Bill... unlike OBD2 codes, transmission codes are "proprietary"... They
can't normally be accessed with low end code readers and scan tools and it
will be the manufacturer that decides on what a particular code definition
is. IIRC, your Ex is fitted with the trans that has no dipstick.. fluid
level is where the tech would have (or should have) gone after retrieving
codes. While this might not offer any clues, it still needs to be done to
rule out some basic issues. Unfortunately, the only real way to check
fluid
condition is to remove the pan.
Gear ratio error codes are most often the result of intenal transmission
concerns... this next bit is more opinion than diagnosis... The OD band is
applied in second gear as well as fifth gear. Your had OD cancel applied
while you were towing so there would be no indication of any 5th gear
concerns. Your light came on only while you were towing... this indicates
to
me that there is the possibilty that the OD band was slipping (only one of
a
few possibilities) under higher loads. Knowing that other techs have found
concerns with the servoes leaking past the plunger, I'd probably spend the
time to check the servo bores in the trans case....
What can make diagnosis extremely difficult is being unable to recreate
the
concern using "normal" conditions....
