Thank you crwarren11 and JFP in PA for your help on this.

The indy came highly recommended by other Boxster owners, and seems to me to be operating genuinely in the best interest of the car. They went over the complete refilling operation with me and they say they did all the correct steps for proper fill - correct temperature, shift the gears, fill again, etc. I only question because I didn't see it with my own eyes so I'm including this in my list of "could it be this?". Well, not to slight your shop in anyway, but one of the most common problems with the Tip is both fluid choices and filling procedures; more often than not, we find recently serviced Tips with problems are not filled correctly, or have the wrong fluid in them. Because the filling and testing procedures take time, a lot of shops seem to try and short cut them to save money. Point taken. I'm not invested in defending nor persecuting this shop because, so far, I have no evidence of malfeasance. Fluid level is something I am very interested in checking, so I'm gearing myself up for being able to do so the weekend after this. I've read up on good ways to place the car on jack stands so I'm pretty clear on that. What I'm not sure about is which fluid I should get. Is the factory fill a ZF or Pentosin? because I'd like to use what was in the tranny from new because it did its job so well.

Well your recommendation is certainly easy and non-invasive enough to try! I'll give it a go. If the issue persists my next thought is to "drain and fill and run the car" a couple times to "flush" the fluid using Pentosin or ZF. If I would've known better at the time I would have insisted on using the Porsche recommended fluid - cost of the fluid is not a consideration to me on this service - I was simply ignorant of the facts.

Hi All. Bought my Boxster with 30,000 miles on it in August, had a few things serviced in October including LN IMS Retrofit bearing, AOS, NGK BKR6EK plugs, and a trans fluid and filter change. Prior to service it would shift at 7200 rpm, but now it shifts at about 6800 (edit: should read 6600, not 6800) in first, and 7000 in second and third. The new fluid used is G-052-162-A2. The shifts are not as quite as quick as they were, but this being my first Tip I don't know which way it's supposed to be. I'm wondering if it could be one of the following: 1. Wrong fluid 2. Underfilled 3. Overfilled (yes, I know, but still . . . ) 4. Could something not be fully connected when trans was reinstalled? I've searched and searched on rpm and shift points and haven't seen anything resembling a "a-ha" moment. I welcome your expert thoughts on this. Thanks, Scott ps - I currently have, and have had other cars that are quicker/faster, but this Boxster is far and away the happiest car to drive!

I know this is an old topic, but . . . Mine gets let loose on dry days when there's not much salt on the roads. The top goes down when the temp is high 30's in the daytime, and mid 40's or better at night (the heated seats make this ok).

Great info everybody! I've been wondering about this since I got mine back in August. Seems Simple enough. I'll start at Dawn on the next warm day.

First of all, Thank You to all of you on this forum! It's because of the info I was able to scavenge from here that I was able to make a very informed purchase. I bought a 2004 Boxster Tip w/30,000 miles on it a couple months ago. It had been sitting for about a year from the last owner to the dealer I bought it from. Had a PPI done by my local Porsche dealer which came up with some routine maintenance items that needed attention: battery was under-voltage (my second day with the car and this set the trans into one of the Limp Modes, hasn't happened since new battery), serpentine belt, cabin filter, air filter. After replacing those items I was able to enjoy that car for a while. The car ran great! I knew that I wanted to replace the IMS for my own peace of mind, so I started with an oil change at a very respected and high priced independent shop. They didn't see anything in the oil, but they did recommend IMS replacement due to a tiny amount of oil "fuzz" that was evident on the bottom of the engine just below the IMS. I then found out a couple weeks later that some friends had used a different shop, also very respected in the Porsche community, that was more moderately priced. I went there to check it out and was happy to bring my car in. The AOS wasn't in horrible shape but needed replacing, especially since we were "already there, so why not?". They cleaned the intakes and replaced the plugs. The RMS wasn't leaking at all, replaced it also for the same reason. The IMS was replaced, and after it was out I could see that the old bearing was starting to "wobble". If you put the bearing in a vise, the shaft can be tilted more than 1/16"! The seals "look" ok, but I don't know how the inside looks because I haven't taken it apart. Other than the wobble there is nothing that would indicate anything bad was going on. The old bearing turns just fine. So after another oil change (I didn't mind doing it again because I wanted it flushed anyhow), and a trans filter and fluid change, I'm off to the races so to speak. The car runs even better than before!! I think this is due to the intake cleaning and new plugs. The engine idles smoother, revs smoother, pulls more evenly through the entire rev range instead of being lumpy - even up to 4,000 rpm then a burst of power, then softens after 5,000. Now the power feels very consistent, and it's a little more than a tenth of a second quicker 0-60 (wristwatch chrono). The only thing I can even complain about is the fact that the tip now shifts into 2nd gear at about 6,700 rpm instead of about 7,100 like it did before service. 2nd-3rd gear happens closer to redline but not as close as before the service. Might it be a little quicker if it would shift closer to redline? Or is it maybe a little quicker shifting at a lower rpm? I don't know. Also, is it possible that the trans needs to "learn" to shift differently since it just had a major service? I've only driven less than 100 miles since getting the car back. I just wanted to share my experience with any that might benefit from it.
