I have a 97 Mitsubishi Eclipse GS-T and was wondering if anyone knows the solution to my car problem. Recently, my clutch peddle was leaking brake fluid and was completely soft when stepped on. So I found out it was the clutch master cylinder and had that replaced. However, my gears starts to slip whenever my engine gets hot or is driven for about 30 to 45 min nonstop. Pissed about the gear slipping, I recently had the clutch replaced with a whole new clutch kit. Everything was installed correctlly; however, I still get the gear slippage after the engine gets hot for about 30 minutes. Gears go into perfectly and shift perfectly when the engine is first started, but after the engine warms up, I can still go into gear but the engine just revs up when I step on the gas while leveling with the clutch. In addition, the clutch peddle gets stiffer and stiffer as the engine gets hot, eventually, slipping crazily (goes into gear and out of gear but revs as step on gas). I also adjusted the gear peddle many times, buying me some time before the peddle gets stiff, but this is not how it is supposed to be. I don't wanna spend more money than I should because I was hoping to bring it in to the shop again, so if anyone got answers, that'll be great!
