There is a diy EV conversion community where people sometimes leave the (mostly but not always manual) gearbox in place.
Usually they don’t bother fitting a clutch and most of the time they leave it in either 3rd, 4th or 5th gear. Shifting done either when standing or by relaxing tourque. Even reverse is done electrically but rotating the engine the other ways.

One of the fun things about most EVs is that they could accelerate just as fast in reverse, and hit the same top speed, as they could if they were driving forward. The only thing that prevents it is software. For example, if it was not limited by software, a Model S Plaid could do 0-60 in reverse faster than any car in the world has ever done 0-60 going forward.
- jnsaff2 4y agoThere is one nuance tho, specifically with the Model S (not sure about plaid). The way the Model S motor is laid out, it is often more advantageous to fit it backwards into conversions. This should be fine, except the motor driven oil pump is meant to run mostly forwards and long periods of running it the other way cause problems in oil flow and might cause pump failures too. So there is a aftermarket oil pump that fixes this problem.
