transmission problem coming?

Just finishing up spring maintenance on the 46. Oiled and greased and everything checked. I hadn'd chnged the transmission oil in 4 years so drained it out and refilled. Old oil looked good but after emptying the drain pan into my waste oil container I noticed a million eensy "gold" flecks in the film at the botton. Sort of like some of the new black paint jobs that have a sparkle in them except much smaller. Tried to take a picture but they really don't show up good. Could something brass or bronze in there be wering badly? Maybe only 6 or 7 thousand mile on that oil. Any guesses?

I'm far from an expert on transmissions, but I would expect it to be normal wear from the synchronizers. If they didn't wear there wouldn't be any need for replacement parts.
 
I agree with '40cpe,:) if the transmission is still shifting smoothly,it's not a problem.;) You only need to worry when you see chunks of gear teeth coming out of the drain hole...:eek: Ask me how I know, spelled Zephyr...:(:eek:

myself and a friend just built a transmission out of a 1941 "78" box and i looked inside and mine has 2 syncro rings(brass,etc)...if you are seeing flakes i wouldn't worry about it...if you are finding tiny teeth then you may want to repair but it sounds like its ok...someone else can pipe in and tell you the correct weight oil and amount...gump..
 
I just rebuilt the transmission for my 47. It holds about a quart. I put in straight 140 gear lube.
I agree with the above advise that if its still shifting ok and not making excessive noise while driving down the road.

Well, that's good news. The transmission shifts smoothly and is quiet. Just back from a burger drive-in. 45 miles r/t. Fish and chips and a clam roll for the Missus. Less than 2 weeks on her new hip and she is getting about very good with her cane.Thanks fellas'

John, good news on Barb!!

Now on the transmission, I am hoping Charlie, ny and MacVP might chime in here with their opinions.
 
John,
Thanks for the comments. I have been using 80/90 gear oil but will drain again and fill with 140 (summer) like Henry Ford says to use. Maybe the 80/90 does not lube as good in hot weather.

Ford recommendes 2 1/2 pints of 90 summer, 80 winter changed twice yearly or at least every 5,000 miles. That's what I do. The 80/90 you already have in is just right.

Re: transmission problem coming? HENRY

Henry,
You are right. I was looking at specs for the rear end. I bought some 85/140 so will use it in the rear end which has 90 now. John
 
I still think and have found that using the 140W in the transmission is a better choice. I have less leakage using the 140 than 90. As long as you don't drive in sub zero weather the 140 will do a good job for you. Don
