Have you ever had your transmission pan gasket go bad?

Question

my transmission is leaking pretty bad and its dripping at the back of the pan. i havent found any other wet spots except along the pan, would changing the gasket fix the problem? any other ideas? (85 el camino 5.0L-305)

Answer 1

If that is where your transmission is leaking fluid, then a new gasket should fix the problem.



There is a reason for the leak in the first place. Should you do the work, once you start removing the pan, pay attention of the bolts on that side of the pan to see if they are not as tight as the others. Also, once you remove the pan, check it closely for any damage. You could have "bottomed-out" and caused damage to the pan.



Should you, or a friend do the work, which is a very simple thing to do, you might as well change the filter since you would have the pan off. In one area, be careful, and that is overtightening of the pan bolts. The type of gasket you will need, which comes with the new filter, will probably be rubber based. So you don't want anyone who will power those bolts and tight as they can, which will cause damage to these type gaskets.



Very easy job. Just remove the drain bolt from the pan. Be sure you have a container to catch the flow. Once the fluid has been drained, have yourself a ratchet and start unscrewing bolts. When the pan is removed, what you will see in the transmission is the filter you also want to change. Make the change, line up the gasket onto the pan and bolt it back down, with the drain plug attached. Refill your transmission and you're finished.

I have owned many chevrolet auto and trucks and in my experience about the time the pan gasket starts to leak is when its time to service and replace the filter and pan gasket anyway. Its important to prepare the surfaces correctly and make sure they are clean of any old sealant and to check and straighten the edges of the pan if needed. Some people do not put transmission pans on correctly and overtighten the bolts, this can deform the pan slightly and cause premature leaks down the road. All it takes is to get the bolts in finger tight ( I was taught to put the bolts in from the middle, and then work out to each end. ) and then snug them up just enough so they will not fall out.

And when changing the filter to be careful and keep an eye on the bolt hole where the screw went into when taking the filter off, it is possible to do it wrong and it will damage the transmission eventually too. because it can cause problems with correct fluid pressure and cause premature failure.

yes you have to swap this out for a new one,and make sure when you do it you clean all the old gasket off the transmission and the pan itself with a puddy knife and take notice there is a magnet in that pan that picks up any gear shavings and you may see some rubber shavings there are some transmissions with belts in them.to much of any of these things in the transmissions pan is not a good sign.and make sure you check your transmission fluid with the engine running so you know its full again.and you know that you should aways check your transmission fluid with the engine running and the smell test is a good way of telling if your transmissions in trouble you can smell that burnt smell right on the dip stick itself.as fluid gos check with the auto parts store.now you can just go to sears auto and have them swap it out for you.at least they will give you a price up front.they have all the right tools and a lift,good luck with your ride.

Answer 4

replacing the gasket should fix the leak if the pan is not warped. before replacing the gasket use sealant on both sides of the gasket. myself i always use ( indian head ) shellac. that stuff will hold anything. it comes in a small brown bottle. auto zone sells it.

Answer 5

could just need re torquing. but yes the gasket will over time "dry" out and leak. change it out and replace the filter as well should take care of the prob.

I hate to be the single to tell you this, yet its no longer good. i might do away with that vehicle in a rush. Its a undertaking vehicle to start, and hyundae's interior the ninety's and early 2000 are no longer stable in any respect. the place are you placed?. i'm getting clues which you should be in a undeniable state and section. whilst you're in that section, i understand somebody which could help that owns and operates a save that i will deliver you to so as which you arent getting ripped off anymore.

Answer 7

It should stop the leak unless theres another leak somewhere else good luck
