Installing The NV4500 5 Speed Overdrive Transmission In The C-30

[jumpsoffrock]

In May I bought a used NV4500(1993/94 GM version), and was told is was good and useable. I finally got it "installed" in the truck about a month ago and finally finally got a driveshaft made and installed a few days ago last thursday.

I installed it by drilling holes using Leons method. I did a very poor job, but it worked.

The trans is bolted only using 3 of the 4 bolts, tightened with a combo wrench.

Filled with Amsoil MTGQT-EA.

It ran fine, I just wanted to drive it through the gears and specifically into 5th, no grinding, ran good, and I can proceed with other work on the truck knowing it *should* drive fine for the time being.

Thank you Leon.

No problem. Glad you got it dialed in. I don't know which bolt you had trouble with but I would definitely try to get it installed. That trans weighs close to 200 pounds and needs all of the bolts in it if possible.....
