98 Caravan Transmission

[jodiz]

Ok GTP Dad, the sound does get louder when I rev the engine. Earlier today again the gears were not reponding.
When it shifts though the sound goes low again.

I thought that perhaps there is too much trans oil. you see when the mechanic changed the trans filter, he ask me to put a couple more quarters. I heard that this could prevent the converter from cerating enough preasure (?)

[GTP Dad]

That is true. If you overfilled the transmission then you need to remove the excess fluid immediately. The extra fluid will damage the transmission and is probably causing damage to the front pump that is why you hear the whining sound. If you remove the excess fluid and the trans gears fail to respond then you have probably already damaged the internal clutches of the transmission. Also what type of fluid did you use? For this model transmission only ATF+3 or +4 should be used. Some of the old time mechanics like Dexron for Chryslers but that only causes problems.

[jodiz]

I used the ATF+3. What is the easiest way to remove the excess? DO I have to bring down the pan? I also have the feeling that when the mechanic "flush" it may not have done a great job because when I examined the dipstick I notice droplets of vapor towards the top.

[jodiz]

Ok so I took about a quart and now the level is where it is supposed to be. Should this take a while so that the converter builds up presuure (?) again? or should I get results right away?

Any ideas? I went around the block a couple of times and the whistling noise is still there.

Any thoughts?

[GTP Dad]

The converter should not be a problem since as long as it is full of fluid it will run silently. I hate to be the bearer of bad news but you may need to replace or rebuild the transmission. It is possible that water got into the tranny and damaged it internally. it really sounds like the front pump in the transmission is bad. That is the reason you are seeing moisture on the dipstick and you are hearing the noise. I would make sure that the noise is not coming from another area such as a misaligned belt, a vacuum leak or even bad tensioner on the engine.

[jodiz]

Oh man! you are the bearer of bad news and I tell you why I think so...when I drive the gears don't engage properly, sometimes it takes longer than others, sometimes I accelarate and there is no response, as if I was in Neutral.

Really scary stuff uh?
