Am I going to kill myself with this DIY

I found out that the detent pin caps on my 5-speed manual are leaking. For now, I am going to just top it off and not worry about it, but I hate leaks (OCD).

So I know the parts are cheap, but I would have to remove the transmission to do the project, which I feel that I could do. I am not a seasoned mechanic, but I am patient and have done quite a few repairs so far.

The question is whether it is insane to do this project. I have only jackstands, no lift, so I would have to drop the transmission, remove it, replace the pins and caps, then replace it. When I think about it it seems daunting, so I thought I would ask more experienced folks what they think.

Thanks in advance

Alone without a trans jack is dangerous. Two strong people is doable, a 3rd just to undo the final bolt is helpful.

I've removed my trans alone twice. Even with all of the bell housing bolts off, the trans wont simply fall off. You'll need to pry it off and essentially drop the trans onto a jack. I like to put the drain plug part of the trans on top of the jack. After that, simply lower the trans and out it goes. Seems simple huh? Disclaimer: Don't do this. I'm not responsible if you break or cause any bodily harm to you or anyone else. Have someone else be there with you.

Can you fit a trans jack and get the transmission to clear while the car is on jackstands?

Not sure about the footprint of a trans jack, but if you can't get your car to the highest notch of the jackstand (not that its needed) you need it at least as high as the trans itself. Once you get the trans on the jack, you can tilt the trans off the jack and onto a towel or moving blanket on the floor. After that, you can slide the trans out of the car. Thats how i've done it

yes i have this http://www.harborfreight.com/automot...ack-61232.html

useful when removing as it supports it but when reinstalling pretty useless to me as i couldnt get the angle right and height right.. I just lifted my transmission instead (5 speed w/o fluid) and put it into place.

i would buy this instead and it looks much better http://www.harborfreight.com/automot...ack-60234.html

If you can bench press 100lbs, then you can do the tranny yourself. There isn't a lot of room when working under jackstands so I removed the bolts and basically dropped the transmission onto my chest (slowly), then rolled it off my chest onto the floor. That's the easy part, bench pressing it back up and lining it up without getting tired and dropping it on your forehead, that's where the challenge comes in.

Removing transmissions on jack stands in the driveway sucks $&@"! I would recommend assessing how much it's really leaking, and how long before you need to do other work in the aria, like clutch stuff.

That sounds sage. I already had the clutch replaced (before I got bold about DIY), so I think I will wait for the rear main seal to hemorrhage.

I just dropped the transmission on my 330xi few day ago. I bought the harbor freight transmission jack and lifted my car about 16-18" off the ground. That was plenty to clear the transmission..

If you had clutch replaced recently, I would hope you would not have issues with your exhaust bolts and the tranny bell housing bolts. That was the challenging part for me removing the transmission. The four exhaust bolts pretty much snapped.

Which jack did you buy? And how long did the job take (I assume you were doing the clutch)?

I bought the one that is listed for 160. I haven't put it back together yet. Waiting on few parts.. and yes, for clutch replacement. The TOB was shattered.
