Well I replaced my rear tranny seal today. But my pan gasket leaks.. the trans is a th350. Im not sure if its original or not. It is sitting on a new trans mount( if it makes a difference lol). The trans shifts great and pulls good.. a friend of my said I could burn it up with the fluid and filter behind changed. I know it could happen, so sometime soon im gonna replace the gasket and fluid. Any precautions I should take?

If the trans is in good shape....The fluid & filter will not hurt it.
If it's hanging on by a thread....It can go out any day

Ive heard of it tons of times where the trans just ups and quits after a fluid & filter change, don't ask me why but it does happen. In fact it just happened to a friend of mine in his 97 chevy, never had a problem out of it... changed the filter & fluid then a month later BAM it wont go into gear.

I think I'll just stick with my manuals!

A worn out transmission will do this, But maybe it was going to happen anyway??

My tranny works real good. Im tired of it leaking.. Im unsure of its maintinence life before I got it so im assuming it hasn't been serviced.
