BTW , I recently went through a P0783 , and no OD . I tried different solenoids before finally replacing the trans(solenoids are in the trans I am using now) . After it was removed , I found out about the accumulator spring and it's issue with breaking and then no OD . Pulled the 5 screw cover and voila , 2 piece spring . I feel pretty confident I could have gotten OD with a new spring , 123 shifted great . I opted to switch because the oil had been let run really low , and some , well , a lot of debris in the pan when I opened it up . I didn't want to do the labor on the trans swap so I gave fixing it a shot , sure wish I would have tried the spring before swapping . I'd do a motor swap over the trans any day . After what I have experienced , I would certainly point the finger at a broken spring . Just thought I'd let you know
. Could be a $10 fix , plus oil
Gas hand accuracy and DTE's aren't the greatest way to gauge what's left in the tank to take you that last 50 miles . I just filled up , drove 43 miles (70kms) since , and it's telling me 380 till empty (604kms). That's about 90-100 miles off what I will get , minimum . Never reset anything either . If I ran it down to using 21.5 gallons , that would make my 5.9 do 19.7mpgs . That would be better than the 14.2 I just pulled from the previous tank , same station used .
