Can you hear your transmission shift?

2009, 112,000 miles. When driving around 20 mph, and gradually increasing speed I can hear my transmission shift into another gear. Makes a "clunk" sound. Anyone else hear this or is my transmission going up

 

Mine only clunks when I'm parked and pulling in or pulling out and even then its usually only on a slope. I'm at 156xxx. If it is loud enough to worry you, I'd have the trans. fluid changed and tell them to look for shavings.

 

Only when I push in the clutch.

 

No but I can feel it if I am thinking about it at the time it shifts.

 

Check your u-joints?

 

Assuming the op has an automatic . It would be great if he could give us a little more info .
considering its a 2009 we have to wonder if the transmission has ever been serviced knowing it has 112 k on the trućk ?
Also wondering if he has serviced his universal joints ?
Wondering what the op has tried to alleviate the clunk ?
I am sure he knows the transmission is computer controlled and can only be diagnosed with a scanner ?

 

no sounds only feel

 

Sorry, yes it's an automatic. Have had the transmission flushed at 90K. About a week ago I had to have the bearings replaced in a front tire and the service guy said he would check mu U joints and seaid they were ok. Did not know about the scanner, but I will have it looked at as well. Thanks a lot
