Vladislav Posted May 3, 2015 Share Posted May 3, 2015 Your question is not too easy.You mentioned many different transmissions and many of them were from different series of the different ages.Sure not all of them were 10 speeds.I can tell you forget about TRD-72 series. They are old single countershaft trannies, used mostly on B models etc. in sixties.T200 series is Mack newest serie and T2100 is 10 speed indeed.1070 series conteins 10 spd either but I'm not familiar with it.Dig out the Wiki section of the forum well and look over the threads posted along the theme.Look over ebay, there are usually many offers on service manuals and trannies itself.You may try to identify what you have in your truck just relating your stuff to pictures posted there.Vlad Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/39869-transmission-identificationhistory/#findComment-288659 Share on other sites More sharing options...

Solution kscarbel2 Posted May 14, 2015 Solution Share Posted May 14, 2015 How do I identify my transmission model?On the left side of your Mack transmission, toward the rear of the main box case, is the stamped identification information.1. Mack transmission model number2. Serial number3. 11KBA assembly number4. P number, which designates the variation of the main assembly.The 11KBA number is used together with the P variation. As in this example, 11KBA51478P1. This is the number Mack dealers use for looking up your desired replacement parts..
