Just go buy a Gregory's Manual. There are lots and lots of differences between the series 1, series 1.5 (1990) and series 2 engines.

I presume the reason your mechanic says this is because the crankshaft is different between the manual and automatic versions, except for the series 2 (1991) which have the same crankshaft in both auto and manual engines.
