First I started to have a loud rattling sound when I am idling, neutral with the clutch out. I was told it was normal wear noise, but I could replace the throw out bearing to make it quieter. After it was replaced I started hearing a loud whistling sound when my Jeep is coasting and above 2000 rpms with the clutch out. The dealership keeps telling me it's normal. I have taken it back 2 times, but they can't find the problem. I'm still having the noise and there is no sign of a fix from the dealership. They just keep saying it's normal. Just like everything else they have had to fix!!!.
Three month old Jeep Wrangler with 6 speed. After vehicle has been sitting for a few hours, regardless of outside temperature, the first several 1-2 shifts upon driving it again exhibit a loud grinding sound which can also be felt through the shifter. The transmission is reluctant to come out of first gear. It has to be pulled out of gear instead of just sliding out. It then feels like it bounces off of second gear, requiring another attempt to engage second. When I first got the vehicle, it actually felt like there was no fluid in the transmission. Shifting becomes much smoother, I. E. Normal, once it has been run for a few miles, although I do feel it occasionally even after driving for a while. Dealer road tested the vehicle and says it is "o. K. At this time. " this condition may have some safety ramifications in addition to the transmission longevity issues. First gear in this vehicle is very low. I only use it to start rolling a little bit and then quickly try to engage second. However, I am so conscious of the difficulty of this 1-2 shift that I execute it very slowly, all the while cringing at he thought of the damage I am doing to the transmission. The problem is that the rpm's drop off so much during the time of this shift that there is little power available once I actually engage second, resulting in leisurely acceleration at best. On two occasions already, the people behind me have blown their horns and nearly run up my back because, I believe, they must have thought I was going to stop instead of continuing to accelerate. It is getting to the point where, if the road is level, I take off using second gear instead of first until I have traveled several miles and the transmission begins to behave normally. I have driven manual transmissions for 20 years and have never experienced this type of behavior.
