t19

[timmytim]

Anyone ever had a t19 and ran hiway gears like 3.00 gears? I think the 4spds are real cool in our trucks but alittle too low geared for my truck. If i replace my 370 with 300 or 275 would the t19 first gear still feal like a granny?

Yes. Well, these trucks never came with T-19's, but I guess you're talking about a granny T18 or T19 and the answer is even with 3.00 gears granny is still granny. There are non granny 1st gear T-19's, but the question then becomes why do you want shift one more time?

I know bumps came with t18. What Ive read so far is the t19 is basically same tranny except for two differences. The t19 granny gear isn't as low as the t18 and the t19 is synchronized. My question is if I put a high geared rearend in my truck will I be able to use the granny hole as a normal 1st or will it still be too low to use during normal driving around town.

What tire size? I know my 95 F150 came with 2.73 rear end gears, and an M5OD-r2 behind it. A little more first gear would have been nice. I don't think that using the granny gear would be much of a problem, but I think more often than not, you'd still be skipping it.

Oh damn! Those are some tiny ass tires! I was running 31s on mine. I say go for it! Whats the worst than can happen? use a spare 3rd member for the 9", so if you don't like it, you can easily swap back to your current gear ratio.

There are several different ratios of T-19 used in Fords. The 4.02 first ratio trannies are not granny transmissions. They should be used with something like a 3.00 or 3.25 rear gear and 31" tires. 4.02 is a pretty deep first gear for a light truck so you need to gear it taller than usual.

You can't really do a 1-2 shift with a granny transmission every time you take off. It really beats up the tranny to do this as the difference in ratio from 1 to 2 is HUGE, it's not a progressive step like it is in a close ratio transmission.

hehe what ive been wanting to do is go to bone yard and find a 3.25, around 3.00 and maybe around 2.75. Get those 3rd members and swap them out until i find one I like. Right now I have a fmx auto but I really like to shift my gears. Im just learned that you can remove the trans tunnel hump fairly easy so now Im wanting to swap to a 4spd. When I was a teen I had a dent side and I hacked up the floor to put a shifter in floor. It was one of those 3spd and my floor shifter never worked right and didnt look right either. Shifter was too short and too close to seat.

Thanks averagef250. Ok so the 4.02 isnt a granny gear so I should be able to shift 1st to 2nd without hurting tranny right. I can run the hiway gear rearend and still have a good take off and also be able to run 70 80 mpr right. Thats really what Im wanting to do.

If some t19 are granny and some are not, is there a id tag on trans that i can use to id in the bone yard? I believe the t19 has a pto cover on both sides and the t18 only has one pto cover but what about the grannys

What engine are you running? If I followed your posts correctly, its a 240 which I believe is the windsor bellhousing pattern. If so, why not run an M5OD-r2 from a late 80s early 90s F150? They are easy to come across, and shouldn't be any harder to swap in that any other standard transmission. Plus, since it is a hydraulic clutch setup, you won't have to worry about fine tuning any linkage or anything.

Running the M5OD-r2 will give you O/D, and you could stick with 3.30s, or 3.50s, or whatever rear end gear you want. Win-win. I believe 1st gear in those is somewhere right around 3.90. Its a great run-around-town type transmission, and will shift more smoothly than T-19. At least from my experiences.

Good day Tim,

Long live this thread! I also have a keen interest in installing a ~3:1 rear and 4:1 T19 in my truck, with 31 or 33" tires. I hope you get lots of replies so I can read all about it.

Thank you,
Robroy

Definitely go M5R2 if you can bolt it up. They're great transmissions, pleasant to shift.

Nothing wrong with T19's.

Thats sounding more like that I want GIjoe4500.. Is the shifter location in same place as the factory t-18? So I can just swap the trans tunnel for a 4 spd and it will work with this trans? I love the idea of hydraulic clutch set up.. the 6 is on a small block bellhousing all I do is get a neutral balance flywheel from a 250 6 and it suppose to work. Thanks for the info

[GIJoe4500]

I can't vouch for shifter location. But it shouldn't be anything insurmountable as far as getting it to work goes. May have to relocate the shifter hole, or strategically bend the shift lever, but none of that is very hard.

Also, in the 2wd variety, those transmission only cost about $100. Whatever you do, BE SURE to install a quality, brand new, clutch slave cylinder. They are prone to fail, and super cheap, so you might as well start out with a good unit to begin with.
