5 spd conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

monza1979 · 08-01-2010, 06:23 AM

What are my options to convert to a 5 speed? Drivetrain consists of a 350ci-sm465-np205. I love the durability of the 465, but i would also love to have an O.D. gear, yet can't afford a Gear Vendors. Not to worried about fabricating some parts, but would love a somewhat bolt on set up. Truck is a 78 swb.

Getrag/NV3500 or NV4500. The light duty was available starting in 88, should be plenty out there. 4500 didn't come out till 92, and mostly in heavy 3/4 ton and 1 tons.

Advance adaptors has what you need for a conversion. NV4500 is top of the line. A NV3500 is suitable for most daily and light duty drivers.

whats the difference between the 3500 & 4500?

monza1979 · 08-01-2010, 11:23 PM

will advanced adapters have an adapter plate for the 4500 to the 205?

gchemist · 08-02-2010, 12:49 AM

SM465 to NV4500 adptor.

Difference? $$$$$ NV4500 are not cheap!

The advance adapters are way too expensive. i plan on getting a 6 bolt np205 when i do my 5 speed swap so it will bolt right together.

The nv3500 was used in light trucks, their not good if your ever going to put the tranny to work because they wont handle abuse or any tourqe whats so ever, if your nice to it an never work it ive HEARD theyll do ok but have heard of people ripping 3 of them up before forking out the money for a tko 600. The nv4500 was in the HD trucks with a granny gear an will hold up to the abuse for pulling and hard work(not racing)the nv4500 is the trans im going to put in my truck next summer and will have a thread about how to do it when im done.

There is also a NV4500HD that is a heavier version of the 4500. One of my dream trannys

A nv4500 is a sm465 with overdrive a nv3500 has less oclf an overdrive with like. .78 vs. .73 for the 4500 its also stronger as said there is a adapter for the 4 speed to the 5
