I'm going to assume that the shop diagnosis is correct. To do virtually any transmission repair except minor seal changes and filter changes, the unit must be removed and torn apart. This is because all internal components are basically strung together on the mainshaft (picture a bunch of doughnuts on a broomstick). Therefore since the "broomstick" can only be removed from the front of the unit, that's all they can do. Many shops do not have an in-house transmission expert. It is more reliable for them to use a "certa" unit which is a factory rebuild, rather than needing to rely on local shops for this work.
Therefore, even if your problem is small, it still takes a complete teardown to repair it...better to just put in a different one. If you doubt the diagnosis, have an independent shop verify the dealers findings.!!
Good luck

My over drive light keeps blinking periodically on my ford escape 2003. it seems to drive fine, I just had the transmission replaced 2 months ago. What could the problem be?

Get it back to where you took it to be fixed ASAP. You should definitely have, AT THE VERY LEAST, a 90 day warranty. This seems like it's something that wasn't reconnected properly or at all. Good luck!

I owe a lexus lx 570 2011, the issue that I am having is that the engine seems to be slipping when i try to accelerate I have taking it to the lexus dealer ship however they seem to say that there is no...

Your still under warranty I would make them have an service adviser ride with you to see the issue. If the transmission is slipping it can be a few things internally like torque converter, and so on. I would also check for any recalls on the vehicle. But I wouldn't let the dealer push you around, cause what do you bet they find the issue once your out of warranty. Just be firm with them.

My 2000 Lexus RX 300 Sunroof is stock and is not closing. electric motor seem to be working but is stock in one position. any idea how to fix this sunroof?

I have the same problem..... took my 2000 RX300 to the dealer - was told they need to replace the motor and the tracks and quoted me a price of $4500.00...... NO THANK YOU.... This dealer will not sell parts for this to local garages. Can't believe they can get away with that. Since I don't really us it a mechanic told me to take it to a glass company and just have them seal it closed to stop leaks.

Am looking to buy a '99 through '01 Lexus Rx 300, and was told by a broker that so many have transmission failures at 50k-100k that he doesn't sell them any longer. This seems contrary to my research, so...

well from doing a quick search i see the dealer was right. Read here for 1999 there are lots of people that say transmission failure. the RX 300 was built with a camry transmission that could not handle the torque. They used the same transmission till mid 2000 and most 2001's seem to have a transaxle defect. Also these years have reports of significant problems with the engine. Your best bet is to look into a different generation of the RX. Here are more reviews covering 1999-2003 with the same problem. Click here to see collected reviews. If i were you save yourself the headache and the money in your pocket with the repair bills. Unless that is you like to repair your own vehicle and not drive it for days at a time every few years. Then its the car for you. Wasnt till i saw this problem that i thought about how when i worked in a Auto repair shop how many of these rx 300's we worked on. If you need further assistance or would like more reviews please let me know and i will be glad to assist you further. Thanks, Midwest-tek

I have an 03 Lexus LS430 with 64K miles. Trans is

The weakest link is on the transmission pan gasket.

You have to buy the transmission service kit.

The kit has the pan gasket and the transmission filter.

My cost is only $ is a lot more.

Use Amsoil Synthetic ATF if possible. It will help increase the service life of the transmission

HID low beam headlight replacement for 2003 lexus es300

The HID bulbs are very easy to change, and can be bought online for much less than from the dealer. Check sites like xenondepot and Ebay for Phillips D2R (for reflector headlamps) HID bulbs and you can replace them yourself.

RPM shot up to 4.5/5 while idling

I have a 2003 Acura TLS, bought new Oct 2002 currently with only 42600 KM (real low) My problem appears to be the same. I noticed specificly on warm days after 30 min driving, when coming to a stop, the idle was about 3500 RPM. Parked the car, turned it off. When starting up again, RPM stayed at 3200, also couldn't put into drive (possibly safety mechanism to prevent damage to transmission). After 30 min when cooled, was able to start again - OK.
I brought it to the dealer thinking possibly connected to FAULTY TRANSMISSION". There was a special extended warranty issued by ACURA >>> I believe it also includes 2002's. Your Dealer should check into it again.
My dealer, ACURA LAVAL (in Que, Canada) seemed to look at nothing else than the transmission. In fact, 2 days after not hearing from him, he told me that they had already ordered a NEW Transmission which is being put in as I write.

Hope this is helpful to any Owner/Dealer who reads this

I had this same problem back in November during a very cold spell.I had an appointment to have some "recall" work done on my 03 passat and told them about the STOP brake light. When I picked up my car, the dealer told me that it just needed some brake fluid??, so they filled it ! Well, I don't know about that, but I haven't seen that pesky STOP warning light since.

YEs brakes can do this for sure! If its rotational or rhythmical it has to do with your wheel. Take off your driver side tire and inspect brake pads. At 65k miles you are most likely due for some new brake pads. DOnt take it to the dealer they will charge you a fortune.
