Which is the smallest and lightest 13 speed ? 10 speed ?

I just tried looking at my post with pictures included in Internet Explorer, I get the red "X" as well.

I use MoZilla Firefox at my son-in-law's recommendation (he is a programmer for Rockwell) and it works fine there. Must be a setting on Internet explorer or some kind of issue between Firefox and I E.

No doubt you're right. With this new but used computer every time I linked onto something the link page would be in a small window instead of full sized so in my infinite wisdom I downloaded the latest IE 8 and when my wife got home from work she informed me with a sharp tongue that was a stupid move. She said everyone hates it, plus for the last 4 days after being on TDS for about 15 minutes, when I go to click on a post the computer locks up and after I restart I find I'm not longer logged in here. Big-time fun.

Sorry to get off topic.

There's the ZF Ecomid 9 spd 9.48-0.75, up to 960 ft-lb. 33" long including bellhousing (SAE #2 I think), 420 lb. Not much heavier than a NV5600. Also their Ecosplit 12 and 16 spds which are ~660 lb and 36" long including bellhousing (SAE #1). The transmissions are all synchro. Ecosplit designed for remote shifting with air; Ecomid shifts with stick and range lever (probably needs air source).
They all can be bought with automatic shifting, never need to touch the clutch pedal. My Unimog has that system, it's great even though it's just an 8 spd. I'm sure you pay $$$$ for them.

f450 ford put one in .. If its a 7.3 a rt510 rt /rto610 rt /rto 613 rt/rto 6610 rt/rto 6613 well work go to truck parts look for a s a e flywheelmhousing an fly wheel an a startor an a clutch all the set up from a IH truck 444 well work on your 7.3 motor... If you u p a rt610 or rt613 you can make it a rto 610 or rto613 6610 an 6613 same ..... All motors that has a sae flywheelhousing all eaton fuller roadruner trans will work 5 spd 6 spd 7 spd 8 spd 9 spd 10 spd rto9513 is a big trans but you can get a rtoo9513 with 2 ods rto is od rtoo is 2x od the rtoo 9513 will be a lot work on the truck just do it you will love it 1s with clutch no more clutch till you stop an clutch to put it in gear to go rpm an speed up or down old truck driver real drive with no clutch drive safe driving you no your #1 when you see this yes i am #1 yes yes #1 mike

My favorite Roadranger is the 9LL, 11 spds from 26:1 to 0.73. I'd like to see it with double OD.
RTO-16909ALL.
In a 6X6 Western Star with super singles and a camper?

What's killing your tranny? Heat? Can you provide better cooling?

Anyone done this before?

I just lost my second 4R100 in my F450 and am thinking about going manual. Not sure if the standard 6 speed be strong enough: My F450 weighs 11,000 and my loaded horse trailer weighs around 15,000. The mountains out here in the Pacific NW are Transmission killers. I would love to have a 9 or 10 speed but my guess is they are too big to fit. Maybe a 5 or a 6 speed from a MDT.

There is also the option of putting a regular manual 5 speed up front and then dropping a 3 or 4 speed brownie in behind the thing and going twin sticks, like I did I have the zf5 up front and a 5831b spicer 3 speed brownie out back , it gives me 15 forward and 3 reverse, essentially it gives me a full serious deep reduction range for the whole works then direct and over splits for each gear. I always have exactly the gear I need for the situation to keep the engine where it wants to pull at max power and economy . Don't have to shift it all the time, leave it in OD mostly and just start splittng when I hit steep hills and when I have to tight manuver the trailers or on a long run when the wind dictates selecting something else .
You would not want one of those heavy twin countershaft trannys behind a mid range diesel. They weigh too much and would such up too much torque

The 6610 is supposed to weigh 367 pounds. The 6613 weighs something like 500 pounds. Don't quote that number. Its heavier because it has 3 ranges instead of 2 and the bottom range is double reduction. It doesn't shift like a regular 13 speed. Or so I am told.

I have a special project in mind for a modified 610 or 6610.

I have seen these transmissions in quite a few older crane carriers , the 610 is single countershaft main single aux, the 613 is single shaft main but the aux looks like a twin counter like a 9513 I might be able to get tag numbers but that would take a while . these transmissions would be way better than the pickup stuff in my opinion A lot of these applications had single disc clutches

I didn't know they made the straight 10 speed or 13 in a single countershaft. i knew the earlier compound 12 and 16 speed trannys were single countershaft, but those were just essentially a main box with a brownie mated to it.
Big question is, could a 10 or 13 speed be adapted in and still find a flywheel that would mount to the engine that would accept the appropriate clutch with the clutch brake ? Otherwise the entire thing is moot because you won't be able to get the blamed thing into gear at a stoplight and at certain other inconvenient times . That pesky little clutch brake , you don't think about much, but there are a few times that that little critter you pretty well can't do without with straight cut gears.
