Is my trans tune bad?

Hey there Nube here,

My 4L65E after a rebuild for a smoked 3-4 band, goes forward in 'N" & will hardly move in"R" even after 2 more rebuilds! It would do this randomly & seldom & it burns the 3-4 bands. I've bought a Level VI from RPM & want to make sure theirs nothing wrong with my tune to cause what happened before to happen again! HELP please

Find a good builder, you shouldn't be having issues like that. Your tune looks fine except minimum tcc duty cycle should be 90 your max is fine
