dozerman1 Posted December 21, 2015 Share Posted December 21, 2015 Anyone have any idea what it would take to change a Mack T2070 transmission to a 9 or13 speed fuller.Driver ran transmission low of oil and it can be repaired but I have never really liked it.I think giving the truck a few more years would do wonders for it.Any thoughts anyone or advice?

RedBullDog Posted December 21, 2015 Share Posted December 21, 2015 Just remember when comparing an overdrive Fuller to an overdrive Mack transmission, the fuller will have a less "overdrivey" tall gear. I hope that makes sense, my mind is shot from holiday stress. There will also be a difference in drive shaft length. Quote Link to comment Share on other sites More sharing options...
alex g Posted December 21, 2015 Share Posted December 21, 2015 I believe you need to change bell housing as well and I think pilot bearing is different between the two also I have a mack to fuller/Eaton bell housing here if you need oneSent from my SM-G386W using Tapatalk Quote Link to comment Share on other sites More sharing options...
MACKS Posted December 21, 2015 Share Posted December 21, 2015 How about a Mack 12 speed ? 2 Quote Link to comment Share on other sites More sharing options...
masterwelder Posted December 22, 2015 Share Posted December 22, 2015 Possible bell housing, trans mounts, the way the clutch cable attaches, length of trans (shorten or lengthing drive shaft) speedo hookup, final output ratio of transmission ( rear gearing change) shift lever. I've done it. It's worth the effort if you do you homework. Best way is to get the doner trans from a mack, preferably around the same year. I'm getting ready to get rid of the mack 9sp for a fuller. My mack has a .71 final drive ratio with 5.55 rears so any swap I make will also require a rear change to get any road speed with a decent rpm.

terry Posted December 22, 2015 Share Posted December 22, 2015 You will have to change rear ends too, a 2070 runs about 5.50 rears. Quote Link to comment Share on other sites More sharing options...

Vladislav Posted December 22, 2015 Share Posted December 22, 2015 T2070 has quite fast owerdrive, 0.60. Much faster than T2090, T2100 and T2130. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment Share on other sites More sharing options...
Outbehindthebarn Posted December 23, 2015 Share Posted December 23, 2015 T2070 has quite fast owerdrive, 0.60. Much faster than T2090, T2100 and T2130.I did not know that, I thought Mack overdrives were all the same. 0.60 thats a hell of an overdrive!

Keffer inc Posted January 10, 2016 Share Posted January 10, 2016 It would be hell at the parts desk too. They look up everything by the VIN. If you use something else, they won't be able to find it. Quote Link to comment Share on other sites More sharing options...
