i have a 2000 blazer and my reverse does not work most of the time unless i am parked on a hill... sometimes i will get lucky and pump the gas and it will work but most of the time it does not. do i need to get a new tranny or get this one rebuilt or could it be something else? any info will help, thank you so much!

 

Try adjusting the shift cable
