Anyone know how to replace the rear main oil seal?

I figured it's time to do it.

You'll have to remove the transmission, and on the 3.0 the top bellhousing bolts are a pain in the a$$.

if its not leaking, its not worth doing. 300$+ job for a 3.00 part. If you paid to get it done.

Oh its leaking. About 2 quarts every 3,000 miles. More so on highway trips than normal commute.

I need to check a few more places but I'm 90% sure it's the rear main.

automatic tranny huh? maybe a tranny seal or something. im not sure bout autos, but if it was a stick shift, id say check your slave cylinder, rear main, front tranny seal, and input shaft seal

Ok so the rear main is def the culprit and now that I cleaned my garage it is prime time for auto work.

So what exactly will I need to do?

I can rent a tranny jack, but what else?

Would I be better off getting a shop to do it?

Only you can answer that question.

I'll tell you this, R&R a transmission is a lot like work. If you have fairly solid mechanical experience, you will be fine. If you need help changing spark plugs, you will want to leave it to a pro.

It's just impossible for us to know what you are capable of, but most people who are capable of a project of this magnitude wouldn't need to ask. I'm not trying to be a jerk here, but doing this type of work can be dangerous if it is not done correctly. I know of one guy who was killed by having a tranny fall on him and another that crushed both of his hands with a tranny jack.

Whatever you decide to do, be safe.

If you are not 100% confident that you can pull that tranny out without it falling and splitting your skull/arm/back/crotch in half, then don't do it. The auto trannies are H E A V Y, and even with a good tranny jack they can get away from you.

If you do decide to do it, get a good jack, with good safety chains, and have a buddy there to help you. Preferably one who knows what they're doing.

I don't need help changing spark plugs :p

I'm confident that I can do it with my buddies, and safety will of course be the main thing.

I do understand they weigh upwards of 900 lbs, and for that a good tranny jack is needed.

I just need guidance, I'm not about to go into this (or most other things) with out first checking proper procedure, just as any mechanic should be, always making sure it is the proper procedure.

Make sure you get the torque converter bolts out and slide the torque converter back as far as you can in to the trans. It needs to come out with the trans. If you decide to replace the front trans seal while it is apart measure the depth of the torque converter in the bell housing first so you can make sure you get it all the way back in. It is a common mistake to not get it right and trash the transmission.

A long extension like 36" and a swivel socket will make the job easier.
