Re: Th400 - np205 adapter

What version ? Fig 8 or round 6 205 .

And yes its the trans side that needs the attention.

Round 6 style they make a adapter/ spacer for ZERO mods bult up .

Fig 8 needs little more work .

What 4l80-e trans output shaft length are you running ? Stock 4x4 or 2wd slip fixed or full spline 2wd ?
