Question about a used Transmission

[Saxman]

I'm looking at buying the transmission out of a lightly crashed 1996 SVX with 84,000 miles on it. It's still in the car, and they say that it runs good and there's nothing wrong with it. I'm already planning on buying the ECUtune TCU right away, and the Valve body eventually.

Does anyone have any input on whether or not this transmission would be a good replacement? They want $1000 for it and it doesn't seem like they're going to budge on the price at all.

They upgraded the clutch packs after like '95 right? Should I bother going into the tail end of the transmission and replacing the transfer clutches? Should I buy the transfer clutch drum upgrade from ECUtune?
