I have a buddy with a TH350C in a van and I have a TH350 in my drag racer. I'd like to only get one rebuild manual if these trannies are almost the same.
Does anyone know how they differ? I know the TH350C has lockup, but what else is different? Just the valve bodies or are the rotating assemblies different too? Thanks.

I just got done completely rebuilding the 350C.
The main thing I could tell is that there is an auxillary valve body with the lockup solenoid stuck to it on the TH350C. Also I saw in the Chilton manual that there is an additional check ball if you have lockup. I didn't rebuild the pump, but that probably had some lockup specific instructions as well.
Clutch clearances, bolt torques, and endplays seemed to be the same for both models.
