chris88 Posted July 25, 2006 Share Posted July 25, 2006 Every R model I see or hear of has a 6 speed twin stick in it. Did mack not like gears in the 80's? Did they put 10 15 20 speeds in these trucks or anything air split? Chris Quote Link to comment Share on other sites More sharing options...
Terry T Posted July 25, 2006 Share Posted July 25, 2006 Chris, We had one R S/A with the 2 stick 6 speed, the remainder of the S/A's were 5 speeds and our tandem R's had the Mack 10 speed (Superdog could tell you the model #) that you split each of the 5 forward gears (like a super 10), and could select reverse giving you 5 reverse gears. I have seen many R models with Fuller 10 speeds as well.T. Quote Link to comment Share on other sites More sharing options...
rick harper Posted July 26, 2006 Share Posted July 26, 2006 the transmission is depended on what engine concept you had, whether a maxidyne or econodyne. if the latter was selected than you had a mulitple of transmissions(multi-speeds) available. the maxidyne concept utilized the high torque rise enabling the use and simplicity of a 5 or 6 speed. the transmission model you were talking about was the trtxl-1070 ( or trdl-1070.the smiling face should have been a B Quote Link to comment Share on other sites More sharing options...

rick harper Posted July 26, 2006 Share Posted July 26, 2006 you are correct. but, in his sentence he noted that you split each hole and that is the old trtxl1070 or 1070b.in a six speed you do not split. Quote Link to comment Share on other sites More sharing options...
