I have had this truck since it was bran new.it now has 110000 miles on it ans is giving me some problems.this first problem is I keep getting loss of communiction undefined codes.second the trans has po700 and p0735.also truck is hesitating and blowing white smoke at about 140 degree enging temp.not sure on undefined codes but with the trans is it pretty much a guarantee that its toast.with the smoke and hesitation I was thinking injectors or fpr but not sure at this point.balance rates are with in the +4-4range.any ideas or help would be great thanks.no loss of power, coolant, milage.

Is it the old edge juice?

Sounds like the trans is getting weak. What power level are you running? You might could try unplugging the edge and driving it for a while. See if that takes care of your no comm. codes. Also Id say your trans wont give you fits with the box off. The hesitation could be a turbo vane problem or could even be a prob. with the edge. If you cant live without the extra power then a trans overhaul is in your future.

Default Thanks

this is the old edge juice, and it is always on level 1 .turbo vane sensor and actuator have been replaced. I have tried removing the edge and it has no effect. Did the ice pic fix on all the injectors again and looks as it took care of the one problem. The trans I bought the Allison manual and was getting ready to rebuild it, but when I looked at it I seen that there was a third sensor on the trans. So as strange as it sounds I cleaned them up and put di-electric grease on them and have installed the edge and all seems to be ok.
