Help driving a 1964 f250 4 speed with granny gear

Hello all!
I'm a total newbie to this site and old trucks (or cars). I'm planning to post soon with information on my "new" truck and some photos to get advice.
But...i think I need some help sooner rather than later.
I drive a manual everyday but it is a 2018 and shifts soooo easily. This 1964 is a whole different beast and I can't figure it out. I know first is granny gear and to start in first I have to give it a lot of gas. But starting in second I just keep killing it.
then when driving and trying to shift into second it grinds the gears and won't go in. If I have to start in first should I then just skip second? But when I tried that (because I couldn't get it into second) it felt like I wasn't at a high enough speed for third. When I get going third feels good but I have only been doing trips around the block and haven't even tried fourth yet.
So, I'm sure I am doing something horribly wrong but I just can't quite figure it out. If any of you lovely people could give me some classic medium duty truck driving advice I would greatly appreciate it.
Thanks!
ps. I'm pretty sure it is the t98a transmission but not 100% on that as the transmission code is the only thing missing off my warranty plate.
So probably not the t98 since it is missing the code and is a special order

Warranty Plate TRANS code F = 1961/64 Borg-Warner T-98 4 Speed. Look closely, because the F may be mixed in with the previous BODY code or the following AXLE code.

If there's no TRANS code, the DSO code will contain 6 numbers denoting a Domestic Special Order. This means that whatever trans was installed was not an RPO (Regular Production Order).

So, it will not be a T-98 that is synchronized in 2nd/3rd/4th gear.

Of course, by now, the syncro brass blocker rings are probably worn, so the trans could grind in any gear. Double clutching will solve the problem, that is if you know how to do it.

Yep it is a special order. I wasn't sure that the missing trans code meant that the transmission was the reason for the special order. I'm working on cleaning it up as much as possible to get parts numbers and waiting on a few books to identify the transmission.
the only other information I have right now is that it is a double h according to the seller. With granny gear first at upper left, second below, third up to right, four below, reverse down to right, and another first gear above reverse.

When shifting don't rush or force it. When going from 1st to 2nd just kind of pop it out of 1st and then easily go to 2nd. I find if you don't try to rush the shift it goes a lot smoother. These are definitely not sport cars.

So how do the two low/first gears compare? Sometimes on my 4 speed, if it seems like it's hard to shift into the next gear, I will let off the clutch for a moment and the depress it again. Seems to help, but mine rarely acts up.

I have always consider 4 speed as a 3 speed with a compound low 1st, which rarely if ever use.

Thank you all for replying!
From your answers so far I have realised that I need to just find a way to get it going in 2nd since it is really my 1st gear for regular driving and I'm not doing myself any favors staring there. I need to slow myself down a bit when shifting instead of expecting it to respond anything like the manual I drive now. and I might be helped by double clutching. Which from what I can gather is: depress clutch and take out of current gear, release clutch, if upshifting depress clutch again and shift into new gear or if downshifting depress clutch again give it a bit of gas and then go into lower gear.

And if none of this works I'll just drive in reverse all the time because that gear is weirdly very smooth


I finished cleaning the bottom of the assembly and I'm attaching a photo in case a guru on here can identify it for me since it will possibly not be in the manuals if it was a special order.

Once you get the hang of it it's a piece of cake. Or do what I did and drop an automatic in. I'm a lazy driver.

From the Vee shape of trans and shift pattern sounds like Clark 5 speed. There is 2 provisions for pto s ? The 2 Clarks I have has reverse up to right ,1st down to right, 2nd up to left,3rd down to left with 3rd/4th in middle. May be tag on other side with model #.

Clarks could have multiple shift patterns.

Should be a tag on the tranny - find it and post the info.

As for shifting, I would fill it with 80W90 or even 85W140. Some may think I'm nuts, but this will help make up for worn synchros.

If you have any friends that drive truck, ask them to take you for a ride in your truck and have them teach you how to shift without the clutch and how to double clutch it.

That's a medium duty transmission, notice the parking brake flange? Also notice the bell housing mounts. That transmission is non syncro. Find. Find a tag or number on it. But you are going to have to rev match every shift like a semi.

Bellhousing mounts were standard up to '64 on all Ford pickups as was the parking brake flange on many of them.

I stand corrected, I really need to slow down and see the section I am in. Could have sworn the thread was in the 67-72 section.

Hey all. Thanks for the help so far!
We drove it to a mechanics shop today to get a list of all the things they found wrong with the truck so that we can pick one item off the list and start learning and try to fix it.
The drive went better today for my husband. He skipped first gear and was able to get it going in 2nd ( I still haven't figured that out) and used double clutching as you all suggested and only ground the gears once on a 15 min drive. I tried double clutch yesterday from 2nd to 3rd and it really helped. Getting better.
So what is this shifting without the clutch?? I had no idea that was possible.
Truck isn't here for me to go look again but we cleaned the under the truck portion of the transmission and there just isn't a model plate anywhere. I found 3 serial numbers on parts.
from the cab I can look through the floor and see 224715 below the shift stick. From under the truck I can see 221408 on a very shiny round plate that faces the rear wheels ( you can see the plate in the photo I posted ). There is one more number but i didnt write it down yet so ill have to post it tomorrow after we get it back.

Also, I wish I had friends that drive a truck but most don't even know how to drive a modern stick
I'm in a city now and if I trusted it to make the drive to my hometown I'd probably have 100 people on the street who could show me what to do but, as it is, I'll just have to figure it out with the advice you guys are giving me and hope I don't do too much damage.
