Was going to make an entry under transmissions and drivetrains. However, since I cannot access it I decided the next best place might be this build thread. I have been thinking about swapping out my CH465 trans with something more suitable.

I looked at the Tremec 5 speed 4050 transmission 600 lb-ft torque, Max RPM 5500, 23 spline output and would be interested in any feedback or suggestions since I am not fully confident and am a little worried about a huge job making a new one fit.

Is the NV4500 a direct fit to replace the CH465? I like my off road truck, but it is nice to drive on the highway without the higher RPMs when driving 70+.

Electrical / 1986 k10 suburban| bat terminals on fuse block| power in

Hello all,

It’s been a long time since I have posted anything, I can’t remember if I still had my k5 blazer, or my c10. Unfortunately I no longer have the blazer and the c10 was involved in an accident. I ended up buying my father’s suburban from him, and now I am tidying up some of the wiring. He’s bought some powered accessories from a three letter company who I shall not name and there is a bit of wiring mess in the cabin. While attempting to get the radio pulled out, one of those retrofit modern radios, something happened where the fuse block no longer has 12 volts at the bat terminals of the fuse box. The truck still runs, but I would really like to get this addressed so I can run the radio 12 volt constant from the fuse box rather than running a new wire into the truck for a temporary solution, because I have found there is nothing more permanent than a temporary solution.

Sorry, I know you have wiring diagrams posted, but I only have my phone currently than that’s a mess to try and track on it.

Thank You for your time.

Once I get it where I want it, I may try to quiet it down a bit. It is a little louder than I care for as well. Draws too much attention! It it fun to drive and I have thought about getting another transmission for it. I like the standard transmission and would not mind getting one that would easily swap out with the CH465 that would be a good match with my engine and transfer case NP205, plus good for the highway and towing when needed.

Got my first road test of my truck. Short ride! Still have some tuning to do yet and some other things to get it where I want it.

The problem is with the host.  It has impacted several of the forum boards.  The site administrator has opened a repair ticket and is working to resolve the issue.  Sorry for the inconvenience.

I continue to get a Database Error when I click on Engines/Drivetrains and Four Wheel Drives. Is it a forum problem or on my end. Been having the problem for quite a while!

Some easy telltales are the power lock relay will be to the right of the steering column, there will also be a pink wire tapped into the fuse box with a circuit breaker. It will also have the bumped out kick panels to clear the wiring harness.

Thank you
