Torry33 Posted June 6, 2017 Share Posted June 6, 2017 (edited) yes it is!the long linkage arm on top controls the dual range. Edited June 6, 2017 by Torry33 Link to comment Share on other sites More sharing options...
Numbchux Posted June 6, 2017 Share Posted June 6, 2017 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. Link to comment Share on other sites More sharing options...
Gloyale Posted June 6, 2017 Share Posted June 6, 2017 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 1 Link to comment Share on other sites More sharing options...
