    Yep, drove my truck for the first time in 4 months a few minutes ago. Battled a small electrical issue for a few hours, found the plug for my glow plug circuit was a little shaky. Didn't have enough slack the way things were routed...

    Fixed that and she fired up no problem! :waytogo:

    My sheetmetal work leaves something to be desired, the new tranny tunnel vibrates like a cheap motel bed at idle. :doah:

    First thing I found out was my clutch wasn't releasing properly...so I hopped out and adjusted it out some. Then to be somewhat safe I moved the van out from behind the truck and tried it again. I was able to get it into reverse with no drama...but the release point is right at the floor. I suspect there is still a little air in the hydro clutch lines.

    From there I took it for a quick spin around the block.

    First impressions...damn do those Alcan's ride nice. My Jimmy rides smoother than our Montana does now. Secondly, the NV4500 is a much smoother shifting tranny than the SM465. Never got it out of third though.

    Last thing I discovered is the freshly rebuilt 203 range box likes to jump out of high range and into neutral when you let up on the gas. I did a search and found I'm not the only one that's had this problem when going doubler. Apparently the fix is to add a 1/4" shim under the shifter detent spring. I'll be doing that later or tomorrow.

    All I have left is to bolt up the extended front brakelines, front shock towers and Bilstien 5150's, deal with the tranny tunnel vibration issue and throw the hardtop back on. I see light at the end of the tunnel!! :D

    Well, this was the fix that FWP came up with...but I will update and let you know if it works for me. It can't be anything else, the entire case is new, the shifter doesn't hit anything and nothing is loose. It stays in low range just fine...

    As am I!! Soon, I just want to drive it a few weeks to get all the niggling issues taken care of, then it'll be time for some wheeling (in the worst weather of course)

    Sounds sweet. Have you driven it with that crawl ratio yet? I can't wait to try mine, the numbers are coming out at 105.2:1, should be a nice change.:D I haven't driven my truck in a long time either, but I think it's been about 10 months. :eek1: :(

    Nope, I didn't get much time to mess around with it due to the weather. I still don't have the top back on the truck...I got a little distracted by the 203 popping out of high range when I was driving it.

    I should get the hardtop back on today, and then I'll go out and play with double low. :D

    You figure out why the 203 popped out of high? I hope that's not some inherent affliction of the rangebox.:crazy:

    Well, I did do a search and came up with some interesting info.

    Thread i found: http://coloradok5.com/forums/showthread.php?t=57309&highlight=203+shifting+problems

    Looks like the detents aren't very deep from the factory and the spring isn't very strong. I think the theory here is that the factory shifter helped keep the 203 in the correct range, but with these 'stand alone' 203 shifters often the stock spring and detent isn't enough to keep it in high range.

    I will be trying Fred's 'fix' of adding a spacer under the detent spring.

    Sweet, thanks for the info. It's good to see that at least one of the fixes is doable without dropping the case. I wonder if I should take my 203 back apart and grind the detent bar since it isn't in my truck yet. :thinking:

    I used the head of a 5/16" bolt with just enough stub on it so it would spigot on the bottom of the spring. I'll update once I drive it again. It wasn't that hard to get to...

    I wish i had a few more, but they're like d60's. spendy and not so easy to find. I got this one from another CK5er for free about 5 years ago...but it was a basket case. It needed a bunch of parts like an input gear, countershaft and all new synchro's, bearings and seals.

    did you ever take pics of your 4500 when it was all done?
    like the transmission tunnel and stuff :)
