Update on loss of Turbo Boost and check Transmission light

[Gregory OConnor]

Kerry, I disagree with you guys. Early smog computers had their
problems but the entire thing is getting more user friendly. When a
mechanic looks at an issue and sighs or says "fangled thing", run.
Find one without fear of computers because he/she is not blaming the
computers existence for their ignorance of the product.

Early computers were effected by battery charging and jump-starts but
that was corrected when problems arose. It seems that things that
could go wrong did go wrong with 1991 8V/Allison setup in the
trucking business by 1995 when the fleets had 450,000 miles on them.
The uniqueness of the RV is low-miles little-use, constant battery
charge/discharge, two battery banks and age of equipment.

When a non computer rigs Airfilter gets clogged it burns too rich it
billows black smoke. When a computerized rig gets a a/f clog the
computer shuts down a function that will not allow it to blow smoke.
that function usuly reduces rpms and often sets off confusing signals
to the trans shifting computer. Something tells the computer that
there is restricted flow. If that signal is sent and there in no
restriction in flow then it is a bad sensor and or wire link to the
computer or from the power source. Understanding the computer is
key.

Computerized engines have less major part failures because root
causes of major failures are detected when they are subtle issues.
Many folk view frequency of minor issues with computerized engines
and transmissions as a bad annoying thing. They overlook the fact
that these 'Check trans/engine lite occurances' become major problems
that go undetected on the non computerized engines/trans.

To answer your question, I thought about getting a code reader but
dont feel confident enough to understand what the "fangled thing" is
saying.

I wish folk like JohnFinn and TomWarner would jump on the DD/Allison
computer bus so I could learn more about my rig.
