Outer Limits 4x4 Board

The Auto box on my 1994, 2.7 TD mistral has shit itself, found a terrano autobox & enginer from a 1991 model. Does anyone know if the running gear is the same?

Straight swop - need some modifications - don't even try it?

Should fit without major changes. The Mistral/Terrano II uses 99% of the Terrano running gear. Intercooler and electronic diesel pump came after '96 if I remember correctly.
