4L80E guys come on in
What am I missing? What will I have to modify?
I've heard my M6 crossmember can be modified and my tranny mount can be used on the 80E. What will I have to do to the crossmember?
What did you guys do about the torque arm? It won't mount to the tranny so do I have to get another torque arm? I have the stock torque arm and 10 bolt. Oh, I have true duals dumped at the axle too.
I've read I have to cut the ears on the bellhousing. If so anyone have pictures?
What I have:
PCM sent to get flashed (Frost)
A4 pedals
A4 console
Speartech harness
Shifter
Trans cooler and lines
Transmission
Transgo HD2 shift kit
Converter (not yet) waiting to figure out what stall and manufacturer
Flywheel (not yet) Ordering after the torque converter
Is there an alternative to the Lokar dipstick? $100 for a dipstick seems excessive.
Any idea how long my driveshaft needs to be? I'm just going to have mine modified.
Any pictures or help would be appreciated.

A pic of the ears that need cut off. You will see where you need to cut. You will have to clearance your trans tunnel for the transmission plug.
You can use the speartech harness or extend the wires of a stock plug and pin them into your PCM. I chose the later as it was cheaper by far.
Madman sells a 4L80e dipstick that is a lot better than the Lokar one. I have the madman dipstick and it fits perfect.
I am using my stock driveshaft with a conversion u-joint. No need to modify it in anyway.
Only other thing you may need, depending on how you run your trans cooler lines, is the correct fittings that go into the trans. Here is a good thread in regards to early year (Pre-97) 4L80e fittings.

There's a thread for a 97+ case and the fittings needed.
If you have any other questions, let me know. If it is in regards to wiring it in, I am not the one to ask though, lol. My buddy took care of all of that.
I've rewired this entire car including some of the computer pins. I really hate wiring!! I was going to get the TCI controller but $500 wasn't in the budget for it.
I'll have to look at the BMR crossmember. How does your torque arm mount up?

To chime in on some other things......those are Summit PN#'s
-Slip yoke- Strange STR-U1650 (same as TH400 one)
-Torque arm- Call Eric at Midwest Chassis. He sells a chassis mounted torque arm setup and 4L80e conversion crossmember. Ultimately, its a much better setup than a full length torque arm. The M6 crossmember cannot be used and would need to be heavily modified.
-Use the stock driveshaft, and get the conversion ujoint. I think its the Moog 1344 to 1350 ujoint, but I could be wrong. MOG-447. Call Jake's and they'll hook you up with that and the slip yoke.
-I have the TCI 399-753 flexplate
-Call Dave @ Yank or Chris @ CircleD for a converter. Let them know what flexplate you are running.
Good luck. Keep us posted.

I really like the short torque arm and mount too. I know it'll be better than the stock ****.
With regards to the converter, you don't need a $900 converter to get started. Companies can make you a cheaper converter, in the $500 range. You just need to know that it will not likely perform the same as the $900 one.
Check the classifieds daily for a used flexplate and slip yoke. You never know.
