Ok the car is a 92 190e 2.6

Here is the situation

Car drives around all week normally, I spend the weekends at my fiancee's home in NYC, so the car stays parked for 2 days straight.

Car starts fine, but leaving the garage there is a right turn up to about a 30 degree incline, you have to roll up this hill while accelerating from a dead stop (merging into traffic)

For two weeks in a row now, the trans feels like its slipping horribly getting rolling up the hill. The engine climbs to 4k+ rpm, and the car feels like it jerks forward, sort of like pulsating up the hill, with 3-4 jerks forward, and once it gets past that it is fine. Drives the 80 miles home, trans feels fine.

Around town during the week I never experience any slipping, or abnormal shifts, except for a rather staught 2-3 shift when the car is cold and trying to hold on to 2nd gear in the morning.

Any ideas on what could be causing this specific situation.

What to look at first? All help appreciated.

Thanks in advance,

Well, I wasn't there, and with only your wording, considering the season - any chance there was black ice on the pavement?

Steve

Basically it was dry... no wheelspin, just what felt like the trans slipping horribly.....

I'm going to check the level and possibly do a preemptive fluid filter change as soon as we thaw out a bit.... 22 inches on the ground so far and still falling hard....

The first thing you should check is the fluid level. The flexible trans fluid lines that go to the radiator start to leak after 10+ years. All of a sudden the fluid is low enough to slip whn its cold. The fluid expands when it gets hot. A filter and fluid change would also be good.

Had this happen once. I changed the fluid/filter and everything was fine after that. Hopefully that will be your case too.
