weird transmission behavior
I have a 250, lwb, med roof with the 3.5 eb and ls 3.73 (tow group). I just clicked past 5000mi, I deliver for a living...so high miles. Also I tow quite frequently...anywhere from 1000lbs up to 5500lb
Overall I am very pleased. The transit has gobs of power and torque. There has not been a situation where I have a want for more power.
So here's my question....does the transit have any type of hill or descent control? About 90% of the time the transmission goes into 6th and stays...towing or not.
However, sometimes when descending a moderate hill, the transmission will downshift rather abruptly to 5th or even 4th. It does not matter if I am coasting or slightly braking....does not matter if I have speed control on or not.
As I mentioned, only every once in awhile...in hilly driving. Seems to happen slightly more if I am towing. It is the only issue...transmission is smooth otherwise. Nothing else weird.
Just seems like it is downshifting when I don't want it too.
Can the dealer reflash transmission program?
