One bad dog Posted November 1, 2012 Share Posted November 1, 2012 Can anyone tell me the shift pattern on t2090 thanks Quote Link to comment Share on other sites More sharing options...
David Posted November 1, 2012 Share Posted November 1, 2012 Standard five speed with reverse left and up. Use either 5L or 1H. Preselect the range before moving the stick. Quote Link to comment Share on other sites More sharing options...

Superdog Posted November 1, 2012 Share Posted November 1, 2012 you'll like it a whole lot better if you skip 5th lo and come back into lo on the high side,takes a little getting used to,but once you get on to it,you'll see what I mean.Lo.1st,2nd,3rd,split to high,lo 1st 2nd 3rd,4th 1 Quote Link to comment Share on other sites More sharing options...
leversole Posted November 1, 2012 Share Posted November 1, 2012 Do you mean using the "hidden" gear that is Lo position in high range instead of 4th on the Lo side? Quote Link to comment Share on other sites More sharing options...
David Posted November 2, 2012 Share Posted November 2, 2012 Do you mean using the "hidden" gear that is Lo position in high range instead of 4th on the Lo side?Yes thats what he means. My nine speeds whine in 4L. Quote Link to comment Share on other sites More sharing options...
rsb502 Posted November 2, 2012 Share Posted November 2, 2012 there are two different Mack 9 spds, one shifts like an eaton lo-1-2-3-4-range split-5-6-7-8 and the other is lo-1-2-3-range split-4-5-6-7-8 the latter is what I had in my 93 CH it gets you into high range quicker so in town or on low speed roads you can stay in one range the 4 hole in the low range is not to be used you go back to lo in high range like a 10 spd.

rsb502 Posted November 2, 2012 Share Posted November 2, 2012 My point being make sure you have the right one before you get crazy, the number on the side of the trans will tell you which one you have then someone can tell you for sure, if you use 4 low range and it runs almost the same speed as 3 low its the pattern above, if you drop 4-500 rpm its supposed to be used its the old style t2090.

phildirt Posted November 9, 2012 Share Posted November 9, 2012 SuperDogI ran the RW613 today and tried the shift the way you described above-- It does take a little getting used to but it does seem to be a better transition between low and high.Thanks- love it when I learn something new.

phildirt Posted November 9, 2012 Share Posted November 9, 2012 I was thanking Mike- I saw his collection about 12 years ago (I delivered the front half of an R700 for a friend to his yard). It was very impressive even then and I guess it just keeps growing. Quote Link to comment Share on other sites More sharing options...
