Can anyone suggest as to what the problem might be. When accelerating from a complete stop the engine revs louder than usual and RPMs hit around 2500. This happens for the first 2 gears but once speed has gotten to over 40 seems to run ok.

 

It could be a vacuum leak or vacuum hose that popped off. Check the hose that is connected to your air intake, this same problem happened to me when mine came off!

 

Or your fan clutch. The one on my old van locked and sounds like a school bus accelerating. Remind you of that?

 

Yes does sound like an old shool bus. I think you guys got me on the right track. Enough for me to sound like I'm know what I'm doing when taking it to the shop. Thanks!!

 

mine has always done that from time to time...esp in cooler temps.
never hurt anything...sounds like i am engaging a turbo!! if only

 

Yes the fans on these things are crazy.

 

You say it revs to 2500, is that normal or is this just since it started acting up?
If it's normal then check what they've suggested. If it's a new thing I'd check the trans fluid, sounds like it may be low & slipping or the torque converter is low on fluid.

 

Just starting yesterday morning.

 

Don't believe the RPMs are out of whack. But it just started making this loud rev noise and a whistle type of sound. Appears when it hits 3rd gear and on the freeway seems to run right and sound right.

 

funny mine does this once in a while , great way of describing it lol
