TH350 converter in a TH350C tranny

[Magnus Klemming]

Hi
Does anyone know if its possible to use a TH350 regular converter in a TH350C transmission without problems?
Can I change without any modifications?
I am not going to use the lockup

Nope. Input shafts are different for sure, as is the pump. I don’t know if the splines are the same, but I’d be willing to bet you will trash the transmission and converter pretty quickly.
