Default Why wont a 2001 Transmission ECU work with a 2000?

Got a 2001 trans ECU that ends with DL, tried installing into my 2000 s4, but the stock ECU ended with BS.

Shouldn't it work either way?

Default There are three different Tips.

Maybe you just have to recode the TCU for the one you have.

Default How do I go about recoding mine?

For some reason it totally failed, no signal at all. Installed the 2001 TCU and a signal was detected, but obviously didn't work.

I already ordered a new TCU off a 2000, but if I could recode mine and save $$ thats always great!
