1993 New Venture Gear released the NV3500. Externally the earlier GM units "look like" the NV3500 however internal components were extensively re-designed.

I would look for a NV3500 for a replacemnet out of a newer truck.

Note: All the illustrations in the 1993 service manuals are of a 5LM60, with multiple shift rails, so I don’t know when they switched to using only the NV3500 in production.

I would stay away from anything built before 1991

Remember from the outside these transmissions look alike.

Sorry – I have not saved any identification number information for identifying them.
