Auto Transmission Noise in Manual Gear 3

TSB LA307-001
"A customer may report a concern of an unusual noise from the transmission/drive line when driving with manual gear 3 selected under light throttle applications between 1500-2000rpm. The noise may be described as a 'scraping' or 'dry bearing noise' but is not apparent in 'D' (drive) or other gears.

Cause: Under certain specific conditions, the torque converter causes an undetectable vibration which causes the transfer box drive chain to shake, resulting in the noise.
Action: On a customer concern basis only regarding the above, refer to the Service Procedure detailed in this bulletin to update the transmission control module software."

I did hear that noise, yes, but rarely use manual mode so thought I'd mention it at next service. It obviously sounds worse than it actually is - it sounds quite nasty. Yes, it is amazing what s/w can fix.

Now I can go at thim with the solution, as well as the problem.

They should pay me for saving their time!

no no, it's amazing how software and electronics can break down proven mechanics Wink In a time of chimpanzees, I was a penguin.
