guys i have an 09 silverado i want to add a circle d stall 3200 at the least. but i want to upgrade my tranny to be able to have it last. would a shift kit and servo and bigger tranny cooler be enough? i really just want this truck to be DD with bolt ons thanks.

 

Poor shifting and heat besides abuse kills trannys...mine died...lol. Shift kit, servos and cooler would definitely be good for a dd with bolt ons. However, chances are after awhile, maybe a year or so, you will want to add other stuff like most of us...lol, so i would buy a tru 40k cooler and servos since they're cheap to begin with and start saving up for a good tranny.... The 09s come with a 4l60 still??? Good luck bro....

 

Is it still a 4L60? Or is it a 6L80? You can get either in the 09 model. If its a 4L then the usual upgrades will work. A large efficient cooler, transgo hd-2 shift kit, metal accumulator pistons, and a corvette servo usually do the trick. The valve bodies are slightly different on the 09+ models, and I'm honestly not sure if the HD-2 kit will work. I haven't messed with them yet.

 

thanks guys i think after some research i am going with the tru cool cooler and the hd shift kit plus servo for now dont really hammer away to much at the tranny but hopefully it will last after i install a converter
