'97 C230, CEL Code P1747: Urgent?

[Benzadmiral]

Hey, all,

For the last week the 722.6 transmission has been acting a little oddly. I'd brake sharply, and then if I tried to accelerate immediately, the transmission would seem as though it were not engaging. I'd give it gas, and then it would shift properly. This didn't happen if I braked sharply and then waited a second to accelerate. I was planning to have a fluid and filter change done this month; it's been about 4.5 years and 35K miles since it was done at the dealer for the previous owner.

Today, as I sprang onto the Greater New Orleans Bridge at rush hour, I braked sharply . . . and felt a jerk, and my Check Engine Light came on!

The car seemed to drive normally, though. I went to Autozone to get a quick code check, and the scanner came up with P1747, "Pressure Control Solenoid 'A' short circuit." The CEL was out when I restarted the car after this, and didn't come on during the 3-mile drive home. Again, the car seemed okay.

I've done a search, and found nothing on this topic. Any ideas? I'll call my regular Merc independent tomorrow, Friday, but he probably won't be able to take the car until Tuesday or so. In the meantime, I need the car for errands and to get to work. Will I be okay until next week? Are we talking about major tranny work?

TIA,
