Customer Question

SRT8 6.1 Auto trans making buzzing sound.
Submitted: 10 months ago.
Category: Australia Car
Customer: replied 10 months ago.
Seems to be slipping when in reverse more than in drive.
Expert:  sprinkles08 replied 10 months ago.

Hello and welcome to JustAnswer!

A buzzing sound along with slippage usually indicates a restricted filter. If the filter becomes restricted it will cause line pressure to drop and cause slipping or it will disengage altogether, the buzzing noise is most likely the pump.

Has the fluid level been checked?
Do you know how long it has been since the filter was last replaced?

Customer: replied 10 months ago.
The car only has 30,000 KM on it. No the filter has never been replaced. ( The motor is fitted with a Procharger )

Has the fluid level been checked?

Customer: replied 10 months ago.
No dip stick. I'll start by checking the ATF level.
Expert:  sprinkles08 replied 10 months ago.

A scan tool and dipstick would be needed to check the fluid level.

If the fluid level is good then I would next recommend removing the pan to check for excessive debris, water, and replace the filter/fluid if nothing is found that would condemn the trans mechanically.
