How do I get my truck to hold Overdrive?

[DMAXTODD]

Ever since I drove that 02'last week I have been obsessed with making this thing hold O/D. I know alot of you guys have gotten upgrades and might have some advice on this. The only one I have done is the C/C upgrade which only helped when in cruise. If any of you are crusing at 45 to 50 and press lightly on the trottle does yours downshift instantly? I think this on was built with hyperactive downshift tuning or something.

DMAXTODD,

I would make sure that you have all of the ECM and TCM updates performed. The TCM is updated separately from the ECM. The updates seem to have solved this complaint for most.

I'm transferring this topic to the 2500HD/3500 HD Trucks & Drivetrain forum.
