4L80E in a Camaro

[Mike@Vengeance]

Do I need to download a special 4L80E content or is it basically the same as the stock trans.

I know HP they do something to them but not sure with my EFI. Can I just plug and play or is there major changes that need to be made.

Thanks for any and all Help guys.

You have to copy the 4L80E transmisson segment from a file that has the same OS id as your file...
if you do find a matching file, start at step 3 below.

If you can't can't find such a file, then find a file containing OS 12212156 and a 4L80E transmission segment... it would be a truck file.
you also need to find a 2002 Camaro 12212156 4L60E file, you will be upgrading your OS to this;
if you're going to do this, your PCM must be 1999 or later, upto 2003 I think (i.e. a 0411 PCM with 512KB flash);
in this case start at step 1 below.

See www.holdencrazy.com (http://www.holdencrazy.com) for these.


Then, follow these steps:

1. copy all your old tables to the 2002 Camaro 12212156 4L60E file:
open two instances of the tunetool (one on the 1221216 4L60E file, the other on your old file,
and copy each table (table-by-table) using copy-with-labels/paste-with-labels);
save the new file.

2. close the old file tunetool instance.

3. in the new file tunetool instance, open the truck 12212156 4L80E file as the alternate file;
copy the transmission segment from the alternate to the calibration (Edit->Copy Segment->Transmission Segment);
save the new file.

4. do a full flash of the new file to your PCM.

5. make sure your motor and transmission operate correctly.
