The New Venture Gear NV 3500  is a 5 speed  manual transmission
   used on light duty trucks with the 4.3L  engine. The  NV 3500 is
 identified   by RPO M50 and RPO MG5. The difference  between
 the RPO codes    is the first speed gear  ratios that the transmission  has.
 The shift assembly   design inside  the NV 3500 transmission  installed
 on C/K trucks   is different than the NV 3500 transmissions
  installed in smaller  S/T trucks.  The distance between  the input
 shaft and the countershaft  is 85 mm  (0.132 in). The transmission
  is available in rear   wheel drive and  four wheel drive.
The transmission has the following features:
|     •  | Constant mesh helical gearing for reduced noise | 
 
|     •  | A 2 piece aluminum housing | 
 
|     •  | Synchronized shifting in all gears | 
 
|     •  | A shift tower mounted shift lever | 
 
|     •  | A single rail shift system | 
 
|     •  | A vehicle speed sensor (VSS) |
