6L80E has no after market controller, and is tall & low so it presents packaging issues. It is not yet proving to be a good retrofit trans for the masses.

A 4L80E will let you run better rear gears and is as strong as a th400. Best of both worlds. It's a beast, it's a TH400 with 4th gear. IMO that is doing it once & right

If you do a TH400 you can probably add a gear vendors are a later date. But often later never comes.

Who is the car for?
"I may bump it to a 3.42 gear set"
"I just am not sure whether I am able to give up OD and highway cruising yet"
"He is not building a full out race car"

Now we are into gear selection, etc. Is it a turbo car? What is the total application? Is it a street car or race car? How many street miles a year on it? What is the engine RPM range?
