My 300SD which now has 130K miles on it, has a transmission issue which is beginning to show. When the car hasn't been driven for several days, when I first go to drive it, it takes maybe 10 seconds of applying some throttle before the car starts to move. Then it just slowly starts to move, no lurching, or noise. After that initial start, as long as I use it within maybe 2 days, it starts out normally. I think it may happen more on a slight grade. My guess is that fluid is somehow draining out of maybe the torque converter and it then needs to refill? It's been doing this for a year or so now. No other symptoms, other than MPG seems to have slipped from the usual 26MPG down to about 22MPG. Don't know that there is any relation though. It still has the original injectors and was planning on replacing them soon, as I think that is the most likely MPG issue. Fluid level is normal and was changed around 100K
I have no problem living with the tranny thing Just wondering if anyone has any insight into what it is, will it just remain like this for a long time with no harm, or is it a sign of impending failure, better to address it now, etc?
TIA
