluid coming out. For the master, verify you don't have fluid leaking where the master comes through the firewall under the dash. For the pedal assembly, check to see if there is excessive freeplay before it starts pushing on the master cylinder. Let us know what you find.

You say that the clutch might not be disengaging. But if that were it then I wouldn't be able to shift into any gear then right? Because I can shift into any gear when the rpm's are low like a normal shift. I'm confused.

If it wasn't disengaging at all, then yes, you wouldn't be able to shift into any gear. Usually the problems I mentioned below don't cause the clutch to not disengage, but rather reduce the throw of the clutch fork making the clutch not disengage as much. Big difference. Combined with the forced of a spinning clutch, the reduced throw can cause the clutch to partially engage at higher rpms.

If you do the test I mentioned, the car will probably creep forward slightly, which means it's partially engaging at that point. Hopefully this makes sense. If it doesn't creep forward, then there is a problem with the synchros in the tranny.

You can adjust the shifter cables, I think on 2nd gear it is the side to side cable. They are under you gear shifter
