Hi! I was wondering if anyone could help me with this.

I drive a Nissan 240SX SE model, 1992. I recently failed inspection for a bunch of things (exaust & calipers). I know a trustworth mechanic to take my car to and so there I go. I knew I needed a new clutch, so I did all three in one big go. Excellent, right? So after I get the car back, I drive it around and then I begin to notice that the clutch was slipping. It didn't slip when I first started to drive the car - only after I had driven it for a while. I tested it out for a few days and the results were the same. I returned it to my mechanic and he replaced the clutch again. Says it was a faulty pressure plate.

Two days later, the brand-new clutch is slipping, in the same way. After I drive for a while, the clutch slips. I have since consulted with my mechanic and everything looks good: new master and slave cylinders, the fork assembly is operating fine, the system is bled. If anyone can help me figure this out, I'd greatly apprecite it.

Thanks!

that's really strange, when i got my new clutch it was super grabby for a few weeks. your pedal probably just needs to be adjusted. if not i would machine the flywheel just to be safe and make sure my mechanic was doing the right job.

Did you break it in properly? no burn outs/7,000rpm driving etc..
You might have glazed the clutch.

Hows your flywheel?

The slipping happens at low RPMs, I haven't beat on the car, maybe hit 6000 a few times on the highway. The flywheel was resurfaced and checkedfor flatness. If I had glazed the clutch, wouldn't it slip all the time instead of after 20 minutes of driving?

clutch kit usually comes with disk, pressure plate and the throw-out bearing. The bearing looks insignificant but will allow the pressure plate to move in/out which is necessary. hope your mechanic replaced that as well because it will wear out

try adjusting. also, maybe rear main is leaking? if oil got on the clutch disc then that would cause slipping...
