Sounds like the clutch pack didn't get the lipseals refreshed, or/and was driving around Low-on-Fluid and schortched the FWD Pack. Clogged Fabric filter.
This is a 10-foot pole drama of errors to me, so don't want to get involved: too far away for eyes-on guidance. Aside from that:
Replace the Front Pump, Converter because something got whacked badly. Take high impact to crack-out a Converter Neck fracture. Front Pump bushing-bore took the force.
Visual inspection of bushing wear, parts wear is the big deal for the TH400, all rebuilds.
FWD drum: look for scoring inside the 2-seal ring contact area and shaft wear there.
DIR Pack: needful to perform the Mid-Seal removal, Center-support 2nd ring removal, and Reverse-Bleed tiny-hole plugging in Separator plate. <-- a modification for nice 2-3, 3-2.
Valvebody: Flip the 2-3 Puck, toss the big valvespring, puck immoble in VB (some pucks may have 3-tabs to gring down)
use only 3 checkballs: they are nearly in a straignt line in the Case.
In conclusion; Good luck, and donta want to get involved beyond the above-typed internet advice. HIS
