Gents,
Here are a few pics from recent work to inspect/change the filter and fluid in the 727 trans of my '73 340 auto Rally Challenger. The filter was about 1/2 covered with very small bits of metal similar to what is visible in the bottom of the pan.
Car has 92K original miles w what I believe to be the original engine(block and head serial numbers are correct for the year) and transmisson. (This might be the first time the pan has been removed?) I've owned the car for ~2-1/2 years and the engine runs clean(uses nearly no oil btwn. changes), plugs run a nice tan, & pulls well; the trans shifts fine but is sometimes a little slow to engage into gear when shifting out of park/neutral. It might also slip slightly under hard accel. in top gear, but car will lay 2 healthy black marks from a standstill with no slippage.
So,...
(1) should I be concerned about this level of metal contamination since the trans. works O.K.? I expect this is clutch wear but I have very little experience in working on/troubleshooting trans. problems.
(2) I think the trans is also emitting a smell like lightly burning rubber/oil at higher rpms or just after accelerating hard. Is this a routine type of odor for a well used/worn 50-year old trans? Or could this be a small amount of blow-by from the engine? (engine has a Stock-type PCV connected on the driver's side valve cover; the pass. side cover just has a 3" dia. pleated filter installed for venting.)
I have been troubleshooting this odor since shortly after buying the car. Have gone through all the wiring & eliminated various other possible sources. I am using a 600 cfm edelbrock carb that I got from a friend that was lightly used and seems to work fine but I haven't tried swapping it out to see if it is running too rich for some reason. Any ideas/advice is appreciated.
