    SM465 L-2-3-4, can't shift into 2nd unless completely stopped (solved)

    Mtnmankev, gold sticker for you! That works! I've heard about this quite a bit, but I kept getting it wrong. I would have the clutch in, then rev, then try the shift into 2nd (L-2-3-4). Doesn't work. Doing what you said to rev, hit the clutch, and shift works!

    SM465 L-2-3-4, can't shift into 2nd unless completely stopped (solved)

    Have been test driving past few days. Seems breaking it in, gently, and progressively longer trips has been making it shift into 2nd (L-2-3-4) much better. But, still can't shift into 2nd from neutral while rolling above 2mph. Might say I've now put 20 miles on the tranny. Planning to daily...

    SM465 L-2-3-4, can't shift into 2nd unless completely stopped (solved)

    pduffyd, I totally watched all of his stuff, very helpful, got my phone all greasy pausing his video during my work. So, update, I have learned the 2nd syncro hub and low gear can wear each other in normal operation. Both of which are original on mine, hence the gap, ah ha! The low gear thrust...

    SM465 L-2-3-4, can't shift into 2nd unless completely stopped (solved)

    Tonight had top cover off. So nothing super obviously wrong initially. I did notice the 4th gear syncro ring seemed tight against the input shaft/ gear. Although it would still move left and right so not seized. Had a helper rotate output yoke, and I noticed when I disengaged the clutch the...

    SM465 L-2-3-4, can't shift into 2nd unless completely stopped (solved)

    I was using the naming L-2-3-4, and using Redline MT-90. Getting into the synchronized 2nd (or by your shifter pic 1st) is the tricky one after the full rebuild and clutch job. Until I take top cover off (tonight), I'm going to chalk it up to stuff is still tight, maybe the new solid pilot...

    SM465 L-2-3-4, can't shift into 2nd unless completely stopped (solved)

    Shorty81, thanks for some reassurance. I've heard about that. I've tried crawling in my driveway too and I can't get it into 2nd. Only dead stop right now, and it still takes some fiddling. I've only put maybe 5 miles on all the new hardware too, so wasn't sure if it's tight stuff causing...

    SM465 L-2-3-4, can't shift into 2nd unless completely stopped (solved)

    Want to add synchronizer hubs and associated springs and keys are the originals. I wonder if there are some wear features on the 2nd hub that's catching a nice fresh slider on...? I think I need to take the top cover off and take a look...

    SM465 L-2-3-4, can't shift into 2nd unless completely stopped (solved)

    1983 C30 2wd. To set my SM465 gearing naming I'm going with L-2-3-4. So, just completely rebuilt a SM465: all new bearings, synchros, rebuilt top cover. Also I replaced main shaft, input shaft, 2nd gear and slider, 3rd gear and slider, reverse idler gear. I'm using Redline MT-90. In addition...

    1981 C10 stock parking brake pedal not staying down

    The stock parking brake pedal won't stay down anymore. I suspect it's a weak spring holding a locking lever to a geared cam type thing. Is it best to take the whole thing off and do a rebuild (any rebuilt kits?), buy a new aftermarket parking brake pedal (although I imagine the fit wouldn't be...

    MSD box and external coil (looks flashy) vehicle inspection risk

    Anybody in Williamson County TX try and inspect their truck with a MSD box under the hood? Was your MSD box plainly visible as well? Looking to throw my MSD 6AL box and external cylinder type coil (Blaster 2) into my 81 C10, and wondering if it would raise suspicions during an inspection?

    Clicking coming from engine bay

    Exhaust manifold leak to me. My 305 sounded like that when I first got it, used, put on new mr. gaskets and new ARP manifold bolts, now quiet and fixed. Since it ticks I suspect its leaking at one of the exhaust ports. I haven't tried this and don't know if it would work but you could maybe...

    PCV valve rattle when running

    So the PCV grommet was petrified when I went to go remove it. I ended up grabbing a MPF 39210 PCV valve from Napa and a new grommet. After I put these two on the new PCV did not rattle and the PCV was held much more securely in the new grommet. As a result my previous idle flutter went away, and...

    PCV valve rattle when running

    81 C10 305, long tube headers, no EGR, no TVS, 4 bbl Edelbrock 1406, aftermarket aircleaner, 8 deg base adv. I've noticed ever since I put a new PCV valve on one of the valve covers it rattles like a machine gun when running. I have a new breather cap on the other valve cover. Is the PCV...

    Catalytic converters: does your square have them?

    So, Austin (williamson cnty) can be tricky it seems. I am in the process of getting my 81 C10 inspectable and no cats (current status) got me wondering... Also, I don't have the stock air cleaner, no EGR, long tube headers, no TVS. I've had people say if they look under the hood they are taking...

    Suggestions for single/dual elec. fan shroud for stock 305 ci radiator?

    I have a aluminum flex fan mounted directly to my water pump pulley, which I know is common and perfectly fine, but I'm looking to go electric. I'm contemplating going the super simple way and just mounting an elec. fan onto the radiator, but I'd like to think a shroud would be more efficient...

    Hello from central Texas

    Hi, I have a small collection of vehicles including a 1981 C10 shortbed that is currently my highest priority fix right now. I'm not looking to flip, I'm just a backyard mechanic that likes horsepower, speed, and engine growl!
