Driving this evening my Check Engine light came on, then the idle started running eratic. Changing up to 200 rpm at idle, but still pulling strong with no stumble above 1,000 rpm. Any ideas?

Thanks in advance

Yes it is true. My 1999 C2 rear deck lid tail no longer raises. I get a red dash light now when I start it up showing the rear tail. What should I look for?

Thanks in advance

Would Swepco 201 be OK for a 996 manual transmission??

Note: Part numbers sometimes change without notice. Always double check with your supplier that you have the latest part numbers.

Parts you will need:

3-4 liters 999 917 546 00 (Shell) Shell Transaxle (75W-90) or Mobil Mobilube PTX (75W-90)

Approved Manual Transmission Oils

000 043 204 20 Mobil (Mobilube PTX) - 20 liter container

000 043 204 19 Shell (Transaxle) - 20 liter container

999 917 546 00 Shell (Transaxle) - 1 liter container

Note: All are synthetic GL4 and GL5 rated (or "non-conventional processing") oils. GL oils have good light running properties because of their light low-temperature viscosity as well as a high level of temperature stability.

Tools you will need:

Tire ramps or jack

17 mm allen for the fill plug image

16 mm triple square with a hole in the middle for the drain plug image

(some cars have an allen type drain plug)

3 quart oil catch pan

Torque wrench (optional)

Drain Transmission Oil

Transmission oil should be changed when the engine/transmission has reached normal operating temperature. CAUTION - oil will be hot, take adequate precautions to avoid being burned.

1. Use ramps or jack up the vehicle at the points provided.
   
2. Remove underside panels to access the transmission. (Boxster owners you need to loosen the diagonal braces and then remove the transverse strut member. A little more work on a Boxster. When you put them back they need to have the bolts torqued to 48 ft lbs. (65 nm). See images Image 1 Image 2 Image 3 Image 4 Image 5 ) (images courtesy of scherb)
   
3. Place oil collection pan under the transmission (at least 9 quarts). Always dispose of the waste oil in accordance with local legal requirements.
   
4. Unscrew oil filler screw (1).
   
5. Unscrew oil drain screw (2) and drain transmission oil.
   
6. Wait about 20 minutes for all the old oil to drain.
   
   

Fill Transmission Oil

1. Clean oil drain and oil filler screw.
   
2. Screw in oil drain screw. Tightening torque: 22 ft-lb.
   
3. Fill with gear oil up to the bottom edge of the oil filler opening.
   
4. Screw in oil filler screw. Tightening torque: 22 ft-lb.
   
5. Install underside panels.

I could only find 15W-50W the other day, is this too heavy to use in a low mileage motor?

Loren: Great post, thank you! It appears that Castrol 5w50 is no longer an approved oil. Some people say that 0w40 is too fluid and may cause leaks (used b/c of better fuel economy) and that the 40 weight is not viscous enough for hot climates like the Southern US. Your view?

I recently did my first oil change and went with Castrol 5w50. Mobil1 doesn't appear to make a 5w50 or 5w40 any more. Should I just use the factory 0w40?

Thanks!

That was the belief for older porsches (964 and back) which used thicker oils as standard.

Mobil does make a 5W50... it's just not available in the US. 5W50 isn't necessary unless you live in tropical climates like on the equator and drive city. Porsche puts in 0W40 and wouldn't do so if the oil would fail in warmer climates.

What speakers are you finding that fit well into the standard location ?

I'm very tired of listening to my standard 1999 C2 system

thanks
