here are part #'s
15000206 - Converter dust cover
12551367 - 6.0 Flexplate
12563532 - Crank Spacer
12553332 - Flexplate bolts (6 required)
15198439 - 4L80E Dipstick tube
15183801 - 4L80E Dipstick
15013290 - 4L80E Shift cable bracket at transmission
11589040 - 4L60/65/70/80/85E Toque converter bolt (6 required)
The tranny mount can be re-used because they use the same part number (15767858)
After doing some research i thought that you need to use a Crank Spacer but I ended up not needing it
keep in mind i used my old 5.3 Flexplate
Let me get this straight I will be able to use my PI torque converter from my 65e on my 80e just by using the 5.3 flex plate?

Is it a segment copying problem (EFI Live?)

Or is it running fine but the shifts arent what you want them to be? You can PM me if you want. I learned alot this last week about tranny tuning, lol

Well crap. I cant see the tune then. If you know anybody around with EFI you can have them download your tune in .tun format and send it my way.

Just wanted to clarify that. So you basically are using the 80 file, and copying over your motor and DTC's and what not.



Got it i'll try it tommorrow
Thanks alot
