hello, I apologize if this has already been addressed here. I bought the first French Peugeot 306, year of manufacture 1996. After a month, the crankshaft made a hole in the engine block. It is a 1.8 8V 74 kW with automatic transmission. I found a car with a broken manual transmission at a junkyard. Question. Is the manual transmission interchangeable with the automatic on this engine? Or can I replace the engine with a 16 valve variant and keep my automatic transmission? Thank you very much for the answers.
