Engine/Transmission (1994 - 1998) 10 speed trans. ??

[bnelson]

Anybody out there put a 10-speed roadranger behind a 12-valve in a Dodge?

 

[KBurgoyne]

what are you gonna be towing. them things are rated for 100k pounds. they also make 5 and 6 speed medium duty transmissions still rated for 33k. it would be far easier and cheaper to put a built ZF in.

10-speed

I know. I've had experience with 9 & 10 speeds in big trucks. Just sick and tired of the NV 4500 needing so much major attention since I rarely tow anything. Now it appears that the splines under the 5th gear have gone away. This is with the fully splined mainshaft less than 100,000 miles ago.

The RT/RTO610 is small enough, but the #2 bellhousing is a bit large, you will need a small body lift.

Just a quick thought,



No harm in wanting to better your rig but a 6-speed Fuller might be a better choice, I don't know if you would be happy with a 610.



It would be like rowing a boat with a short paddle and your arm will get tired... ..... .



The 610 is different that it's bigger brothers. The range between gears is funky in any that I ever drove.



Plus the 6 speed won't need an air supply.

Mike I don't think air supply will be a problem since he has air ride seats.

A ten speed would be sweet loaded, but IMO would flat out suck empty.

What kind of problems have you had with your current trans? (other than the current spline issue)

 

[KLauber]

Spicer 7 speed? Probably too big as mentioned before... .

G56 out of a newer truck? Jus' saying'

RE: 10-speed

After the fully-splined mainshaft went in I lost some teeth on 3rd gear. just opened it up for the current problem and I find teeth missing on one spot on the 5th gear on the mainshaft plus most of the teeth chipped on the countershaft 5th gear, these on the rear of the truck side of the gear. I was running up Cabbage hill east of Pendleton, Ore. when this occurred. Empty, 5th gear about 55, just cruising at about 1700 RPM. No "Ford beside" or anything like that going on. I have pulled sleds before but that was not in 5th gear. The sled pulling may have had something to do with the previous 3rd gear deal since 3rd and 4WD-low was my pulling gear. Mike, at Mike's Transmission at Ephratra, Wa. mentioned that none of the aftermarket mainshafts are USA made and it appears none of the other parts are either. Mike thought inferior quality steel from offshore was the cause of most people's problem with repairs and overhauls lasting. This is about to affect my vocabulary improvement program adversely. #@$%!

Skip gears when you are empty

As I recall the little 610 and 613 Fullers were used with Gasoline or small V-8 Diesels such as the 3208 Cat. These engines all turned 3500 rpm at least.



When you put one behind a slower turning 6 banger it makes the shifts empty quite mean, and it will almost bind even while trying to skip gears.

It is driveable, just not as smooth as the bigger 10-speeds would be.



Also any that I drove had the little air button for the clutch brake so you had a half a chance of getting it into gear... . I don't know if that was someone's better idea or if it means you can't put a normal clutch brake in there. I would want to know that right up front before I installed one or you would have to shut the motor off to get them into gear. They were awful without a working clutch brake.

Mike!!! quit bringing up reasonable facts to not have one..... I want one in my Ford:-laf

Empty, 5th gear about 55, just cruising at about 1700 RPM.

If you do much of that then you have your answer for the 5th gear failure. Gear down or speed up is the only solution.



A heavy duty 4 speed with a 2 speed box on the back would be a better solution but fitment is still an issue as is toughness. Trying to find light duty parts that will withstand the assault form a medium duty engine is just problematic. The big twin countershaft transmissions are great but even then all the gears are under 1:1 when we need a couple more over 1:1 for efficiency.



If you like shifting, LOTS of shifting, then the medium duty units are the way to go but its a lot of work to match things up.

Rowing is heaven....

A 13 speed Roadranger is the answer, LOL!!

I could make a crack about a parts man here but I won't.

Your thinking is right in line with mine as to the operation of the trans empty. Don't get me wrong, it would be super cool, but a handful.

To the OP have you thought of converting to a 5600? It's no MHT trans but it is the pick of the litter as far as "bolt in"

It's actually "Truck Driver/Mechanic turned Parts Man"... and not really all that good at any of it sometimes... ...



Not always such a good background to have... . :-laf



I deserve a crack after missing that little detail in his signature... .

[EMAC2]

Anybody have a pick of the road ranger already installed?

 

[Barry]

Stay away from the Spicer 7 speeds... ... ..... they were junk when new.



But I have fond memories of the little 2 and 3 speed Brownies... ... ... wonder how hard it would be to find one?



You could get the Brownies in a variety of ratios. My favorite was the 3 speed in under/direct/over.

Do a search on youtube or dieseltruckresource. It has been done by a few people who seemed to be pleased with the results. There is a video of a mid 80's chevy truck with a 12 valve cummins on youtube that sounds awesome splitting gears.
