The external trans. filter has been changed every oil change. Should it be changed? KEVINL 03-20-2007, 10:33 PM I would change it Asap I think the recommended interval is 50k most of us change it before then. tuney443 03-21-2007, 08:44 AM Ok, here is another question.The tranny in my truck has 85,000 miles and the fluid has never been changed. The external trans. filter has been changed every oil change. Should it be changed? Definitely.For severe service,its 25K,normal 50K duramax/a 03-27-2007, 10:33 PM The transmision is rated at 26000 pounds BH in AZ 04-05-2007, 03:03 AM Here is another recent thread on the subject: http://dieselplace.com/forum/showthread.php?t=140473&highlight=weight franklinman1999 04-07-2007, 08:11 AM I would take that rating as a reflection on the other components in the vehicle. Tires, wheels, etc as being the limiting factor in this rating. This same basic tranny is used in school buses, concrete trucks, and even tanks. Not sure of the weight of a concrete truck when loaded, but the ones I see around here have 66,000 lb plates on them. The tests I have seen indicate that this tranny is designed to last 500,000 miles or more while moving a load of 70,000 lbs or more. Don't worry about it braking, it is an Allison. huthuthut 04-07-2007, 11:17 AM Don't worry about it braking, it is an Allison. :rolleyes: As I sit with an 05 Dmax in the driveway with a blown tranny. Take care of your Allison and protect it if power modding! tuney443 04-08-2007, 11:28 AM I would take that rating as a reflection on the other components in the vehicle.

It's all relative to how you drive,your PM schedule,etc. The best out there yes,but not bulletproof. | ||
