Wonít go into first

Hey all,

Iíve got a 1970 with a 302 and 3 speed. Been driving the truck around for a few days now, and it will not go into first unless Iím basically completely stopped. Maybe this is normal, Iím not sure. The problem is if Iím say turning around in a culdesac, the engine starts bogging out and bucking Because itís still in second. It goes thru all the gears while stopped with the engine running no problem.

According to original operators manual, first gear is only down shifted at 0 mph. I don't fight it, but can get it into first when rolling just a bit, so what you're saying regarding down shifting is normal. Generally speaking you should never down shift any stick to first unless stopped.

At real low speed in second give it a bit more throttle and slowly ease up on the clutch. If you do that and it bucks you've got a different issue.

You can always "double clutch ". What we did with trucks with no synchros.

What they said basically. While it is a synchronized gear, it's just not set up for easy downshifts while rolling more than a couple of miles an hour.

It is doable though, as with just about any manual transmission you can double-clutch it after giving it a bit of a throttle blip.
Doing this with some of these transmissions will not let you downshift at 15mph or anything like that, but with some you can get quite good at downshifting maybe as high as 8-10mph when in need.
Just takes practice, like anything else.

In fact, if you don't know how to shift without the clutch you should learn. It's an acquired skill, but can come in very handy when your stock clutch rod snaps in the middle of your commute!

And speaking of general maintenance... When was the last time the transmission was gone through, or had the fluid replaced?
This can actually make a difference in some gearboxes. Didn't make a huge difference in mine (but mine was pretty well maintained anyway) but in some it's practically a shifting-miracle!

Thanks for the input Paul. This is my first manual vehicle (I’m 18), so maybe shifting clutchless is just slightly out of reach still . I’ll give the double clutching a try tomorrow and see how she goes. Fluid was just replaced in both diffs, the transfer case, and the transmission.

Perfect! And there's no time like the present to learn.
Even though I "knew" how to do it, from watching and learning from the old-timers (my dad) I didn't really master the clutchless shifting until the day my linkage broke on the way to work!
Mainly because I just had not practiced. And the few times I did I did not like even light grinding (a little really does not hurt the trans. Just your senses!) when I messed up.
But after that I felt I could shift anything, any way, any time.

So don't rush it, but don't shy away from it when you have time to mess around.
You familiar with the double-clutching process for downshifting? If not let us know and I'm sure a bunch will chime in with their exploits over the years.

And don't go crazy with the Bronco either (says the old man to the young man ) since you're still a "relatively" new driver of only a few years now, or maybe only a couple, these Broncos are not bad drivers for what they are, but they are still 50 year old technology that needs to be treated that way.
Especially when just learning about them!

What's the overall shape of yours? Good brakes? Not too high? Normal stuff is in good shape?

Have fun!

You’re definitely right. Might as well learn now! Haha. My pops explained double clutching to me and when I told him y’all said the same, he was pretty happy with himself haha. I put in power steering, hydroboost, and a 2.5” lift. It’s on 33’s. Perfect height right where I want it. Any higher would be too much for me I think. I replaced a lot of the brake lines and did all new bushings up front. She rattles and shakes here and there but again, like you said, 50 years old! I made sure that the brakes and steering are perfect, and most other things are a work in progress.

Hi, if the clutch is grabbing to close to the floor, or to close to the top, it is out of adjustment.
The clutch should grab more in the middle.
If the clutch is out of adjustment it will magnify this issue.
Good luck
