Thank you for the information. I understand that number could be used for that, but I asked for an output shaft for my transmission, but they are not made anymore, and I would have to upgrade to the 3 series and I don't know if that pays. I understand it might be best to change my rear ends but I am not looking to do that if I can get it to work the way it is.

I have an 1989 Mack DMM 6906S that has a E6 225 motor. It has a T2050 transmission with this on the side 9L 1228 11KBA51406AP1 It also has an air hi/lo split transfer case and the rear ends say Hayes Dana 18918188 190F4409-P3 This truck is a silage truck with a 30 foot box and I dropped the transmission in it but it seemed so under power that I was wondering what type of transmission I could put in against my motor that I could have a little more range in between the gears so I can drive along the cutter at about 4-5 MPH and be able to get up to speed decently when loaded and be able to get up to 55-60 MPH so I can get back to the field fast to keep the cutter running. I understand that if I change transmission I may have to cut or lengthen drive shafts and I am OK with doing that. I would just like to be able to keep using the truck if possible, otherwise I will have to go a different route because I do not want to put another 5-speed in and have it just like it was before. What are your thoughts on what I should do. Thanks!!
