It would help just a little to know what you are putting in front of this trans. The GM PCM does a pretty good job of controlling the trans, assuming you are using the LS platform.....

I had it built by a local shop but I would say it needs a manual valvebody installed not sure what other internal mods were made but it works like a charm and I am pushing 600hp 620tq. Built, installed with converter and warranty $3000 Canadian. The linkage for the shifter I had to fab it up as the linkage that B&M (I use a Prostick) said to use was special order and took 2 weeks to canada and even then didn't line up the cable straight causing binding. I used a 5' cable run down the pass side back under trans and then froward to the trans shift linkage.
If you want to run your stock speedo you will have to change the tailhousing.
I use the tach (and the Force) for my speed so I did not change it and can always add a guage type speedo to the existing tailhousing if ever needed.
1969 496 4l80 373 gear
shorten drive shaft
custom made crossmember
In a 3rd gen the fit a 4l80 is tight but will fit without cutting the trans tunnel.
Trans cooling lines are tight to the trans tunnel. Before installing the trans Pre make short lines with connections on both ends (6" or enough to get clearance from the trans/tunnel)) with a clean bend as colse to the connection to the trans as possible without restricting flow then connect them and tighten. Then once the trans is installed run you cooling lines forward. Trying to install the cooling lines after installing the trans is tough due to limited space. Never like to have an extra connection on a fluid line but in this case it was for the best IMO
Takes a lot of fluid so keep on pouring (15+bottles) Transmisson killing heat is not a problem with that much fluid.

Here are a few pics of it installed
