Here's a good one. I have a 1980 Chevy K10 4x4, it has a 350 engine and a TH350 transmission. Originally thought to have the industructable TH400. Anyway, my problem is a strange leak around the accumulator cover (just behind the dipstick tube on passengers side, TH350 only). I've never had a transmission leak there before. The fluid does need changing, it's dirty, but not burned. Should I reseal the leak and replace the filter and fluid or is this a sign of other problems?????
