Alright so I'm changing my auto out for a manual and need to know what all needs to be changed in the tune. Or if someone can change it for me I can post it up. Thanks in advance

any one? theres no chevy suburban with a manual in it so i cant just copy a tune. i need to get this figured out before i drop the trans in i can handle every thing except the tune change for a manual. ive been searching and had no luck yet. once i get this part figured out im ready to put every thing in and get my drive shaft measured up

It has been discussed many times. Use your current tune and just shut off the trans related codes. Your idle may require slight adjustment but that's it.

All I did in mine was shut transmission abuse mode off (mine is a 5.3/sm465) and as stated ^ shut off all dtc's that involved the transmission
