    I used to regret that i got a Sm465 b/c i sucked at driving stick, now im better and I am VERY thankful that i have it!
    I ws on the traila nd it was pretty muddy and i fell in some 40" ruts. In 4low and 1st i spun my tires. So i just stuck it in low lifted off the clutch till it caught and it just crawled out. Amazing! =D None of my buddies w/ auto could just crawl out, they just spun their tires =D

    I loved mine too. I HAD to keep the low gear when I went with a new trany, so I went with the NV4500. I also added a gen 2 doubler behind it. If you can do this, I highly recommend it! I can walk up about anything!! 115:1 in 1st gear and doubler low!

    Manual tranies rock!!! Autos are perfect for the afternoon commute and getting groceries!!! (just kidding guys)

    I'm just a big fan of the grany gear that the SM465 and NV4500 have!

    6.34 (1st gear) x 3.96 (double low) x 4.56 (gears) = 114.485 or 115:1 crawl ratio.

    Float stuck in the "full" position going up a pass in Oregon last weekend. (meaning no gas in the carb) I was able to turn the truck around with the starter easily, thanks to low gear, to get the nose pointed down hill. Again, thanks to the SM465, I was able to coast downhill in 2nd, pumping fuel against the stuck carb needle, until the fuel pressure freed the needle, and compression started it...so even HAD I killed the starter moving the truck, I coulda still started it. Lets see ya do that with a 700 :)

    There is a guy at work that has a 72 K5.
    Just today we were discussing "the better tranny"
    He has a BBC/ TH400 and 38.5x11 boggers on his.
    he told me that his rig has been down for 2 years cause of the tranny blowing up and to do it "right" it will cost him mucho denero to fix it.
    I like my 465 just fine. [​IMG]
    I have gotten pretty good at bangin gears in a hurry.
    BTW he blew his tranny towing another rig 6 miles in reverse in the snow at 4-6grand.
    And still drove the 2 hrs home.
    I am the 4th K5 owner at work and the only one with a puter.
    But I have spread the CK5 news. [​IMG]

    Your Friend needs to find a new mechanic, Chissle some of the concrete off his right foot and buy a tranny cooler. Parts to rebuild the TH400 is about $150 including a rebuilt converter. Other than a shift improver kit there is not much else you need to do to them. He should be able to get that tranny rebuilt for $400 if he removes it himself.

    It's not my damn planet monkey boy!

    When I took in my 400 out of my pickup it cost me $860 to have it rebuilt. There was one other place that did them way cheaper but they had a crappy rep.

    Usually I don't try to crawl out of anything. I don't know what kind of surface you were 'wheeling on, but where I go, spinning your tires is how you keep moving. "Crawling" is completely out of the question, no matter how big your truck is (two of my friends have 44s, others have 38"+ tires too)

    BFG tires work well though, don't they???

    I have an auto now--I'm swapping it for an SM 465 ASAP. As in, as soon as I can get the money for the clutch. I've already got tranny/transfer in the garage.

    There's a local guy who advertises in the Nickel Ads that did a good job for me that does them for under $400. I can probably find his card if you're ever in need of another rebuild.

    Crawling is a must here. (or at least some of us recognize that fact)

    Just last weekend (same one on the trip) I did some scouting for hunting season. Idiots out wheeling in an area (Not illegal there yet, but the Forest Service doesn't like people making messes and tearing stuff up) where we hunt, using a route we use to cross a creek (bridge wiped out years ago) spin their tires climbing up out of the creek crossing. Not only is it unnecessary (4lo, tranny lo, low rpms just slowly climb out and up the incline) its also a great way to have areas shut down for silting up streams and ruining wildlife habitat.

    I understand you run in mud, so spinning tires makes perfect sense and is necessary, (so I'm not saying not to do it) but on public land out here, doing that (and dumping trash) will only get it closed down.

    I agree, I love my SM465, its one of the best mods done to date. I will save money for the Gen2 Doubler soon. I bought my SM465 and NP205 cheaper than it costs for a rebuilt Auto.

    Next mod on my list is a hand throttle and some minor cosmetic changes (rocker skids). Tim, we are planning a Potosi trip for this fall, Potosi is located about 1 hour south of St. Louis. Think you coud drive up from Tulsa? Thats what overdrive is for!
