    I put the information about the Tranny on the BigMackTrucks.com facebook page. You may reference the photo there under the visitors section in the right hand column. Unfortunately I was unable to attach any photos to this forum or gallery. Input on how to correct the issue is appreciated. Thank you, Luke

    totally agree i dont care what engine or horsepower you have too big of a jump between gears
  14. luke andres
    13 speed mack tranny od is .71 low is 13.91 your 2070 tranny is od .60 low is 14.16 the 2070 will run faster and have a slight lower low gear my 2080 had a low of 20.08 and od of .60 with 5.73 gears I could start out loaded on a 60 degree incline and not burn the clutch not a good tranny for the road thou in my opinion

    ill be at the shop tomorrow where my book is ill see what i can do i have never posted a pic before but have been wanting to so this might be a good learning experience
  16. luke andres
    keep in mind too that a 13 speed mack will not have as low of a low gear as the 2070 transmission in my mind a 13 speed is more of a road tractor transmission not sure how much you will be using it in the woods pulling out loads of logs i have a mack book that shows the transmission ratios for all kinds of mack transmissions and yes more than likely you will have to shorten driveshaft and redo your pto setup

    i talked to a guy in pennsilvania and he too had a early 90s dm tri axle dump that he switch out a mack 2070 and put in a 13 speed mack he also changed from 573 gears down to 442 he said his guys love driving it now said its like a new truck i went with the eaton 8ll because a its cheaper and b i had one in a parts truck and c it has a lower gear ratio than the 13 speeds mack or eaton hope this helps

    oh yeah my mack is a 91 dm 690s with a 300 em7
  19. luke andres
    i was in the same situation as you i had a t2080 mack tranny 3 lows and 5 highs i had 573 rear gears i went to an eaton 8ll and had to switch my rears to 442 to maintain top speed i like the difference not such a big jump between gear changes i had to shorten driveshaft a couple inches i say go for it its only money

    just letting all know it was a bad day today i had 20 ton of rock on my 91 dm tri axle dump when the rear gears started making a lot of noise since i was only quarter mile from where i was going i limped it there on the shoulder of the road so tomorrow i guess ill get started taking the rear pumpkin out to see the damage not fun
