Question about 2002 Saab 9-5

Multi-Function Transmission Range Switch

This is more of a question than a problem but I have an 1998 Audi A4 Quattro 1.8T and my transmission is busted. I have completely lost overdrive, it cluncks into gear when I'm stopping, and my reverse sometimes works and sometimes doesn't. Also, I don't know if this has anything to do with it but the thing on my dash that says "P D N R" doesn't work. They are ALL always lit up. I have already took it to a shop and they told me I needed a new Transmission Control Module. So I got that replaced and it didn't do anything to fix the problem. (and they broke the clip my boyfriend had to replace.) So my boyfriend (a mechanic) and I have decided to go at this on our own. I was wondering if any one knew where to get or how much a Multi-Function Transmission Range Switch costs? I'm very limited on money at the time. I'm not trying to take it to a shop or a dealership. Just too much money :/

Thanks! I really appreciate it!

I have a 1998 A4 2.8 tiptronic and it just started having very similar issues... reverse works sometimes, tiptronic shift mode doesn't work and ALL the PRND lights are lit up (maybe its a little clunky, by can't say I really noticed). Mine has only been like this for a day, but I brought it to the Audi dealer and they sourced the codes and said its the transmission range switch. I haven't had it fixed yet, but they say that the diagnosis is certain. Only problem is their quote is around $1100 (switch $600, install $500 for about 4hrs to take apart the center console). May try to do it myself. I believe its just by the shifter under the center console. Hope this helps. Good luck.

The best solution is to visit this website i know what your thinking but trust me it will help wonders. You input your info for the car and zipcode and it finds the closest location of the part your looking for. It is sorted by price and condition of the item you need.

Soudns like your transmission is slipping in and out of gears.-TCM is only necessary if it's acting up in one gear or two. The reason your display shows all of them lit is because the sensors are screwed up from your trans synchronizers being warned down. Or your not getting proper lubrication and it's causing the transmission and things like the crank sensor to give the CPU bad readings-Thus leds are lit up. I would test first for the Crank Sensor (voltage), than replace the inexpensive things like Filter and Screen, and flush and refill the fluid!-If it's manual or auto-the clutch and flywheel cannot grip the gears properly.

An overdrive is a device that allow the choice of an extra-high overall gear ratio for high speed cruising, thus saves on gas by using less torque. usually used by third or fourth gear. the overdrive sits in the back of the gearbox and is controlled electronically or hydraulicly controlled. if your sensors are flickering around in there it wont go on, or if fluid is low the hydraulic pressure wont be high enough.

Hope this helps. Good luck.

    Also, it might be Range Sensor! and not a switch depending if it's auot or manual. And it's not multi functional range switch normally called Traction control switch or Traction Control module or Transmission Control Switch or range.

SOURCE: audi a4 quattro

a rubber one,should be changed at 50-60,000 miles. Audis recomendation is like 90,000 I think but have heard of them going much sooner than that. A preventitive Cam -timing belt job way cheaper than doing it after it breaks and ruins valves and cylinders!

SOURCE: can 2001 a4 quattro low oil light be reset

No, it goes out when the oil level is read to be correct. If you have the right amount of oil in the car, your pressure sensor is bad or you have oil sludge blocking the pickup tube at the oil pump. Run some Seafoam in the oil for 100 miles and then change the oil and filter (or if the pressure light stays on, add half a can of Seafoam and idle it for 20 minutes before changing the oil). Repeat 2-3 times and see if it goes away. If not, change the pressure sensor (on the oil cooler - the aluminum block the filter screws onto). If this still isn't a fix, you need a desludging kit from If THAT doesn't fix it, drop the oil pan and change the pickup tube and filter screen, clean out the pan, and repeat the Seafoam treatment.

Check your transmission fluid. If you have not changed it in 75,000 miles change it. This is the cheapest fix before you look at more expensive repairs.

Multi-Function Transmission Range Switch

rather odd thing to try while i'm looking for a price .... but i've read that a method to reset that is to start it ... hold the gas pedal down abit and shut off the key will holding down the gas pedal.... hold that you should hear some clicking... that should reset it

it's been suggested that either water or rusty pins can be the cause of it.
