Default 2009 Silverado Hybrid Transmission

Does anyone have any leads on where I can find a transmission (2ML70)? Used, new or otherwise?

TIA

It's got a crazy rattle on cold start up, whining between shifts and on really cold mornings it has to warm up or it won't move.

the humm is from the electric motor spinning (or the rear speakers due to a noise from the HIGH POWERED 3 phase motors )
you probably have some "noise" leakage into the 12volt system making the speakers audioable as they are "always on" (as they do BCM sounds)
check the ground wires for damage,dirt or corrosion..

normal for a CVT (same for reverse as it's CVT ) just back it in at night and put it in M to go forward
what about M4 mode?

those sound like pretty normal things


you know the target market for these hybrids were California not where you live

as you can see nasty stuff builds up on the wires and cause trouble for you there is also a hidden ground wire behind the inverter besure to disconnect the power lines before cleaning them...
Don't touch the orange cables if those are dirty they need to be done by a Pro. as they contain high voltage
