Great recommendation. Where is he located? Any contact information would be greatly appreciated. Mike

I'm beginning to agree that these are not orientation marks, but then I found the following: From Ed Packer's book "Manual for Plymouth Owners", 1950, "When putting the piston back on the rods, the slotted side of the piston must be opposite to the metering hole in the big end of the connecting rod. When placing the rods in the engine, the metering hole must face toward the camshaft side of the engine." I have seen the slots in original pistons he is talking about. These new pistons do not have the slots so I believe I am pretty much worried about nothing. Thanks so much for all the responses, Mike Beyer

Photo of piston paint marks. Orientation?

Can a piston be put on the rod the wrong way?

Our new pistons have paint marks (dots) on the underside of the pin area on one side. Any idea what this mark signifies?

Thanks so much! Went to Redlines website and found 6 different ones to choose from.Any recommendations on which Redline MTL to use? 75W80?

What fluid is recommended these days for a standard/manual 3-speed floor shifted transmission? I know the service manual says 50WT engine oil but I am wondering if something might be better? I don't think I want to go synthetic.Our transmission is marked D-11 (1939?). Thanks for any input or guidance. Mike

Thank you. And the extra effort of crawling under your car. Will try something. I have never put anything back together that had something to do with internal combustion that didn't leak somewhere!

keithb7, Great advice. I made up the 3/4" oak dowel tool and I have both the bearings. Looks like the 1939 Transmission was a one year only deal. Will attempt to address that shaft leak issue. Did they leak in the front and back? Thank you bunches! Mike

Thank you! You are really helping me out with my lack of confidence in putting this rascal back together.

It is a standard, floor shift 3-speed with D11 markings on the back. Please don't go to the trouble to tear one down. I did notice on Ebay that the Transmission Small Parts packages from 1940-1956 do not include this large washer, but the ones for 1937-1939 do (see link below). The inside diameter is too large for any of the shafts or drives in this transmission. If it locks up when I get it back in I may need to buy one of your transmissions under the bench!

KeithB7, Thanks so much for the reply. Plyroadking knew what the rascal is and all you folks have now got me confident that I can get it back together and be prepared to put all of 97 horsepower to it without concern. Ya'll are great, Mike Beyer

Plyroadking, That is it! Thank you so much! I have never seen one. There was not one in my transmission when I tore it down, but noticed it in the exploded view in the manuals. The car has never run so I did not know if the transmission was functional. Good to hear that it probably won't make much difference in the functioning. Now if I can figure out what the washer/plate is in the attached picture. It came in a Transmission small parts package Part#939731. I have purchased the BorgWarner CD and the 1936-1942 Parts manual and still cannot identify it. I have research the exploded views of Dodge transmissions from 1936-1942 and still no luck. It is larger than the countershaft plates/washers both in outside diameter (2-1/8") and opening diameter (7/8"). It would be to large for the countershaft. I am attempting to reassemble a D11 1939 Transmission. Any guidance on this would be greatly appreciated. Thanks, Mike

I have given up searching for this part shown below and thought I may as well ask the forum before I put it back together without it and hope for the best. I have purchased the Borg-Warner Gear CD and the 1936-1942 Dodge Parts Manual. It is shown in the exploded view of the parts manual but not in the parts listing/ part numbers section. It appears to be a one-year only part. It is called a Synchronizer Stop Ring Spreader Spring and is #24 in the exploded view of a 1939 Dodge D11 Transmission. Any guidance would be welcome. Thank Ya'll so much, Mike

Can anyone out there identify this washer/plate? It came in a Transmission small parts package Part#939731. I have purchased the BorgWarner CD and the 1936-1942 Parts manual and still cannot identify it. I have research the exploded views of Dodge transmissions from 1936-1942 and still no luck.
