Over Memorial Day I did a 325 mile trip with a buddy in our Series 2As. About 5 miles from home my truck made a new noise, sounded like it was from the tranny. Not a growl, not a squeal, kinda something between the 2. Just for a second or 2 then it stopped. Did it about 3 times in the last few miles headed home. Truck is shifting fine, clutch feels normal, just like always. Below is an E-mail I sent to my friend for a little more background. New gear oil is 85-90 Valvoline. Any ideas or suspicions? Truck is a '64 Series 2A, 2.25 gas motor.
I changed all my 90 wt fluids a week or so ago. The noise my gearbox started to make just before I got home from the trip is quieter but I still can hear/sense something different/new. The fluid that drained out of the gearbox was clean looking to me but I would guess that it was only about 1/2 as much as should have been in the tranny. So the level was low. I only took the QM out for a short test drive after the fluid change to listen and see if the new noise was gone. Maybe 5 miles or so. The QM is shifting fine just like always. What do you think I should suspect? Syncros, bearings, gears??? Do you have some time one day/evening to take a short drive and see/listen to what's going on? I don't know if I should run it and things are OK or if I need serious help before something serious happens. Please advise.
Thanks
