Auto tranny control ecu

[fireblade]

Do the auto transmissions have their own computer or is there one for tranny and engine.I know the one in passenger foot well does engine, there is another box that looks like a ecu in drivers side foot well or is it?

yep thats right the one on the passenger side wall..is the main ecu and the one on the drivers side is the auto box.

Yep it sure does have a separate ECU for the auto trans, it will also have a shift lock-out control box connected to the auto shifter too! I have removed mine as my car is manual now.

This next bit of info is a bit off topic but interesting none the less:

The R32 GTR uses one kind of wiring harness but in the GTS4 and GTS-t models there is four different wiring harnesses eg:

- A/T with auto spoiler

- M/T with auto spoiler

- A/T without auto spoiler

- M/T without auto spoiler

This makes it fun to do a conversion from auto to manual unless you have a manual wiring harness! although it is possible to use the A/T harness if you find the plug on the side of the fuse/relay box in the engine bay, this plug has only two thick wires going into it you need to connect these two wires together to be able to start the engine, (the A/T equiped vehicles have a ignition cut-out system) also the reverse lights need wiring too.

But I changed the entire wiring from auto to manual because I changed the engine too.
