You would have to replace the catylitic converter(s) if efficiency is low. In some cases the rear o2 sensors become lazy and can set these codes. You can replace these sensors and see if the codes will go away. In most cases, when converter replacement is required, these sensors are recommended. I would change the rear o2 sensor(s) and hope for the best. Converters are very expensive

If you can't find it, follow the thick cable attached to the positive battery post down, it will be attached to the starter.

Key less remotes all suffer from the same problem, they are poorly built! 99% of the time they stop working because the solder joints on the circuit board that hold the battery in place get loose. Check your unit have a close look at the solder joints, re-solder any loose ones and put in a new battery, it should start working again. I've fixed so many of them with this problem!

In the transmission, that is usually attached to the back of the engine. First look at the engine and take note of where the acessory drive system is located (where the belts spin when the engine is running) that is the front of the engine. Somewhere at the opposite side there will be a dipstic tube that will allow you yo check the transmission fluid. That is unless you have a manual transmission (5 or 6 speed with an additional clutch peddal) there usually isnt a way to check the transmission fluid on a manual transmission. I am only giving you basics as I dont know your car very well, you should be able to find most of the information you need to find the transmission dipstic in your owners manual.

Usually there is a decal under hood which shows this.

Through the transmission dipstic tube. Use a funnel that will fit into the dipstick tube and SLOWLY pour the transmission fluid into the funnel. Remember to have paper towles with you to catch any remainingbfluid that is in the funnel, and make sure the funnel is clean.

if the alarm is sounding the common prob. is the pos. battery supply missing from the fem,[ front electric module] located lh lower A post brown/red wire i think. it sets the security system off after you have locked the car, it thinks the battery has been disconnected. the most likely cause is a corroded open circuit wire around the front bumper/lh wheel arch liner area. the power comes from i think the engine bay fuse box, the other option could be a faulty door or trunk/hood latch

Use a funnel and add into tube where dipstick comes out.

S type jag ,right try this as it often works for me in the cars left at the long term airport parking ,everything from alarms to bits not working,disconnect the battery terminals and then join them together for a at least 15 mins ,or go to local bar for coffee and a ciggy ,one caffine shot and a good cough later go back to car remove the wire from between the battery connectors ,reconnect the battery and its perfect ,everything works ,this also works on some renaults where the wip?rs are controlled by the computer as well and the immobilisor .

I will assume your cylinder misfire issue is gone & all of the Emission Monitors run & all scan tool data is okey,except for the transmission I will also assume your continuing to drive the car, knowing you have a transmission problem I will also tell you that being a 2001,give mileage 150,000 plus, you have a failed transmission I can be more specific & more detailed for the reasons why, but all we can do here & most likely if we had the car,is to pull trans & rebuild it, after some testing of the systems If the trans has just been rebuilt & acting up,take it back If your just dealing with a failed shift solenoid or sensor issue, there is no way we can help in this format without a vehicle Does it go into failsafe & other things Once you drive with a trans issue, you ruin it in a few miles or a few days

you may have an air bubble trapped in the heater core. Bleed the heater hose lines to remove air from that part of the system.
