Thanks Chevelle SS 396 L78 .... I did remove those springs as the rear of the car sit up to high.
Missed going to the muffler shop last week because of a very heavy rain - so now I have an appointment for this coming week

I got the exhaust fixed at the muffler shop the other day so the car is much quieter now, but still has a pretty good rumble.
Next the transmission shop to get the leaks fixed. Trans did shift fine on my trip to the muffler shop.

I've got a sit-back as the new kick panels leak. Looks like I didn't get something right.
I'll have to try it again or get someone else to try. And I hate working on these things

The transmission shop I was going to have fix the leaks on my transmission never called, so me and a friend with a car lift worked on it.
After getting back home there was no leak for 5 or more hours. But after sitting for more than 12 hours, I did still have a leak. I think the converter must have drained down and the pan gasket is leaking.
So I've got a new gasket - and we will try again. If anyone has any great ideas on how best to seal a pan gasket on the trans - please let me know. Thanks

I always use Permatex #2 between the pan rail and gasket, and nothing between the gasket and trans case. Has always worked well for me.

Be sure that it isn't leaking from the dip stick tube. Your pan gasket may be fine, but the O ring on the tube may be the problem.

Thanks for the helpful replies. I have been checking to see if there are any leaks/drips or signs of any red fluid coming from anything above the pan gasket and transmission body parting line.
I've ordered an RTV sealant Permatex makes just for auto-trans. Hopefully I'll get this fixed soon

Looking again this afternoon I don't see anything on the shift linkage, nothing on the vacuum modulator or running down from the dipstick tube, and nothing running down the front of the trans case behind the torque converter.
So I will try the RTV between the pan and the gasket

Good luck! Also check that the flange is flat and not rippled from having been overtightened.

I found the source of my trans leak and got it fixed. There was NO seal on the shift lever shaft. Grime, dirt, gunk, grit, but no seal - not even a piece of old seal - nothing.
So it now has a nice new seal.

How about the SCR in Bowling Green ... wasn't that fun. I know I enjoyed it.
