    I am posting this here for Pamela.

    Hi. I have a Ford Ranger 2006, 5 speed, manual transmission. For a while now I have noticed that my car has low acceleration even though it reaches high RPMs. Engine revvs and so it produces loud sounds too. For example, car reaches 20KPH and RPM pumps up to 2. I have visited a mechanic and advised that the air filter be replaced. That being said, I have replaced the air filter but there’s still no change in the car’s performance. I did a bit of research and came across clutch slipping. With this, I have had my mechanic replace my clutch disc, anticipating that after doing so, my car would run smooth again. But after replacing the clutch disc, still no change in my RPM/acceleration concerns. It’s getting frustrating now. I really hope you could help me on this one. Thanks a lot!

    I’ve been doing some thinking about your problem and I was wondering about something. Did you replace the throw-out bearing when you replaced the clutch disc? The reason I suggest this is that if you have been riding the clutch, as many drivers do, even if they don’t think about it, you are putting huge amounts of wear on the throw-out bearing so that even if you replace the clutch disc you are still going to have problems from the bearing.

    The throw-out bearing is a necessary part of any manual transmission because it is the device on which activates the process that separates the clutch disc and deactivates the transmission momentarily so that you can flick to the next gear and then get of the clutch.

    My suggestion here is having your technician take a close look at the bearing and replace it. I think it will solve your problem.
