suburban 1979 - noise from automatic transmission
 

good morning.

I have a question regarding a very quiet noise when I start driving with my 1979 chevy suburban big block / TH 400.

It happpens not in N or P, only in D

I have checked the automatic transmission oil level. In P.
Hot engine. It is full.

Not when the car is running ... only when I start running ... driving.
also when I drive uphill.

Very quiet, sounds like "sucking oil" ...

Any suggestions?

Thx in advance, Stephan

solution: check the oil level ...

You may have to pull the pan and make sure the tube did not come out of the filter or the center bolt holding the filter up has allowed the filter to drop off
