whining sound when in gear

[crash]

hey guys.. it's always had this sound since I got it (on the 99). assumed it was normal. lately, either it's starting to bother me or getting louder, one of the two.

in P no whine, in any of the forward gears I have it, and in reverse I have it. N - not so much

any ideas what this might be? this is in gear NOT moving. I mean it also has it when moving but I wanted to clarify that it's not any worse while moving. just with foot on brake in gear.

ideas? .. it almost sounds like a pump when it first starts to whine. trans fluid doesn't smell burnt, it is a tad less red in color and more transparent than normal, I think

thanks

Sounds like the front pump in the tranny.

[crash]

ugh.. that sounds bad .. and expensive

what do i need to do?

[Smiliesafari]

I wouldn't worry too much. The pump can whine for a very long time before anything bad happens. The only remedy is to replace it.

[crash]

I don't even see said pump listed on rock auto to get a ballpark on price

i assume this is the pump your talking about smilie? if so it 205+ core at

[Smiliesafari]

That is correct. Most of the work in changing it is in removing and replacing the transmission.

[crash]

well then... thanks for that guys. looks like i'll be installing a louder radio

[Kidhauler]

Darn you beat me to the punch line. I was going to say turn up the radio and wait for a bang

[crash]

LOL.. well is the pump a common problem? i've never heard of it going before, meaning never seen any posts on it.

would a fluid/filter change help at all ??

[Smiliesafari]

No, not common but it does happen. As with every mechanical devise there is a point when it wears out. Changing the fluid and filter never hurt a transmission but in this case it wont cure a mechanical problem.

[crash]

thanks smilie .. i'll save my pennies on that then... lol

I had the exact same symptoms after I rebuilt a transmission in my van once. Turned out to be the torque converter. Only made the noise under load. Park and Neutral were normal. I would think the pump would make the noise in all selections.

Hm I wonder if that's the cause of my whining too. If it was this pump, would the whine be louder going uphill, and in a turn?

so, in your opinion, is this something that one could just live with? would any type of additive help?

very good point about the pump pumping in all selections i am low on the knowledge about transmissions
