Rob Posted April 21, 2011 Share Posted April 21, 2011 Guys,What is the proper nomenclature for the six speed TWO STICK-not air shift- that was used with 237 Maxidynes?TRDL-107 if direct, TRDL1070 if overdrive, and TRDL-1071 if the deep reduction low gear; 23:1 reduction. The low reduction trans was only available in direct as is my understanding. I have one in my R795 and it's a nice gearset.Rob Herb is correct as the TRDL-107 is an air shifted 10 speed. I have this trans in my RL797. The trans in the R795 is a TRXL1071.Sorry for the confusion.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

HK Trucking Posted April 21, 2011 Share Posted April 21, 2011 TRXL107, or TRXL1071, depending on whether it's the "lo", or "lo lo" version.At the beginning of the Maxidyne era, there were also the TRDXL 107 & the TRDXL 1070, but those are much less popular.

Red Horse Posted April 21, 2011 Author Share Posted April 21, 2011 Guys- Rob says .."air shifted." I'm talking about the one with two sticks- not the one with the air valve on the stick.

Rob Posted April 21, 2011 Share Posted April 21, 2011 Guys- Rob says .."air shifted." I'm talking about the one with two sticks- not the one with the air valve on the stick.Yes, we understand your question. Herb is correct in the answers provided. The air shifted six speed transmissions had an "A" designation after the number.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Red Horse Posted April 21, 2011 Author Share Posted April 21, 2011 10-4 guys- thx- I have Duplex behind a Maxidyne in my 56, and everyone keeps telling me the back half won't take the torque of a 237 so I'm planing ahead.

A "Maxitorque" will eventually fail with abusive treatment although they are much heavier built for the "Maxidyne" high torque rise series of engine.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
