Bolting an LS 4l80e to a 1978 454.. Will it work and how. Ok. So I've done some research and haven't found any solid answers so I figured I'd look here. What I want to do is bolt a 4l80e to the BBC in my 78 gmc dually so I can take it on long trips. Can this be done and what parts do I need. Any help is appreciated thank you.

I've been looking into a similar type situation, only not for a truck. Here's what I've found so far. http://automatictransmission.com.au/...sp?NewsId=8611
It seems the way to go unless you want to buy the electronic device to keep it electronic. I'm not sure of the other details, but this would take a major part of it out of the equation.

For manual control, that would make it a manual valve body basically, jakes sells one and a new sponsor here sells one I think cheaper, north Texas converter.
For automatic, there is the FAST EZ TCU that I have used a couple times(550$), and there are a couple others that are priced in that range. They still require a TPS signal for auto function, but can also have electronic shifting with buttons, manual lock up(the manual controllers also have a lock up ability), and even a option for a different shift tune, for say normal and towing, or normal and performance, pretty cool features.

Idk about tuning for shift points but I've heard of using the ecu an harness off the 91-95 6.5 turbo diesel trucks there non electronic pump models an u would need an just a tps,speed an rpm signal for it to shift the trans
But probably easier to use one of the aftermarket controllers listed^^^

Depends on how it's fueled and can the computer needed to shift the transmission interact with the engine. Are you doing managed fuel injection and spark system? If yes, then I think you'll be ok.

OEM GM Transmission Controller Hi BB, the Late GM PCM SEPERATED the transmission from the PCM.
The OEM cost is $78.00 with wrecking yard cost of $25.00 ???
The CAN interface from the ECU is used for TPS, MAP, Temp, RPM reports.
What ECU will you fit ?
My ECU-882C could work fine when Pete & I finish the CAN 2.0B wording ?
