We have 11000 miles on and lots of pulling and also have it chipped. When should we service the transmission.

TOTHEMAX! 04-07-2007, 09:49 PM if you havnt done it since new, i would change it now. since you are running a chip and towing you should think about switching over to a synthetic OldSoldier 04-08-2007, 03:40 PM Manual says 15k when towing...fluid and the spin on filter. ZL-1 04-09-2007, 09:24 PM Manual says 15k when towing...fluid and the spin on filter. I would change the spin-on filter every 5k if you tow a lot also... OldSoldier 04-11-2007, 05:56 PM I would change the spin-on filter every 5k if you tow a lot also... Yep, the manual says to change the spin on at 5k, then fluid and spin on at 25k...if you tow. duramax/a 04-14-2007, 05:34 PM Book says 5k for the spin on. 50k fluid change for general service and 12k for severe. With all transynd it is 150k general and 75k severe. Spin on gets changed when you change the fluid. I changed mine at 30k and refilled (7 quarts) of transynd. | ||
