TH400
1966 model year
Output shaft for D20 - no adapter(broke)
AMC belhousing, w/ torque converter and flexplate for 360
EDIT: Pulled the trans. PO must have had a TC bolt loosen. There are a few peek holes in the bell. Need TH400 parts?
Now for sale: Buick TH400 to AMC adapter, flexplate & hardware. Make offer.
Also have D20 t-case complete w/ input gear for TH400 (TH400 output shaft) TH400 to D20 adapter broke.
Make an offer, get this stuff out of my garage.
I don't want to haul it to the junk yard!
The factory TH400 to D20 adapter is very weak. I would recommend one from Bulltear here: Bulltear Adapter
