You're seriously just going to swap trannies? If you know what you're doing, forgive me. I've looked into this myself and every person I asked basically told me the same thing. The cost of doing this is more than it's worth, and you will kill the value of the car. You'd be much better off selling your 5AT and buying a 6MT
Don't even go there, As DiRN has said the cheapest way is to sell the auto & buy a manual.
The swap is a lot more than just the transmission, it includes the full power train wiring loom, ECU, Instument cluster ext, ext , ext.
A few years back I imported a 99 Vvti Supra twin turbo that had been converted to manual in japan. It had a new Getrag 6 speed fitted but the car would not run properly as the ECU was looking for an auto. I purchsed a manual ecu. Would not fit, different plug layout.
I'll cut the story short by saying it took many months to get it right.
I bought it cheap & it was a genuine low K car, but I had to sell it cheaply as it was never going to be perfect without major expence
In old cars doing a trans swap is easy (it seems like I read about an auto-to-manual conversions in Silvia once every month) but, in your modern car, its an absolute nightmare.
As people have said, your electrics are hooked up into your transmission. Its not just swapping out the bell housing like in the old days. And then there's a whole bunch of stuff that just might not work afterwards.
If you've seen the light and want a car with a gearbox, go buy a vehicle with one. The amount of headaches you'll get trying to do a conversion are just not worth it.
