5.3 lc9 gen4 transmission options?
 

Can I put a 700R4 behind this engine? Other wise I have to run the same year transmission as the engine, is my understanding? Any information greatly appreciated.

I have the engine, harness, accessories. Im missing the pedal and the other part that goes with the pedal (I forgot what its called) Im also missing the MAF, the engine is out of a 2007 suburban, can you help me out with part numbers to this stuff.

There is no conventional way to hook up the TV cable on a "Drive By Wire" engine.

I have heard talk of using the throttle pedal to run the TV cable, However even if you got geometry worked out.....The pedal would be stiff.

A '07 Suburban had either a 4L60E or a 6L80E.

Look over your harness, You will have 2 large connectors for the E38 ECM.

If you have a 3rd large connector (See Pic), That is for a T42 TCM....Meaning the engine originally had a 4L60E. Hopefully you have the TCM as well.

If no TCM Connector can be found, It had a 6L80E...The TCM is part of the Valve Body on 6 speed autos.

74-10146 airflow sensor.
If you choose to use a 700r4 you will have to use a 05 escalade flex plate.
There is no way to hook up the kickdown cable for the 700 so all downshifts will have to be done manually. That engine came with a 6l80e, too bad you don't have that.
You can go 4l60 also without having to swap flexplates.
