Yes and no.
Also they now have a 4L70E
The E is for electronic control.
They will still bolt up to a chev 4.3 V6 or V8 engine but.
About the only thing that is the same is bolt pattern transmission to engine.
Inside parts and inside case and converters and valve bodys have changed every few year.
And one for a V6 will have fewer clutches and different converter than a V8.
