LB7: Did I limp it?

[77cruiser]

I was out playing dirt track on some back road, didn't notice anything, but after I coasted down a hill I noticed a light on the panel od with a slash through it.
After I shut it off & restarted it went away & trans shifts normal.

BTW it might have shifted to OD while I was playing & the tires were spinning.

Overdrive lockout?

that just means you locked out overdrive, were you holding in your towhaul button?

Yea I pushed when I went down the hill, but it didn't downshift like it normally would.
What's with OD lockout? Still have OD in towhaul.

if your service engine light was on you may have limped it, but it sounds like your OD lockout engaged. what year is the truck? hold the tow haul button down and when it does the same thing again you'll know that it was the OD lockout.

04 & yes I think that's what I did pushed the tow/haul must have held it for a bit. I didn't realize these trucks had all these little tricks. :thumb:
