Default 92 Corsica Transmission Issue

All:
I recently replaced the transmission in my daughter's 92 Corsica. The "new" transmission has a double pigtail connector coming off of the transmission and the old one had just a single connector.


I was able to swap them over, but now the new transmission winds out 1st gear to about 25-30 then upshifts. I have no idea what year the new transmission is.


Could the delay in shifting be due an electrical issue?


The transmission in question is a TH-125C / 3T40.


Thanks for ideas !!!
