Problem #1… 2006 Jeep Wrangler Unlimited Rubicon…I purchased it December 2011 with about 50,000 miles. It has a flood title as it appears to have suffered some water damage a couple months prior to me aquiring it. The Jeep came from the Massachusetts area and it is living in Iowa now. I believe the water was all the way up to the rear view mirror because it has water damage spots in it. A few weeks after I purchased it I began to notice a grinding when I shifted from 1st to 2nd and from 3rd to 4th. I took it back to the dealer and they ended up replacing the clutch and flushing the transmission fluid. That seemed to fix it for a few months but then it came back. Also, if I keep the clutch pressed in for about 1 second or 2 and then shift it into gear it doesn’t seem to grind, but with a newly replaced clutch and just over 50,000 miles I don’t feel like I should have to do that. Currently I have about 53,500 miles on it. I don’t drive it that much because I have a company vehicle. I bought it “as is” so I cannot take it back to the dealer. I’ve heard that maybe the synchronizers might need to be replaced which would basically constitute a transmission rebuild. I’m trying to avoid that. It has the 4.0L straight 6 with the 6-speed NSG370 manual transmission.

Problem #2…I also have the check engine light on and the code says its an issue with a “leak” somewhere in either the exhaust system or it could be the gas cap. The gas cap is aftermarket locking gas cap, not OEM. I have read some other posts dealing with this CEL issue and will try the oil around the seal or just replacing the cap with an OEM cap from the dealership. When I fill up at the pump and lock the nozzle it always overflows and gas spills out onto the paint and onto the ground. Whatever the mechanism is that shuts off the pump before the fuel overflows does not seem to be working. I also suspect that this issue was caused by the flooding, screwing up some sort of sensor.

Other than these two issues I love my Jeep and will probably always own one. I hope somebody out there can help. Thanks.
