I would very much like to fit a GM 8L90E behind my Mopar 440. The issue is that there is no stand alone TCU.
I am just starting my research into the feasibility of converting the 440 to EFI at the same time and using a GM ECU to control the engine. This could fool the transmissions into working behind the 440 since it will be using the GM ECU.
The LT4 & 8L90E crate motor combo would seem to make a good starting point. If I purchased an 809-19355174 LT4 controller package which includes an E-92 ECU .... that should work with 809-19371501 the 8L90E transmission package that comes with a compatible TCU.
This is only the seed of an idea at the moment and I am certain that most will say it can?t be done ... But can anyone tell me why it can?t be done? Perhaps somebody has all ready done this? Any thoughts?
