hello i have 99 yukon 5.7 with 4l60 trans with six hole bell housing picked up a 2000 4l60 with 7 hole bell housing extra hole top center , both bell housings shaped the same 7th hole housing a little deeper with a little deeper converter, six hole housing has 4 small screw hole for dust shield pump shaft seems to the same- can these swap as is or do i need to swap bell housings and converters

ok so you are saying put my old bell housing and converter on newer trans

 

[SunlitComet]

no take the whole thing over.

 

[spider9]

so my question still will the 7th hole at top center make a difference// i took off a six hole bell housing with no hole top center// newer trans has hole

 

[SunlitComet]

just leave the hole unused.
