Default Tranny drips

I have not driven my Shark much lately and I noticed a few drips of transmission fluid in the garage. I snugged up the bolts as it looks like a leaky gasket. However, after a few weeks, still getting a few drips.

Guess I need a new gasket. Looks like a pretty straightforward job.

Anything I am missing or should look out for?

Thanks in advance!

From what I can remember, it's pretty simple and straight forward. When I did mine I was changing all the trans fluid. I forgot to get a new seal ring for the torque converter drain plug and every now and than I get a drip from there (when the plug is park in the down position).

Hey Jerry,

mine does the same if I leave it sitting for more than a week. I have a new gasket and the pan is properly torqued. It would seem that when the car sits for awhile, a few drops come out of the overflow, follow the edge of the pan and pool on the low point.

If the car is driven regularly, nothing at all.
I wouldn't worry about it, unless it's more than a few drops.

So this has been discussed for a loooong time, when unused the transmission fuild starts to drain from the torque converter to the pan. The fluid level in the pan rises creating pressure where it wouldn't normally.

There is a valve in the valve body which prevents fluid from draining from the torque converter but with age it seems to not hold as well which may help expalin why on some cars it takes longer to leak than others.

Fluid tends to leak from the cap on the resovoir, it is very deceiving but believe me it does, there should be an o-ring in the cap to prevent this. Most do not have the o-ring and it does not come with a new resovoir. Infact the o-ring is not much cheaper than the resovoir.

I have a tranny leak as well, but it is from the hose banjo fittings. I have replaced the crush rings, but the pressurized lines are leaking back where the fitting is crimped to the hoses.

This is an easy fix by just removing both lines and having new hoses made....I just have been too lazy to pull them and get it done.

The other notorious tranny leak that most folks experience is the seal at the converter. This is a rather inexpensive part, but to get to it is just not worth it unless you have to take the tranny out for some other reason. This one, you just have to live with.

One thing to make sure with the tranny pan gasket is to not crush the gasket. I have seen several auto's with the pan torqued out. When you replace the gasket at service, install with tightening the bolts alternately around the pan in increments until the proper torque is reached.
