Running rough AND leaking trans fluid...WTF?

[patrick66]

I went to take a drive in my '66 Coronet 500 to celebrate its 50th birthday - yup, it was built 50 years ago today, September 1st! My son and I were going to take it out for a spin, and I was going to let him drive it for the first time - he's been bugging me for six years about it. Get it started and it was idling for ****, like it was running on six cylinders, but there was not backfiring or any of that; it just sounded like crap and ran terribly. OK, so I'm thinking plugs and some fresh gas, no big deal. I back the car out of the shop and see a pretty fair-sized puddle of ATF on the floor, and a drip trail back to the car. C'mon, already!

I pull back into the shop, and it looks to be coming from the front of the trans; meaning a busted converter or the front seal gave way.

I think I have a handle on both problems, but damn, this really pissed me off this evening!

Sometimes the trans could be leaking from elsewhwere.Unless you see a trail coming from the converter area,look closer.
My park cable is leaking and it runs down looking like the pan is leaking!

It was dead-center from under the bellhousing on the trans, so I'm figuring front seal. It was a pretty good-sized puddle that wasn't there until I started the car. I'll know for sure once it's out of the car. Nice thing is that I have a fresh spare that is sitting off to the side that I can install, along with a new converter; all which I was going to use in a future build. Downtime will be at a minimum.

That sucks sorry to hear about your issues, nice to have a spare tranny though, did you figure out the mis firing?

I'll second the WTF. At least you didn't have a flat tire too.
