diggerpro Posted August 11, 2014 Share Posted August 11, 2014 I have a beautiful B-61 that is sitting in my shed because of a failure of the aux section of it's Unishift Transmission. I'm looking for some help finding a replacement or a parts doner one or as a last resort possibly a duplex trans to put in it until I find the correct replacement one or parts. My truck has only just over 200,000 original miles and as far as I know NO body filler in it anywhere---- So it's way too nice to leave sit. Any help would be appreciated in the form of parts trans or referals . I've posted this here before and had lots of great guys try to help but just haven't connected with the right stuff yet- My trans is a TRDL 725 . If anyone has replaced a Unishift with a Duplex Id like to know what Im in for to do the change over with the air assist clutch and bolt ups- Feel free to call me anytime at 570-419-1099 Thanks to all that have tried to help in the past- Quote Link to comment https://www.bigmacktrucks.com/topic/36647-need-help-on-a-mack-unishift-transmission/ Share on other sites More sharing options...

Maddog13407 Posted September 1, 2014 Share Posted September 1, 2014 the newer number for a duplex is a TRD722. im sure there is a reason. probably a bearing or something changed. think Mack changed the number around 64-65 Quote Link to comment https://www.bigmacktrucks.com/topic/36647-need-help-on-a-mack-unishift-transmission/#findComment-258127 Share on other sites More sharing options...
