Hey guys and gals. I have a 95 f150 that Im throwing an engine into, and the truck has sat with no engine in it for the past year, with the torque convertor not seated into place.

Do the front seals on these transmissions dry out or wear out at all from sitting like that? Truck was in a shop in dry cold storage, and didnt leak before hand.

Id hate to replace it if it was required, but Id also hate not to replace it than it leaks haha.

Just wondering what the general consensus was regarding this.

 

I don't think it will dry out. On the other hand, that seal is a known weak point on the E4OD. There is an aftermarket seal made from a material called Viton that is MUCH better than the stock seal. I recommend changing it.

 

Thank you sir, I will get one and change it.

Mark, would you also recommend changing the bushing as well, or just change it if necessary?

 

I'd change it, too. They are really cheap, and since you're already in there...

 

Sounds good man thank you, will order a kit off of ebay and replace it all, thanks very much for your input.

 

since your there and the seal is pretty cheap.just replace it.there's no need to replace the bushing if it's not worn.the cost of the bushing is no issue but you need to remove the pump,split it,properly hone the pump bore out for the replacement bushing and insure you re-install the gears properly and make sure the pump is lined back up exactly again.it's something best left for those who like to learn new things and have the time to learn them or a trans shop.

if you try it,don't pry the pump out against the thin case,or you'll turn your trans case into a boat anchor.also don't let the parts fall out behind the pump or else you'll be very sorry.
in summary,if the bushing is ok.don't touch it.if you want it changed,take it to a trans shop and let them change it for you.it's nothing at all like simply picking the old seal out and tapping it in in just 30 seconds.it's very a technical job.

 

Yes,x2. Good post/info.

 

Ok thanks, Ill take that into consideration as well. I have the engine pulled from the truck, not the transmission, otherwise I would just take the tranny over to a shop and get it done.

I was under the impression that to replace the seal, one would have to pull the pump anyways, but im guessing thats not accurate? Guess Ill ahve to look into that a little more as well.

 

no.you just pluck the seal out and tap another one in.a completely different job than replacing the bushing.they are close to each other yes,but the jobs to replace them are miles apart.
