Transmission Removal

Cant reach top bellhousing bolts

Transmission Removal

Postby thrlskr [OP] » Feb 26 2012, 1:53am

My transmission is on its way out Decided to replace it myself, but have had several issues (frozen bolts, difficulty reaching parts and more metric bolts than anticipated)

Details: 2000 Sierra 1500, 5.3 l, ext cab, 4x4

Followed the manual and have been able to remove everything except the top two bellhousing bolts. Has anyone else had this problem? Is there a special tool that I need to have in order to reach them? They are under firewall, so cant be reached from above. I can see them from below, but there isnt enough space to fit a spanner. I am completely confused!

This is ALL that is between me and getting back on the road!

Thanks in advance

Can you take any pics of the location of the two bolts? Those would help a lot.

Not enough space to get a coherent shot with a camera. This is a diagram from the autozone web site. According to this diagram, there might be 3 bolts left instead of 2. I am referring to the very top of the bellhousing.

You also may want to get this as well, I think the nuts that hold the brackets on the belhousing bolts are 13mm: http://www.amazon.com/SKT-33363-Swivel- ... B000R7NM60. Sorry, I forgot about those.

Jordan,

Thanks a million. The tran bolts on mine are 15mm. I got them all off and removed the trans. just a little while ago. Still have two problems:
1) One of my flex plate to converter bolts is stripped and a cannot remove it. Going to try vise grips now that the trans is off. May need to cut it though.
2) The bellhousing torx bolts on the old trans are very tight. Just broke a T50 torx in one. GOing to have to either buy another or drill them off.

For the converter bolts, Try using a hammer and chisel to break them free. It will mutilate the nut, so you will have to get new ones (which you already have to, so, it's not a big deal). Once you get them broke free you can use the vice grips. Another option is to get one of these pair of pliers, they are great for getting rounded bolts off. The harder you pull the tighter they grip: http://www.channellock.com/410-NUTBUSTER-Plier.aspx

The bellhousing bolts are not regular Torx bits, they are a special torx bit. This is the one you need: http://buy1.snapon.com/catalog/item.asp ... ir=catalog
Good luck. After this job you should have a lot bigger tool collection!

Thanks again Jordan!

Yea, my tool collection is bigger LOL found other small stuff to correct, so am happy to be doing this myself.

Didnt realize they made a diff, Torx for this. Started drilling these out. 3 are too stripped inside to work with. The others are out.

Guy who sent the trans gave me all new bellhousing bolts so Im golden. With any luck Ill finish late tomorrow or friday.

I'd get the bit so you don't strip the new ones putting them back in.
