Hi,
please could someone assist with finding out the following for Chevrolet LS3 and 6L90 transmission?

Pin allocations for interface connector to vehicle
Mating connector part number
Any circuit diagrams
How the engine communicates with the transmission (databus?)
Shift selector interface
Start lockout and start inhibit relay wiring

Is there a good source book I could buy?

Hope someone can help...

Thank you Doctor Volt!
Is it J1939 CAN as per Allison transmissions or a protocol proprietary to GM?

I'd already worked out that there were seperate engine ECU and transmission ECU...I have a contact in the United States whom I am dealing with now but we are working to an exceedingly tight timescale hence the need for multiple enquiries in different places.

regards

Yes I already knew by your opening post that you knew about the system layout but needed as much information as possible regarding communications and all other circuits

My post was to help educate a guesser

Sorry I have no information for you but will keep looking

I will get on it now and post back here if I find anything that may be of help
Hi,

Good morning DoctorVolt!

Thank you for your assistance in finding data regarding this powertrain, unfortunately client confidentiality means I must be very careful what I post about the intended application.

I've found a supplier in the United States who can supply missing components (such as the harness, accelerator pedal, shift selector etc. PM me if you would like contact details.

The suggestion with google search was appreciated too...

regards and thanks again!
Matt
