Hello,

I need some advice/help in regards to my problem on my truck. I brouhgt it to two mechanics: one telling me its my transmission and the other one not being able to identify the problem. The first one has always charged me more than the second one so I have my doubts about him.

Here it is: my car starts fine. However, when I am in neutral or just parked, the car runs normal. When I switch to drive or reserve, it starts making a loud 'whining' kind of soud.

Also, when I drive and I press the gas, the whining sound gets louder.

That sound has been there before, but now it has amplified to the point where you cannot ignore it.

I am concerned it might be my transmission? It would suck to have to pay for that if the problem does not come from it.

Please help.

Thanks,

Laurence

HI there,

Thank you for the donation,

This is sounding like a transmission problem, with out hearing this first hand does make it a bit harder to give a correct diagnosis, so I will suggest that you get your local transmission specialist to listen to this noise and possible have a test and report done on the transmission, that way you will know for sure which way to go with this repair, start here.

Hi Mark,

Thank you for the reply. I went yesterday to another garage that was a bit further from my house. I don't know it is weird but they do not run 'tests' on the transmission here in Canada.

They said it might be the transmission or there might be 'debris' in the torque that is with the transmission. So either way they have to open up the transmission for them to see.

Do you think they have to open it up or a good transmission specialist will be able to tell me about the problem specifically without having to open it? With the tests you are talking about I mean?

Thanks,

Laurence

I have a 97 and I'm to;d the power steering pump, which is hooked up tro the rack/pinion also. Take the timing belt off for breive moment and see if its still humming. If not you might get away with a flushing. Possibly replace the pump.

HI there,

A transmission work shop can do line pressure tests and electronic scans to determine many components viability, also by just removing the pan they will see any foreign material in the filter or on the bottom of the pan, this is a very cheap check, have this done.
