Need help with ID. Is this a 3.9 dual range transaxle?

yes it is!the long linkage arm on top controls the dual range.

It definitely is a 5-speed dual Range. I'm not sure I know the center diff housings well enough to rule out an RX FT4WD trans, which would be a 3.7. Those are very rare.

Count splines on the stubs to determine if it's a 3.9 or 3.7

 

23 splines, would be from an 85-87 Carbed GL  (no "neutral" signal switch)

 

25 splines would be from an 85,86 MPFI Turbo car.  3.7 ratio

 

 

.....except then it would have a neutral switch for the MPFI, so I would say it's 99% likely a 3.9 ratio.  Unless the rear transfer section has been swapped. Then it could be a 3.7 turbo still if it's got 25 spline stubs

Thank you all for the great responses. The community has been a huge help.
