Weird Shifting

So i purchased a 1991 SC with the automatic transmission and there are 2 big issued with it. 1# the electric cooling fan does not come on normally. I believe it is associated with the temperature sensor wiring as even after a new sensor the temp gauge when hot is barely above C. I'm not sure how the car's ECM controls the fan so that's my best guess.
2# the car shifts very odd. It won't leave 1st until well after 3600RPM, and roughly the same thing with 2nd, but the shift to 3rd is very abrupt, and at a much lower RPM, and it does not go into OD. I was going to replace the valvebody, but i am here for a 2nd opinion.
Talking with the previous owners none of them claim to have installed a shift kit.
