|
Greetings All
I have a unique noise happening with my transmission on my 86 Westfalia. Subie 2.2 motor. Installed a Steedle rebuilt trans about 30k ago. A very comprehensive build (oiler plates, new gear carrier and wellâ¦pretty much new everything else).
Lately I am hearing a buzzing sound while coastingâ¦in gearâ¦.clutch pressed. It sounds like a faint whirring noise as I decelerate that stops once stopped. If I am in say second gear it is clearly more pronounced than if I am in say third so it is definitely in gear train. If in NEUTRAL no noise. If I am standing still at idle I hear nothing with clutch pressed or not. Shifts fine. No howls or whines at highways speed and in fact quite smooth.
This is a new one to me. A fellow Vanagon group member has allowed me use of a good used trans while I get this one dialed in but wondering if anyone may have experience with this type of symptom.
Thanks!
Michael |

| Iâd reach out to Matt. Maybe record the sound. There used to be a German member that was very hands on with these transaxles. His experience was to go through them every 60,000 miles. |

Already did that. He is definitely going to help if needed. I posted this more to get an idea if there is potentially something ELSE I should check prior to bothering Matt with opening this unit up again.

What does the drain magnet look like? Pics?
Sometimes a 1st/2nd hub cracks, but seldom, thus often re-used.
You are 10 easy bolts from looking at the R&P.

| What about the pilot bearing? If I'm not mistaken, it seems like it might fit the described behavior. While coasting in gear the input shaft spins (at a different speed from the crank). Higher gears would have the input shaft spinning slower (less noise?). In neutral, the input shaft is not spun by the trans (no noise). No noise when stopped might not fit as the input shaft would be stopped, but the crank would not. |
