Th-400/350 uses the same torque converter.

Re: converter
Yes and no.
Although they are interchangeable, an OEM TH400's mounting tabs for the flexplate are in a slightly different location. A dual pattern flexplate or a flexplate with slotted mounting holes will allow a TH400 or TH350 torque converter to bolt up.
If the torque converter is aftermarket and wasn't ordered as a TH400 specific converter then it should bolt up with no problems.
