![]() That is the kind of bizarre crap I got routinely from the two Lexus dealers I frequented. Any help or suggestion would be appreciated.:cries: I had not noticed any performance issues with it other than the leak. ![]() It just seems to me you could clean the seal out of the pump by flushing it and then put a new seal on and it would be fine. I would like to know from you guys does this scenario seem possible and am I doing the right thing having the tranny replaced verses attempting to rebuild. Their explaination was the front seal apparently had blown out into my transmission fluid pump and was unrepairable. I got a call from them a couple of hours later saying I needed a new transmission cost $5200. The estimate to repair the seal would be $1500. They did a quick inspection while I was their and said they believe it was the front seal but would have to take it apart to be sure. I have just gotten a diagnosis from lexus concerning my leaking transmission. Any help or suggestion would be appreciated. I was also wondering if the problem will get worse because $1850 will buy alot of transmission fluid. I was curious if anyone else has had a similar problem and what it cost to fix. They told me it was going to cost around $1850 to fix. From my description to them they seemed to think it was the rear main seal leaking. They told me they have not seen that before. I call Lexus to get a price for the repair. I have had a oil and lube guy tell me it was my front seal on my transmission. I have a AWD 1999 RX300 with a transmission leak. I will take it to a dealer shortly and let you guys know the results. It is right before the exhaust bends to go up to the engine. You can actually smell it burning at times. The leak is dripping on the exhast between the engine and transmission. Man I am just not lucky enough for it to be the drain plugs but I will check it for sure. But your garage floor will remain a whole lot cleaner, especially if you lay down some spread-out plastic trash bags on top of the concrete before you lay the cardboard and newspaper down. You'll need to keep refreshing the newspaper fairly frequently, though. Depending on how much is leaking and how quickly, this could be as simple as several layers of cardboard from broken-down cardboard boxes, covered by multiple sheets of newspaper. Oh, one more thing - clean up your garage floor and put down a catch tray that you can always position the vehicle over when you pull into the garage. If tightening your drain plugs doesn't stop your leak, have it checked out and report back to us on what you discover. The crush rings need to be in place on both drain plugs. If your fluid has been changed before and those crush rings were removed by the guy who did your fluid change, that could explain your leak. Both of them should have aluminum crush rings (washers) keeping the bottom of the heads of the drain plugs from contacting the transmission pan and the differential casing. You'll need a 10 mm Allen wrench to tighten those plugs. But you neither want to overfill nor underfill your fluid in order to avoid making your problem worse than it already is.įirst things first, though - ensure that your transmission pan drain plug and front differential drain plug are both screwed in tightly. As long as you're adding the proper amount of fluid to keep the level where it needs to be, you'll be okay for quite some time. ![]() I'd have it examined at a well-respected transmission specialist shop to find out exactly where the leak is and what is probably causing it before I went any further. There are many reports on this forum of RX300 transmission failures, but this is the first one I recall for just a transmission fluid leak.
