In 1987 it was referred to as MG-290 My guess is the G is for Getrag
In 1988 it was referred to as HM-290 HM= Hydramatic / Muncie
In 1989 it was referred to as 5LM60
In 1991 it was referred to as NVG 5LM60 NVG= New Venture Gear
In 1993 New Venture Gear released the NV3500. Externally the earlier GM units "look like" the NV3500 however internal components were extensively re-designed.

Thanks for the info, now to figure out if it will bolt behind a 250 straight six.

Re: which 5 speed

The 1990 had the first design bearings I had information about in the links.

I am no fan of that vintage of the transmission, and would never recommend anyone use it in any car or truck.

The NV3500 I would be ok with in light duty applications.
