Thread: So what does a 4HP22 sound like when on the way out?

Hi all
As I say, what does a 4HP22 sound like when it's heading for the great auto trans graveyard in the sky?

I have to admit, I haven't yet had a good listen and crawl around while running, but I have a constant whirr/whine when running that rises and falls in pitch with engine speed.

It doesn't sound "mechanical" enough to be the T/C, the back to back seal & output seals were done in October/November last year so I don't think it's that.

Just wondered if the A/T starts making any noises like this before it goes to lunch. Larry's done 273k km and the PO had a 2nd hand one put in not long before I bought him at 160k km.

Cheers
Mike

Thanks Scott, nothing I can really put my finger on but I was thinking pump/torque converter. From standing, when I put my foot down the noise becomes quite noticeable, too quickly I feel for mechanical gear noise, and is present during driving. In fact quite intrusive...
I'll have a good look around on the weekend. Would really like it to be something else, need to spend the cash on the County!!
Cheers
Mike
