dek1581 Posted July 24, 2015 Share Posted July 24, 2015 is there a chart of some sort that breaks down the different tranny models showing how many speeds, ratios etc etc? Quote Link to comment https://www.bigmacktrucks.com/topic/41064-tranny-decoding/ Share on other sites More sharing options...
kt_Engineer Posted August 25, 2015 Share Posted August 25, 2015 Hopefully this will help. Please be aware this is a old datasheet. The T306G, TM308, TM309, TM308M & TM309M are no longer available. The T310 is good upto 1860 lb-ft and there is a new T310ME21 that is good upto 2100 lb-ft.I can provide all ratios if you are interested in a specific transmission. I can post all ratios for all available transmissions in a tabular format if required.MackMaxiTorqueEST300Trans1.pdf Quote Link to comment https://www.bigmacktrucks.com/topic/41064-tranny-decoding/#findComment-301408 Share on other sites More sharing options...
TeamsterGrrrl Posted August 25, 2015 Share Posted August 25, 2015 So the wide ratio (60% split) Maxitorques are no longer available? Quote Link to comment https://www.bigmacktrucks.com/topic/41064-tranny-decoding/#findComment-301433 Share on other sites More sharing options...
kt_Engineer Posted August 25, 2015 Share Posted August 25, 2015 Yes. The TM transmissions are no longer available. Quote Link to comment https://www.bigmacktrucks.com/topic/41064-tranny-decoding/#findComment-301438 Share on other sites More sharing options...
TeamsterGrrrl Posted August 25, 2015 Share Posted August 25, 2015 Kinda sad... After a half century of enjoying the reducing shifting of Maxidyne engines and wide ratio Maxitorque transmissions, the only choices left are close ratio transmissions that require twice as much shifting or the questionable durability of Volvo's automated single countershaft transmission.

MHfred Posted August 25, 2015 Share Posted August 25, 2015 I guess you wanted Mack tranny info but in case you or some else is interested, here is a very good Fuller chart I found on their website, I think. Click on the number of gears on the bottom and a list of transmissions with those speeds and their weight and length will show.Fuller ratios & weights.xls Quote Link to comment https://www.bigmacktrucks.com/topic/41064-tranny-decoding/#findComment-301464 Share on other sites More sharing options...
