Sorry mate, sounds like a clutch has gone in the box (yes auto transmissions have many clutches) it's highly unlikely to be electrical (although not completely impossible) as most clutches work hydraulically/mechanically as opposed to electro/mechanically and in either case the clutch friction material needs to be in good shape to operate effectively.

Try driving 10 miles (standard gearbox warming up procedure)...then park on level ground. With the engine running, then pass the box through every gear three times (that is to say... P...R...D...N...3...2...1...2...3...N...D...R...P. ..R...D...N...3...2...1) and back to Park. Then with the engine RUNNING AND IN PARK WITH THE HANDBRAKE ON, STANDING TO THE SIDE AND NOT IN FRONT OF THE VEHICLE dip the gearbox oil using its gearbox dipstick, wipe clean and redip. My guess is you will find it (the oil) dark brown or grey as opposed to the bright pink/red that automatic transmission fluid (ATF) should be. If it is thus the fluid is contaminated by either a clutch or brake band lining failure. If no fluid is visible on the stick then top up and repeat the complete procedure including the 10 mile warming up road test.

P.S Engine and gearbox are different entities....No need to replace an engine along with a gearbox when only one is giving trouble....and vice versa.
