Title: Np205 adapter
Post by: jmduryea1 on May 24, 2022, 09:48:06 AM

Okay guys I need some help with knowing what’s compatible, I have a th400 4wd trans bolted up to a np203 and I want to swap in a np205 but the adapters are big $$ from what I hear. So I found a th400/np205 adapter for a good price and it looks more like a th350 adapter. Will this still work for a 400? Also would like to upgrade to a 4l80e in the future and I hear that same adapter is what I need. I will try to post a pic but it never cooperates for me

Pics have to be resized to 500 KB or smaller and works well when you save them as JPEG.

Are those two different adapters?

Same adapter, pics of front and back. Part number checks out for the turbo 400, I’m hoping it’ll work for the 4l80e also
