My neighbor has an '06 Silverado 2500HD, 4x4, Dirtymax, allison auto trans, 138K miles. I borrow/rent this truck when I need to tow/haul heavy stuff. The problem the trans is exhibiting is "morning sickness": won't shift out of 2nd or 3rd gear on cold mornings. The MIL illuminates when this happens. If it warms up the tranny will eventually start to shift as normal. Fluid quantity & quality is good.
The codes are:
P0700
P0846
P0847
P0841
I thought the allison was indestructible. Are these common codes/symptoms? Any common/easy fixes?
