Hey Scotty, i have a 2008 toyota corolla stuck at 299,999 miles. IS there any way to force it to go past that mileage? Would be a shame to have to replace it and start at 0 miles again

not really, but you could try going 60and have someone whack the dash

2005-2008 corollas had an odometer flaw that it wouldn’t pass more than 299999. Look at YouTube vids. A family member had one, he just used trip A and added the miles that it said on top of 299999 to get the ACTUAL mileage
