1976 300D slow shifting

The tranny is having a hard time shifting from 1 to 2. Engine revs high and when I let off the gas it slowly shifts. Very hard to drive in stop and go traffic. Background: Recently tranny related problem occurred a couple of months ago when I replaced the tranny oil cooler lines that lead to the radiator. Fitting inside the radiator broke and leaked coolant back to the tranny. I've drained the fluid and replaced the filter,(also fixed the radiator) but now it's having a hard time shifting. Don't think vacuum modulation is on my car, but I don't know as I can't find any information on this. Please help. I'm in the middle of a 3,000 mile long road trip. Thanks

I would suggest a power flush of the tranny. It appears you still have coolant in some of the circuits.
