Just to clear up any confusion regarding terminology - there are two castings that bolt between the engine block and the transmission case. The "adapter" that Dougal shows bolts to the engine block and provides the mount for the starter. It is the same part number for both the automatic and manual transmission. Between the "adapter" and the transmission case is the "bell housing" Normally, the bell housing would be considered part of the transmission, but with Isuzu, they are a seperate piece that bolts to both the tranny and "adapter". The bell housings are different for the manual and automatic transmissions.
Having multiple pieces between the engine block and the transmission case provides us multiple options for adapting the 4BD1/2 to TLC: 1) Replace the "adapter" as RHINO suggests. 2) Sandwich an adapter ring between the "adapter" and a TLC bell housing. 3) Use an Isuzu "adapter" and bell housing and sandwich an adapter plate between the Isuzu bell housing and a TLC transmission case. 4) Use the Isuzu "adapter", bell housing and tranny (manual or automatic) and fab an adapter between the output of the tranny and the t-case, similar to what Dougal did.
Crushers:
If your going to quote this thread, at least do it accurately. There have been several other engines besides the Isuzu 4BD1T and 4BD2T discussed here including the Isuzu 4HE1-TC and the Cummins 4BT. Your comment regarding exhaust being on the opposite side to that of the 2F and 3FE applies to the 4HE1-TC and not the 4BD1/2. The need for a lift applies to the 4BT and hasn't been determined for a 4BD1/2.
