[Shop-talk] Manual transmission issue???

[Moose]

Braintrust,

I don't mess with transmissions at all, so I'm in the dark here. Hopefully 
someone has the answer and it's an easy fix.

The issue,   2017 Jeep Patriot with a 5 speed manual transmission makes a 
'whirring' sound when driving in 3rd gear or higher.

Started about a year ago, when car was picked up from a franchise mechanic 
shop.  (owner of car is a single woman without much money.) 

When she called them back they where like, "Well, we would have to charge 
you to look at it."  So since she already suspected they caused the 
issues, she didn't want to give them more money.

She brought it to another shop and they said, "You need a new 
transmission."  That will more than likely exceed the valve of the Jeep. 
So they just did a fluid change, and that was it.  Note, in their carfax 
report, they listed that they "installed a new transmission" in addition 
to the fluid change, so I don't trust them either.

It's a manual 5 speed.  I checked the fluid level and it is exactly where 
it should be.  So I did a road test.

Here is the crazy part.
There is NOTHING that I can feel that would indicate any transmission 
problems.  No slipping, no chucking, it shifts smooth and pulls strong. No 
vibrations.  The only thing is that noise, and that ONLY happens when you 
give it throttle.

So if you are going down the street at 50, and take your foot off the gas 
pedal, noise goes away. If you just give it a little gas, noise returns.

If you have it in neutral coasting, no noise.  If you are engine braking, 
no noise. The noise is ONLY if you have your foot on the gas in the 
slightest.

Note, there is also no noticeable noise in 1st or 2nd gear.

I am thinking that the original shop did something to the car to make it 
start this noise, knowing she would take it back there to get it fixed and 
that it's a simple fix.

I would love to be able to fix this as it is a hard working girl that 
doesn't have much money and really takes care of her car.  She is also a 
good friend of my fiancee, so it would be bonus points for me. 8>)

Thanks and I hope everyone takes a moment to think about all the Soldier's 
that gave their lives to protect our freedoms, (no matter what country you 
are from.)

Have a great weekend!

Moose
