Can you put a 4x4 motor and manual transmission into a 4x2 automatic transmission 2012 Holden Colorado? They're two years apart.
Even if the two cars were from the same production month and year, you’ve got some serious mis-matches there; enough to make the job far more time, effort and money than it’s worth. For a start, the two-wheel-drive Colorado won’t have the extra differential and drive-shafts to mate with the twin drive-shafts that the all-wheel-drive gearbox will have. So you’d have to somehow blank that front driveshaft off. Or, add the front differential and axle which will also probably require different front suspension. Prop-shaft lengths are likely to be different between a manual and an automatic version of the same car, too.
Then there’s all the other things that can suddenly catch you out. In many cases, the manual and automatic versions of a particular car will have different transmission tunnels and different holes in the floor for the shifter to poke through. Even the centre consoles can be non-interchangeable. The dashboard of an automatic car with its PRNDL display will also be different to the manual one. Then there’s the question of wiring looms which can also be vastly different to suit the specific requirements of each driveline layout (a modern automatic needs lots of electrical inputs). In fact, the on-board computer is very likely to be different between the two transmissions on that basis as well.
Following on from that, what about the sensors to control the all-wheel-drive system? Or even the rotary dial inside the car to select the different four-wheel-drive modes? A two-wheel-drive car just won’t have them nor even possibly the access points to add them. And what about the real basics? Things like the automatic car not having a clutch pedal. That requires a full pedal change inside the car. None of this stuff is simple, easy or cheap.
To be honest, the engines themselves are very possibly interchangeable, but even if that’s all you swapped (and not the transmission) you’d still need to change the flywheel and plenty of little details.
By far the best advice is to simply buy the version of the Colorado you want.
