Default 1jz automatic transmission rebuild?

I need the automatic transmission behind my 1jz rebuilt.. I called boost logic and they said they didn't do it. I need the transmission to be built "better" than stock because it has a single conversion and a few other upgrades. Does anyone know of a company that builds the 1jz automatics? And I don't want to go 5 or 6 speed I want to keep it automatic.. Thanks guys...

Sorry to bring up a dead post but I would like to know the answer to this as well. I have a friend that owns a transmission shop that said he could do it if I found out what all parts had to go into it.

the 1jz auto is a A340LE same as in the Aristo TT and Supra TT auto..the *E* stands for electronic controlled


get under the car and check the blue plate on the left side of the tranny....It says A340LE


Whoever told you the 1jz A340LE cant be built,has no clue what he/she is talking about

this S14 has a 1JZ auto with just valve body work.....look at his 1/4 time
