Peugeot engine swap in Citroen Grand Picasso 2017

[LJcardriver]

I am looking for an exchange engine for a Citroen Grand Picasso 2017 automatic, engine code DV6FC BHZ, and I hope you can help me with the right answers to the following questions:

1.Do I need to be aware of whether the exchange engine is for a manual or automatic transmission, or does the engine fit independently of the transmission? In otherwords will a engine of a manual transmission fit in a car with automatic transmission.

2.Will an engine from a Peugeot fit into a Citroen without problems, or should I expect software issues?

3.The Citroen engine is a BLUEHDI 120 DV6FC BHZ, and the exchange engine I have in mind is a DVFC BHZ 115 DVFC BHZ. If it has the exact same engine code and exact same enginepartnumber 1612521380, where does the difference in power (120 vs 115) come from (software?), and is this something I need to consider with an exchange engine?

If anyone has answers to any of the above questions, you would help me immensely. Thank you in advance!
