URGENT!! Tranny Making a Wierd Noise

deadmic8 · #1 03-06-2005, 10:19 AM

Folks,

This morning following a very jerky shift to 2nd gear, the Auto box now makes a strange noise - like a pump trying to push air. a noise that sounds like a cog or bremmel on high speed the noise appears to speed up and down by itself while driving, Noise clears when idle or if you take it out of gear when driving in forward motion in 2nd,3rd and 4th. All gears work ok at the moment. Engine does not appear to be causing this noise

I have just had the truck up on axle stands and in gear, at low speed it appears to be ok, but when reaching 2000 rpm the noise appears to be coming from the pan somewhere.

Is this something anyone has seen or heard of, I am not sure if to drive the truck as this may damage something

I am in the UK so a investigation into the noise must be planned well ahead as sourcing any spares will be a challenge, any advise will be appreciated !!

What may be the cause of this noise ? -

please help !!

Did you check the fluid level? Sounds like it is low and sucking air.

I dunno, sounds like maybe the filter came out or something. Did you dent the pan by any chance?

Checked the pan from the outside no damage, I was considering taking the pan off for a inspection to see if anything has come adrift, however I am not sure what bits I need ?? On the underside of the pan it says something like - this pan has a reseable gasket- if this the case then I will have a look, if not I have will have to order the part from the US, which can take 3weeks if all is well...

Not sure If I can drive the truck or not (i use this to get to work)

You will need a 10mm socket to remove the pan. If you buy a filter kit reuse the stock gasket. It is the best gasket available.
