replacing AT tranny, what else should I do while it's out?

Featured Replies

Hi again. I found a same year AT replacement for my '97 Outback with the blown front differential. It's out of an Outback with 90k that was hit but was still driveable when parted out.

I have the transmission sitting in my garage and am in no hurry so I'm wondering what else should I take care of either while the "new" trans is in front of me or while the old one is out?

An example being the rear seal that seems to end up leaking.

Anyone's ideas are greatly appreciated!

 

PS- I'm having a local shop do the actual swap since it's relatively easy for them with lifts and trans jacks etc. plus they've done it lots of times before. I'd like to do anything I can ahead of time and provide them with the parts for anything else.

The oil seperator plate (the plastic thingy) if it hasnt been replaced. They leak like sieves. The replacment is a metal part.

So what do mean by New trans....? Don't you mean a 90k used trans..?

If I read that post correctly...

 

I would get it rebuilt if it has 90k since you have no idea of the maintainence or how they drove it. Install a trans cooler...it will last longer!

Yes, it is a used transmission. That's why I put "new" in quotes...I probably should have called it the replacement. It was pulled from a normally running car that was rear-ended and totalled with the insurance company, given a salvage title and bought by someone near me who needed the motor, driven to his house etc. and I bought the tranny from him at his house.

I think a rebuild would be overkill considering the car has 200k on it and was bought for 1000 dollars. I'm not ready to dump 2 grand into the beast with that mileage and that's what I was quoted for a rebuilt and install here. The Outback is in decent shape other than the diff being bad. The trans cooler is a good idea though! I can do that one myself.

 

What I'm wondering is what items are easy to replace while the transmission is out of the car...what things normally wear and leak etc.?

There's an oil seal around the front input shaft of the trans. I learned the hard way to always replace that seal when you have access :rolleyes:

I suppose it's the same with a manual trans. To bad I did'nt know that before now. How long does a trans front input shaft seal last normally. My car has 150 K miles. Since there is no pressure behind it and that the trans is tilted upward some, i guess it can last a long time. ???
