Make sure you don't push the clutch pedal all the way down, except when going into a gear from a stop. Will cause excess wear on the clutch brake. The lining on them is VERY thin. If it is adjusted tight enough, you can actually stop the truck with it.
 
Goin' much better. Downshifting is still a pain. Do you just down shift the higher gears, or go all the way through the lower ones as well?

I usually just slow down with the truck in whatever gear it's in and pop the transmission out of gear when the motor gets close to idle speed. If I'm slowing down with the jake brake I will keep downshifting until I run out of room and have to stop with the brakes.
 
there is about 600 rpm split between gears work hard on double cluthing so while you are learnig won't be so hard on clutch and transmission more gears less spilt fewer gears more spilt ie 13spd 400 rpm 6 and 4 i will come teach you myself if truck sharpe and fast

like maybe 85 359 pete about 300 inch wheel base lots of chrome

I generally don't go to the low side. Just depends on the situation.



You should never coast out of gear. Especially when still learning on how to shift. If for some reason you need to hammer down to prevent being rear-ended, or other-wise get out of a sticky situation, you'll want to be in gear. If you get rushed, it may make it hard to catch a gear.
 
I'm curious if this was a straight bolt on application or was there some modifications to bolting that puppy up. I am very tired of my long winded 5spd and want better gearing. I have a 13k fifth wheel and would like to get away from the 5spd. Having more usable gears would be better on the engine and having smaller steps would eliminate having to pull a hill in 4th gear at around 2500 rpm's at 65mph.
 
Going from direct (1:1) to O/D (. 73-. 75) is still a bit of a jump on a Eaton. The O/D ratio would be the same, or very close to what you already have in your 5spd. You would want to find a transmission with a double O/D, like a Mack T2130. 12th is something like . 80, and 13th is around . 75. They are heavier than a Eaton, though. And are a triple counter-shaft transmission, IIRC.



A Gear Vendors or a US Gear unit would probably be easier and cheaper to buy/install.
 
I haved looked at the Gear Vendors and US gear and wondered if they really work. How bout some input from those using either that have done some pulling. Pros and cons, not meaning to start beating that dead horse just want some input. I just want to eliminate those long stretches.
 
I work in the shop of a concrete company (jonesandsons.com) and about a dozen of our tri-axles, quads, and tractor-trailers have Roadrangers or Meritors in them. We run Delvac 1300 Super 15w40 in the engines and transmissions. We change the oil in the trans every year and never seem to have any problems with the transmissions--one of them has 1. 3 million miles on it (original trans, 2nd engine) and the driver drives this truck like he stole it.
 
RHarvey,

I talked to a member of the site awhile back who lives over by where the roadrangers are made,(somewhere in the Carolinas) and he says that he just finished up putting a 13 speed ranger in his. He then went on to say that the fuller 9 speed and the 13 speed road rangers will fit our bell housing on our engines. Sorry I can't remember his name. He was on the chat when I talked to him.

I'm getting dizzy from all the reading. I have looked at the US gears and Gear Vendors and I'm looking for something that will give an easier jump from gear to gear when pulling instead of just 5 speeds. I know there is money involved. Bombing is addictive, correct? Will either of the above mentioned or the Eaton Fuller drop a few R. P. M's off the engine when running through the gears, i. e little steps instead of big leaps. With my fifth wheel the jump from 2nd to 3rd to 4th is too long. Those with a 5 spd know this. I wonder what the Roadranger 13 spd would do.
 
Ok checking out the Roadranger website, they have a 6 spd manual. Does anyone know if that puppy will bolt up to my engine. I like the gearing it has and compared to the Dodge 6 spd it looks like the steps between each gear is much better. If I'm wrong let me know, but I think it will serve the purpose I need. Looks like it won't take any off the R. P. M's like I wanted, but the smaller steps are an improvement. I also like the 7 spd as well. Any info is appreciated.

Hey Jason,



Let me know if and when you're ever running I-10 through Indio Ca. I'd like to check out your ride. My mobile is 760-567-8905. Leave a message... .
 
This is not good all ready crunching numbers and the thoughts of floating gears running up the road IN MY PICK UP, it dont get much better than that.
