I’am the proud owner of a k20 with an automatic transmission. I’d like to convert it to a manual if possible. The question here is, is this possible and if so what transmission would I need I’m assuming an m22 rock crusher. Thank you for all the help

 

What year is your Chevy Pickup? Might well be a Borg -Warner transmission that you'll need to change to a stick.

 

it’s a 1986 suburban with a 454 and 4wheel drive

 

Your 86 Suburban has a Warner transmission
