I cant float gears on my t19 how do you all do it like dave and star ? I can float every gear on our 97 cummins 5 speed with little trouble at all .. I have a t19 and when I try floating them all I get is resistance

 

ive never tried it in a pickup, but you cant have any pressure on your clutch. Thats about all ive got to offer.

 

The t19 has synchronizers dont it?

 

I've been forced to do that as my clutch system has not been working properly lately.

If you're getting resistence then the input shaft does not match the speed of the gear you're trying to go into.

For upshifting, pull it out when you reach the top of the lower gear, then apply light pressure on the **** towards the next gear as the RPMs drop. When the speeds match it will slide right in. Do that for a little while and you'll be able to do it smoothly soon enough.

For downshifting, do the same thing but you have to rev it up while you're applying pressure.

 

I never tryed floating down the gears in a pick up. I always double clutch it and rev match when downshifting. Normal clutching or floating when upshifting is my usual habbit.

I started regularlly floating gears in my old '75 K Walker W900 with a 15 speed.

I learned to float gears in my first rig, a 1966 Mack gasser 5 speed and 3 speed brownie. Drove that sucker for 5 years! Bought it when I was 18 in 1975, drove till 1980. Then bought my K Walker and had it for 2 years till 1982 when I quit trucking due to having a family and took up as a city bus driver. Been at it ever since.

 

alright so it is doable ? I dont have a tach on mine but i think i can figure it out now with a lil practice.. unless anyone else has some tips ?

 

Yes it is very doable, I do various things depending on the situation, double clutch, no clutch, clutch it out and sync it in or pull it out and clutch it in.

The condition of the syncros also matter. I can float gears in our only stick shift truck (diesel ranger), but thats an older transmission and can be cranky sometimes and I just end up grinding them. Seems to work better at lower RPM.

My electric car seems to have a healthier transmission and since it has no clutch, gear floating is the only way to shift up or down.

 

I've never had any issues floating a T19, match the rpm and it slides right in no problem.
Now a ZF, it will supposedly kill the syncros in, same with a NV4500, and those are not cheap parts in either one.

 

I've been floating my ZF ever since I bought the truck new in 1990. Never had a problem with it. Probably thanks to that, i'm still on the original clutch.

 

I won't say I don't do it... I just won't reccomend it to anyone else as it could cause some expensive problems...
The ZF6 in my old super pig shifted better without the clutch than with...

 

I seem to only use the clutch to start from a stop, and to start in reverse.
Here's how I started learning with my T19. I actually started by cheating, and the snyhchros allowed me to cheat to learn the process.
I don't have a tach either, so it's all guesswork on the RPM's.
Start out in first gear, let the clutch out and run it up high past where you would normally shift. Let off the gas quick, and pull the shifter out of first, and pull it down towards second. It won't go in right now, it will eventually go in when the RPM's slow down. When the travel speed matches the RPM, the shifter will just drop right into second.
That's not the correct way, but it will get you started.
That's the same procedure for all the forward gears.
Eventually, you'll time it just right with enough practice.

For downshifting, I engine brake until 4th gear isn't slowing me down too much. Around 35 mph typically. Then I gently tap the gas enough to pop the shifter out of 4th gear. I rev the engine and gently push the shifter into third, it won't go in yet. When everything speed matches, the shifter pops right in. Then, let off the gas and continue engine braking.

That's a procedure to get you started. It's sloppy, but with enough practice it'll get nice and smooth.

 

like he said, just keep the pressure real light and you wont do your syncros much harm

 

Shift the ZF5 in the 91 all the time without a clutch, no problems yet... I've also been shifting gears for ~45 years!

A T18/9 is an excellent transmission to learn with.

Also the smaller the gears the harder it is to do.

Smooth is what it's all about, with or without clutch, learn to shift so smooth the only way one knows you shifted is by the difference in RPM... It shouldn't be felt!

Practice Practice Practice!

lol oh im smooth now with the clutch, its pretty sweet, but ill practice floatin em more I wanna prolong the clutch as long as possible .. thanks for all the tips !!
