The switch arrived at the dealership, went to pick it up, it was the brake pedal switch......

I checked a fuse, according to the service/porsche-book at the drivers side, dont remeber the exact fuse number, but that one was fine

Per the manual, the tranny is filled until ~11mm BELOW the fill hole.
Replace reverse light switch and the reverse lights were ok

I recently noticed my reverse lights no longer work, since both light bulbs checked out fine, the reverse switch is most likely the culprit.

I only changed the transmission fluid a couple of years ago, so only has about 6,000 miles on it, but yes I plan to check the fluid level once I look up how to.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I found Car Quest to have this part, see
http://www.myvirtualpaper.com/doc/ca...1/805.html#804
lower right hand corner, part number 53-11798
Porsche number is 996.606.103.01.
Best part of this is the cost, it's only $9 or so tax in even up here with 13% tax.
I changed mine a few years back. Be careful with non-oem. I bought an aftermarket part, installed it and it leaked transmission fluid so I tried to tighten it and snapped in half. The DIY is straight forward. The sucking sound you will hear when you remove the old one will surprise you....don't worry about the gurgle. The switch is on the top left (drivers side). Feel for the wire and you are home. Good luck!
Thanks for the heads-up! I haven't install it yet due to time constraint.
There was no O-ring or crush washer with the new switch, I think I may go get a fiber or aluminum washer to seal against possible leakage.
That's good to hear, I'd prefer to craw underneath the car only once to do this.
I also didn't bother picking up any gasket, if it's not leaking now then the new switch shouldn't either, I might put some heavy grease on the thread of the switch when installing to prevent the thin transmission fluid from seeping out.
I'm somewhat surprised the reverse switch has already failed with a little over 60K miles, I have never had a reverse switch fail in any of my other cars or anyone I know of, especially considering this car is unused for 4 or 5 months every year.
At least the part is cheap!
Mine failed at about the same mileage. Was super easy to get off, surprising given it was on there for 14 years! The part was only $11.00 from Pelican. Very easy to put the new one on and it did not have a gasket of any kind between the part and the transmission.
$17 would likely double by the time the S&H and local taxes are added.
Just did the replacement, super easy job, that is once I found the switch, somewhere I read the switch is in the driver's side, so I jacked up the driver's side to gain access.
Nope, it's not on the driver's side, unless it was an UK or Aussie car......
For anyone doing this job, the switch is located at the front passenger side corner of the transmission housing, facing up, right by where the shifting bell-cranks and mechanism are under the car.
Mine went right around the 60000 mile mark same as yours. Doddle of a job to change. No need for anything only the switch just lightly tightened. Pull the wires off. Exchange the switch. Stick the wires back on. Easiest DIY ever. 5mins mins work tops.
Well Pete, here I am not even two years later with a leaky switch by going the aftermarket route.........., it may have been slowly leaking for quite sometime, but only finally started dripping onto the garage floor this year.
Guess I will pony up for the OEM switch this time!
I only changed the transmission fluid a couple of years ago, so only has about 6,000 miles on it, but yes I plan to check the fluid level once I look up how to.
The filler hole is on the side at the top. You top up the oil till it runs out the hole. You will need a separate squeezable bottle with a plastic bendable spout as there is no room to pour the oil into the hole. Obviously if you plan on changing the transmission oil totally, the release oil plug is lower on the side or under the transmission casing.
Don't be so quick to judge!!
Lesson learned today, well actually from yesterday but did not realize until today, is:
"DO NOT JACK UP ONLY THE REAR END OF THESE 996 AND REMOVE THE REVERSE SWITCH"
A big puddle of transmission fluid on the garage floor awaits me when I got home today is why I should have also jacked up the front end of the car yesterday......
Hurdi,
Just pluck the transmission out and you won't need the squeezy bottle with a bendable spout. You can just turn the trans on its side and pour the oil in.
That's not true, actually. Per the manual, the tranny is filled until ~11mm BELOW the fill hole. Most people make a simple tool with a paper clip to check the level.
Could you please share your source of this info? I've never heard of that and the factory procedures call for filling to the bottom edge of the fill hole

Ahsai,
It was from Pelican Tech Articles, I had also come across that a couple of days ago, although it's under the "911" grouping so potentially it's for older air-cooled 911 vs. the water-cooled 996.
Here's the link
http://www.pelicanparts.com/techarti...sion_Fluid.htm
I think I would go with even to the bottom of the fill hole approach on Renntech under 996 heading.
BTW, I looked on-line and locally for a quality replacement switch, believe it or not the same switch is used in early 2000' vintage Cadillac and SAAB and (gulp) Pontiac vehicles, so there are many crossed numbers and options, anything from $10 to $50.
Pelican Porsche unit would be $22 + S&H
Decided to call the local Porsche dealer near my house this morning, $25 + tax, I was sold.
The switch arrived at the dealership, went to pick it up, it was the brake pedal switch......
Pretty sure I was 150% clear I was looking for the reverse light switch.
Won't likely get the car on the road for a few more days, sigh.........
Hello
I also discoverd problems with my reverse lights/reverse light switch.
First I replaced the reverse light switch and the reverse lights were ok. Some days later the reverse lights are not working.
Now I noticed a strange thing, sometimes my reverse ligts are working, some days not. Putting my 996 (with ignition on) in reverse, maybe after 20 seconds or so (different from day to day) the reverse light lightens up, but sometimes not.
I took out the switch out of the gearbox and pushed by hand, no problems, lights are working. I pushed in a small wire between the conecctor and lights are constantly on... Blubs are fine. When the reverse lights are not working (ignition on, gear in reverse) there is no 12 volt back at the connector at the lights.
I mounted a rear view camera this spring thats how I discoverd the problem. I have the rear view camera NOT connected and still the same problems.
I checked a fuse, according to the service/porsche-book at the drivers side, dont remeber the exact fuse number, but that one was fine
My thoughts; A ground problem should not be the problem, since with that wire in that connector lights are on. Could it be a bushing in my gear-linkage, so I am not hitting the reverse swicht correcly. To be honest, changing gears feels good, nothing fluppy or loose....
Anyone suggestions, what I could check/search for more? My old reverse switch was definetly not working.
