A classic example of "he's forgotten more than I know".
From my perspective the question still remains is will the 722.414 work properly bolted behind a n/a 2.5. As I said before, the physical dimensions / bolt patterns are the same. My local tranny guy said the turbo model was a "beefed up" version of the 722.413. His opinion was the 722.403, 722.413, and 722.414 were all interchangable and if one were searching for a replacement of a 722.403 or 722.413, that a 722.414 was the best option.
This info is from the local transmission shop and is not being presented as absolute fact and I was hoping someone on the forum with MB tranny expertise could confirm or deny this.

Starting my Diesel conversion 2.2 into 87 190E body using a gasser tranny (722.408 or 409) behind his diesel so it might be that all trannys from this era swap with only minor differences or improvements / upgrades differentiate within this tranny family through the years?
I PM'ed GregMN so maybe he will join the discussion.
