Can you swap a motor with one that had a different transmission?

Yes, under certain circumstances, and you need to know what you are doing. What I mean is, if you are going from a M/T to an A/T, you may need to remove the pilot bearing from the crankshaft. If you are going into a M/T, you may have to install a pilot bearing. Is this the same size engine, just a different transmission? Or are we also changing engine sizes, or year models? If so, we might have a conflict in wiring or engine controls, so there may be more questions to consider than just the issue of a different transmission.

The short answer is "Yes". However, the swap in question is not an easy one for many backyard mechanics. In order to make the swap happen you will need aftermarket motor mounts, modified axles, a modified wiring harness, a pedal swap, a new center console (to make the shifter look right,) and an upgrade from OBD0 to OBD1.Depending on the trim level of your 1991 Civic, you can swap motors from the same generation Civic (1988-1991) for not only a power increase, but a cheaper and easier swap. So if you have an LX, you could source a D16A6 engine from a Civic SI for a considerable power improvement, and all you will need is the motor and preferably the Engine Control Unit (ECU).The automatic-to-manual swap will require a set of pedals from a 1988-1991 Civic, a manual transmission for the motor you have or want to use with shift linkage, all clutch components with lines and cylinder(s), and an ECU designed for both your motor and transmission.

you have a couple options, you can pull the motor and have it rebuilt swap in a used motor from a junk yard drop the transmission and pull the crank, replacing it with a new crank rods and bearings if you are lucky you may not have scored the crank and you can replace the one bearing ang rod or you can junk/sell the car

Motor or transmission mounts. That or your transmission is slipping one way or the other.
