Dual Transmissions?!?! It's truely a work of art!

wow.. just wow.. lol

wow thats pretty slick.......some of the old power king garden tractors had dual transmissions..not sure how they were set up tho....

thats crazy.

Wow !!! Some of the things people can do when they've got the resources.

I know right and if any of you read down far enough this setup combined with his transfer case gave him a crawl ratio of 300:1!!!

And for those of you who don't know a 300:1 crawl ratio is just retarded!!!! The NP241 tranfer case has a stock crawl ratio 2:61:1 which means in 4lo you can get upto about 25 miles per hour... Now with a ratio as high as 300:1 if you had a 4spd trans you could shift thru all 4 gears and walk beside the vehical in 4 gear!!! Simply Ridiculous!!!

i bet its a climbin sob

How did he come up with 300:1? My math doesnt add up.

3.06 X 3 X 2.61 X 5.72 = 137.05

hmm.... 5 speed from a 84 chevy c4500(kodiak) and a 465..... thatd give me some serious gear choices i think i'd visit my buddies machine shop and have a custom transmission housing built rather than trying to couple the 2 together.... but then if im gonna do that, and deal with that kind of weight, why not throw in a 12 speed browning trans.... then i could have 2 ranges.... i think ill save the 2000 dollars for the metal in the custom case, and pay a few hundred for a 203/205 doubler..... but that is a neat idea

Ok so I reread and this is what I found... He made a dual manual setup too... The quote below was the manumatic setup

Crawl ratio of 160ish:1 + whatever you allow for torque converter slip.
I wheeled this setup several times and drove it on the highway in overdrive quite a few times. It worked amazing on and off road.

However.........

And this is what he says about the dual manual setup!

Haven't wheeled the dual manuals yet, done a lot of street driving befoire I stripped done the rig. In an open lot, I could stand beside the truck, with both trannies in neutral, shift them into first one at a time, through the window (with the t-case in neutral) and continue to shift one of them through 2nd, 3rd and 4th, all through the window walking alongside.
Crawl is around 400:1 in reverse/reverse

That is actually a very old idea. It has been done many times before way way back in the days, even before my days really. Although, not in a 4x4 and not behind an automatic trans. Its been done where guys had both transmisisons divorced, using a bolt on yoke connected by u joint to another yoke to be the coupler and the 2nd transmisison was installed backwards to be used as an overdrive unit. Done with a 3 speed manual trans, your 3rd gear would give you a 1 to 1 ratio, and 2nd and 1st gears gave you 2 differant overdrive gears. Its not a bad idea, but it rarely lasted a long time because of the angle cuts on the gear and working in backwards of the gear cuts. But if you were to find a straight cut gear transmission, its sure alot cheaper than a gear bender unit.

Huh... That's really an amazing concept... See until this thread I'd never heard of dual transmissions. I've seen dual Tcases but not trannies!
