Addicted To Boost Posted October 18, 2006 Report Share Posted October 18, 2006 I'm no genius when it comes to auto trannies, so I'm gonna need some help here. Lately, when I go out and drive my TGP, for about the first 5-10 minutes of driving while the engine and tranny are cold, it sounds like the tranny is whining and it is fairly loud. Coming from a stop and accelerating when engine/tranny is warm, the tranny will whine, but it is very quiet whining. What could be causing this? The tranny in my TGP only has about 12,000 miles on it. Thanks Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted October 18, 2006 Report Share Posted October 18, 2006 How's your fluid level? It's possible that the transmission fluid pump is worn. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 18, 2006 Author Report Share Posted October 18, 2006 My fluid is at the full mark and the fluid is bright red, smells normal also. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted October 18, 2006 Report Share Posted October 18, 2006 Did this whine just happen or has it always done this? Is it getting worse? Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 18, 2006 Author Report Share Posted October 18, 2006 I just bought my TGP on July 31st, started driving it a little bit in September. I have only put on about 1,000 miles since I bought it, but it has always whined quietly since I bought it at low speeds (40 mph or lower). Lately I have been noticing it, because of the colder weather (40-50 degrees F here right now) as it gets colder, the more noticeable (louder) the whining gets. It is only loud when I first start drivng it for the first 10 minutes (cold engine). The rest of the time it only whines quietly. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 19, 2006 Author Report Share Posted October 19, 2006 Any other ideas to what might be causing this? Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted October 19, 2006 Report Share Posted October 19, 2006 I dont have any more, but I dont think there's much you can do. Fluid is good, it shifts fine (I'm assuming), thus no symptoms of anything except the whine so it's really hard to diagnose. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted October 19, 2006 Report Share Posted October 19, 2006 For as far back as I can remember, the 440T4 in my GP whined incredibly loud. It lasted 180,000 miles though, so I guess whatever caused the whine wasn't hurting anything. Quote Link to comment Share on other sites More sharing options...

ONE THING I FORGOT TO MENTION: when the tranny is cold during the first 5-10 mins of driving, when I get it up to speed where it should shift into OD, it is REALLY slow to shift into overdrive. Not the shift itself, but I can just be steady going at about 55mph with 1/4 throttle and when the trans. is cold, it takes about 10 seconds of steady speed before it decides to shift; or if I take my foot off the gas completely, then it will shift. It only does this when it is cold. I dunno what is going on. Could all this be caused by a worn tranny fluid pump? Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 19, 2006 Author Report Share Posted October 19, 2006 Could the other problem I described above be caused by a worn tranny fluid pump also? Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted October 19, 2006 Report Share Posted October 19, 2006 I think thats normal. I know that the torque convertor won't lock up until the vehicle is up to operating temp. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 19, 2006 Author Report Share Posted October 19, 2006 Okay that is good to know. So does anybody know how hard it is to replace the fluid pump? Where is the pump located? Outside of the tranny or inside? Cost? thanks everyone Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted October 20, 2006 Report Share Posted October 20, 2006 its inside the transmission, i'm not sure if its accessable with the trans in thr car. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 20, 2006 Author Report Share Posted October 20, 2006 Anyone know how hard it would be to replace this pump? Quote Link to comment Share on other sites More sharing options...
Dark Ride Posted October 20, 2006 Report Share Posted October 20, 2006 Anyone know how hard it would be to replace this pump? Since Its Inside the Transmission, I'm going to say that your probably going to need to pull the engine and transmission. Then take the transmission apart, find the pump, then replace and put everything back together. I would honestly just ignore the whining, if everything else is running normal, it could be anything. If your really concerned about it, perhaps taking it to a Trusted transmission shop and having them listen to it might be beneficial.

Addicted To Boost Posted October 21, 2006 Author Report Share Posted October 21, 2006 Meh it really only whines noticeably when it's really cold outside. I drove it today and it didn't whine at all, so yeah we both don't like the cold. Quote Link to comment Share on other sites More sharing options...
