Still no conclusive answer. If it wasn't 10 degrees outside, I'd crawl under and try to get some numbers off of it.

Anyone know exactly where they are located?

We need dr. Bob to go do some spirited driving and let us know how his behaves

Sounds like a plan! I'll gt on it as soon as the snow clears and the road de-icer has been washed off by a few rain showers. None of that is going to happen in the next week or two.

Car is hibernating until spring. Daytime temps today expected to get up into the tropical-teens after overnight temps near zero. Performance driving/testing is not an option right now.

Back to our regularly scheduled activities...

My heart goes out to you Dr. Bob. I feel for all the folk that cannot drive their cars year round, but I do understand the reasons.

I'll be thinking about you this weekend as I'm driving mine.

Hi John, and thanks for the kind thoughts. There are certainly pluses and minuses with the move from SoCal to central Oregon. I only need to drive a short ways to get to the ski areas. Just can't do it in the 928 in the winter months.

I did a few mountain trips from SoCal to my place in Mammoth Lakes, but only once did I get into some very early-season snow. No episodes on that trip other than the need for some serious cleaning when it got home. The cars do very well in winter, and I could undoubtedly drive mine with the AS3's on it for more of the year here. But no reason to expose it to the deicer and cinders that ODOT applies to their highways.

Not from the factory.

I'm thinking since these converters are not lockup, that the rpm discrepancy is just the converter loss. It's ironic how perfectly the numbers work out, but based on feedback it sounds like this is normal.

I tried to get the numbers off the bottom of the housing, but I didn't lift the car, and couldn't get a good shot. They almost look missing.

I think you ars taking a picture at the wrong location. Time to get your hands dirty and find out if your unique snowflake is real.

Once the weather warms up a bit I'll dig deeper. That's the right location per the service manual. I'll do some betterrific cleaning any figure it out for sure.

I'm still betting on torque converter losses...
