1970 300 - I put about 500 miles per yr on this car. Mostly driving around town so not much highway. Besides the 2nd to 3rd problem I think we fixed in another post, thanks to 413, thethee, cbody67...ok, i can't list everyone but anyhow, transmission never had a smell, odd color or weird sounds. I haven't changed the fluid in 20yrs (10,000 miles ). With just straight Castrol ATF+4, It was leaking for years around the shifter input and rear seal so I put 1/2 pint of AT205 sealer which worked great for such a little amount. No drips after that. I think I added fluid once about 10yrs ago. Looks like I waited too long but at 500-1000 miles per yrear, how long can I wait to change the fluid?
Old fluid that I took out looks and flows almost like new. I thought Great !, until I removed pan and saw this. Are all those black specks from the gasket? I know some crap is normal. Is this some? If its more than normal, anything special I need to do? I'm going to put ATF+4, new filter and gasket. I was thinking of adding 1/2 qt of Lucas transmission medic in it too.
Oh yeah, should I put a magnet inside like new cars have? If so where and what size? Thanks
