I just swapped a 1983 euro 240D motor into my dads 1983 USA 240D. The euro donor car was a 4speed. My dads car is an automatic. Started up and running great. However it shifts incredibly early. 1-2 takes place at like 5mph.

Researching the vacuum system I realized I don't have a vacuum control valve on my injection pump (obviously I guess, as the donor was a 4speed) but it doesn't look like there are the same tapped holes to add a VCV to the euro pump. But the car is not near me right now to verify.

I saved the injection pump from the old motor which ran and idled okay but suffered from a case of the vacuum pump dropping its innards into the timing case. Can I swap the USA automatic injection pump onto the euro motor if there isn't a way to hook up a VCV to the pump in the car right now.
