The kit was from PPE and costs about 10 dollars. It includes 3 washers about .030" thick, but you only use 2 the other is a spare if you drop one and cant find it. It also comes with a nut to seperate the valve.

Hi there, I recently installed a Diablo Sport Tuner in my truck. Traded a guy for my Hypertech. Love the power and milage i gained over last tuner. However when i put the pedal to the floor from a stand still it has shift problems around 80 km/h and 100km/h. Seems to hesitate a second and then shift. If i ease into the pedal a bit it doesnt have this problem. I am wondering if the update will help this or what is going wrong here????
I have a 4'' turbo back exhaust and an AFE stage 2 cold air intake. 07 LBZ, Tuner is U7186, v.9r02. I am on the 85 horse tune. would like to try the 120 but am having shift problems on the 85, tells me it isnt going to get better on the 120. When i drive normal and dont have it to the floor it shifts nice. Just when i hold it right down in a drag race. My buddy has same truck same mods same programmer not sure on software version but he has similar problems at times as well. Can you help??

Good Times!!

thats your trans telling you it does not like you and your new torque output :)

this is not an uncommon occurrence in the Alillison/Duramax world, best option is to look into a soft part/clutch upgrade, along with a fresh fluid/filter change, and the holding capacity will be increased quite a bit...
