The TH-350 uses a square pan, with one corner cut off. The TH-400 uses an oblong-shaped pan with one side having a “hump” in the pan and one side is curved while the other two sides are straight. The TH-400 pan also has two circular indentations on the humped side of the pan. Measure the transmission.

The TH350 (Turbo-Hydramatic 350) and TH700R4 (Turbo-Hydramatic 700-R4) can be thought of as relatives of a sort: uncle and nephew, if not father and son. The venerable TH350 saw duty in some of GM’s most prestigious hot rods and is strong enough for most non big-block applications.
