What are some possible causes\solutions regarding 1997 Infiniti I30 manual transmission problems? I.E. Will not shift gears most of the time sometimes I have to kill the engine and put in in gear and start again this problem came suddenly parked vehicle. Their is a lot of play in the clutch. When I start the vihicle in neutral and try to put in first it will not shift can put in 1st when vehicle is not running gears will not shift properly about 85% of the time this problem litterally happened over night. Also when driving for example in 5th gear when I try to downshift it doesn't seem to want to disengage other gears to a lesser extent most issue is 5th gear

If the clutch pedal is ow, most probably the hydraulic system is faulty and you need to have a look at the master or slave cylinder.

There seems to be a leak underneath but I cannot tell where it is coming from it doesn't appear to be oil it drove perfect the other day when I parked it the next morning is when the problem popped up could those systems you listed before go bad that quickly?

They usually don't fail immediately but when leaks occur, fluid level would go down and air would get into the system resulting in low pedal height.

Check the fluid level and if it is low, top it up and pump the pedal a few times. If it does not response, try bleeding the system. This is only a temporary measure as you need to get the leak rectified, which should be from the slave cylinder if it is at transmission side.

If that is the problem, it is best to get the master cylinder repaired/replaced as well as it should be on its way out soon.

I will definitely give that a try first to replace the master slave cylinder is that a costly repair

The slave cylinder is not too expensive ut the master cylinder would cost more. I am not too sure about the costing around your area so it is best to ask around for the going prices.

Have yuo chhecked the fluid level? You need to top it up if it is low as further depletion would result in no clutch pressure at all.
