Transmission/Fans

Many of you know that I am not mechanically inclined.

My transmission whines when shifting. I use transynd in it and it did it before the transynd was put in. Not bad and the Allison folks said it was ok but to me it is very noisy.
The previous owner said it was just the Allison transmission changing gears. Do any of you experience this?

Also how can you tell if the two fans in the engine compartment are doing what they are suposed to do?

DriVer maybe I can get you to listen to the transmission at Bethpage..THanks

Tranny whine is a fairly common sound. It does not necessarily mean it is about go out. If you feel you have a problem then take it to a qualified Allison shop and have it checked.

The 2 fans in front of the A/C condenser are there to add more air when the A/C is be used and the temp goes up.

Thanks for the reply. I did take it to the Allison folks and they said it was fine..I was just wondering if others experienced the whine also.I believe this is a 1000MH which is a new tranny to me. The 3000MH had no such whine..Good Miles

My transmission whines....I just ignore it...Workhorse says it's normal...I consider it loud and when I read the Allison ads in Motorhome magazine about how "quiet" it is, I laugh...
