Np205 adapter
« on: May 24, 2022, 09:48:06 AM »
Okay guys I need some help with knowing whatís 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.
