1992 300SE 140 Chassis Instrument/Transmission Query

Submitted by twh72 on 13 May 2008 - 4:58am.

1992 300Se (140 chassis) has 4 speed automatic, tranny just rebuilt. Worked fine, then instrument cluster failed (speedo/tach/odometers not working). Car will not shift into 4th gear now. is this related to cluster failure?
