Helpp super ten will not pull out loaded!

8 LL is a great tranny for that use. i swapped a 13 out for one. driveshaft work, cooler lines to tranny, lucky if you find someone to take a 10 core in for anything other than a 10.good luck to you. johnny

 

The 8LL is good for that but thats about it imo. I drove 1 for awhile and did not like it. The gears are spaced to far apart on the top side. It seemed like when you were in 7th and trying to go up that you could wind it all the way up but 8th would cause it to fall on its face as the rpms dropped off to far. A 15 or 18 would be my choice.

 

A super 10 in a tri axle dump? Who spected that truck!? A super 10 only has a first gear ratio of 10.99:1. That very high. The super 10 was designed for highway trucks. Even a regular 10 speed has a low gear of 12.69:1. The 8LL was designed for this type of app. It has a low low of 14.56:1. As far as th ratios being to far apart. I never got this.( as other offten say) The gear splits are almost exactly the same as a regular 10 speed from 2nd to 10 with low low and first being the only real difference. The 8LL is the perfect dump truck trans. A 15 speed will work also but the lowest gear is 13.31:1. Not as low as the 8LL but much lower than what you got now. A 13 speed only has a low of 12.31:1. Not the best choice for a swap if low gears are what your looking for. The 18 speed would be a real good choice for a dump truck also. It has a 14.40:1 low. Their is also a 9LL. It was designed for concrete mixers so they can crawl along with a curbing machine. It has a low low of 26.08:1. Its extremely low geared but I have seen then in dump trucks and would also work just fine.
What is your rear end ratio? I have a feeling that if your truck has a super 10 it might have been a tractor converted to a dump. It probably has very high rears and thats might be half you problem.

 

I think it might have been the engine it was behind that was the problem. 7th to 8th is actualy closer (34%) than 9th to 10th (35%) in a straight 10 speed. I do agree that you gotta love an 18 speed. However I never cared for the 15 speed. Not as low as an 8LL or the 18. Only 12 useable gears in a row and the ODs not as high so your on road RPMs are higher than an 8LL or 18 speed. How ever a 15 would be a big improvement over that super 10 hes got now!

 

80k to 85K in PA? Thought you were only good for 73,280 with a tri axle in PA? Just bustin ya! I under stand completly.

 

i have a super 10 and haul heavy all the time load in the feilds pulls out just fine but i do have a MR haney tune on my c15 so 60 or even 80 in the box is no problem i have 3:55 gears if that helps

 

I think I would have to vote for the 18 speed. Depending on what you have for power in front of the trans., I think the 18 will typically stand more torque than the average 8LL. Most times you never need all of the different ratios, but there are times when that half a gear comes in handy.
The 8LL would be my second choice, which is also a very good option. A little cheaper to purchase, and very simple to operate.
Find out for sure what you have for rears because swapping them may also be an option.
I would recommend calling a reputable drive train dealer for starters. I use Camerotas here in the north east and they have been great in helping me with all of my swaps. I tell them what I have (engine, trans., and rears) and then what I am looking to get for an end result, and they can recommend a combo that fits my needs. This route is more expensive than just finding any old tranny or set of rears for sale, but the expert advice, fast service, and warranty they provide are well worth it to me.
Hope this helps and good luck!

 

But you can shift them in a row. If it can be done with a 8LL I never figured it out. Maybe the gap was to big form 6 to 7 I dont remember it was along time ago. I just remember not liking it. I owned a 15 spd and I liked it alot. The 15spd also has 2 good reverse gears.

 

The 15 would definetly work but it sounds like his biggest problem is getting it rolling fully loaded in the soft stuff. With a 8LL or the 18 speed your still a whole ratio slower and thats what he needs. I have a feeling his rears are way to high also. Ive always found the 8ll to have two very useable reverse gears also. As far as that big jump between gears with the 8LL Im not sure where it was on the one you drove. The only wide ratio split is from low low to single low. If you compare an 8LL with a "b" ratio 10 speed single low to 8th is almost exactly the same as 2 thru 10. No big jumps their. With that said the 8LL has been around a lot of years. The early one were RTOs with the "U" shift pattern. Maby they had different ratios. This I realy dont know about but the most recent models from the 90s up have no big jumps other than low low to single low. As far as how many you can shift in a row with the 8LL theirs only 10 no matter how you do it. Buy the way the 8LL and the 15 speed are only raited up to 1650 torque. If you need to go to 1850 tq then a 10, 13, or 18 is what you need. If you need 2050tq a 13, or 18 is all thats raited that high. Theirs also a 2250tq 18 speed only. Sounds like his torque might be on the lower side though.
