The first problem I had was when I tried to tune it using the setup wizard in the Edelbrock app it wouldn’t get past the gear indicator test meaning I was t recognizing me shifting through the gears. I knew it something to do with the pressure switches after a few tests with my ohm meter. So fluid drained back out, front drive shaft back off, crossmember removed, drop pan and I found the my trans builder forgot to plug in the switches. Ugh! What else did he forget? So back together it went.
Next problem - on the first road test I couldn’t get it to lock up the torque converter. After many calls with clueless edelbrock tech support. I was ready to scrap the edelbrock trans controller and go with a different unit. Ironically the only review on Summit mentioned this problem and a 1 star review. So I started researching trans controllers that were canbus enabled as come across compushift. The more I researched i was convinced they must be building them for edelbrock. So I called their tech support and the first question he asked me if it was a 4x4 and was the transfer case wire ran. And I told him it was. He told me to disconnect it because I do not need it and the 208transfer case won’t send the correct signal for it. Problem solved! The funny thing is is that I called edelbrock before I bought this and asked them what type of signal was the transfer case supposed to send and they couldn’t give me an answer. Long story short if you need tech support don’t call edelbrock.
The 4l80e makes this thing a dream to drive. It shifts nice and smooth cruising but when you stomp on it it will just about break the tires loose when it shifts. And 2300 rpm when going down the highway going 70 ain’t bad either!
Not many pictures from the install but this is what I got.

Nice work and thanks for sharing the info on the transmission controller. I sacrificed over drive for the reliability of a TH400 after my 700r4 blew up. Have contemplated a 4l80 ever since. I have a np208 transfer case as well.
