Transmssion Seized to Engine

[MikeRamTB]

Have read of many who have removed the tranny and have found it to be seized to the engine. Apparently the dowel pins get corroded due to the disimilar metals. Can anyone share any tips on how they got the tranny loose from the engine. I have only read one person who managed it by heating the dowel pin area, but it was not a trailblazer. Don't feel too comfortable with a torch under that tight a space. Mine is a 2003 TB 2WD, have removed 11 bolts, plus the 3 converter bolts. Can't make it move, nor see anyway or location fit for prying. If anyone knows where the dowel locations are, please share in case heating is the only option.
Will appreciate the support.

i would think that if you put a jack under the rear of the oil pan to support it, then tugged down on the tailshaft that it would start separating just due to the weight

I'm not 100% sure about the I6 dowel locations but here is a pic (on the right is the I6 bellhousing) and I think they are probably at the 3:00 and 9:00 positions

It's the one on the right with the starter on the driver side. I would agree even though I don't really see a hole for the pins. Other bell housing pics I have don't show the pin holes either. I put a jack about 4 inches below the tranny pan and let it hang all night to see if the weight did anything w/o luck. I also tried some PB blaster even thou there is no real place i could find to seep anything in there. Since all instructions say to just pull it straight back, I even tried a come along pulling back from the steel tail mount. No luck yet.
If you know any other sources that could share some insight, all is good. Thnx.

Hooray, Got it loose. The key is to restrict the movement of the engine which absorbs all the shaking via the motor mounts, so I locked the engine with a jack. Shook it sideways then removed the support jack as to not interfere with the tranny and then move up and down letting the weight assist. Since the engine was locked it could not absorb movement in that direction and finally cracked about an inch. That's more than I needed. BTW, motorcycle jacked worked great as a tranny jack. I just place a square board under the tranny pan. The 2 dowel pins are rusted and are hollow pins allowing the bolts on 10 and 2 o'clock to go right thru them. That explains you can't see a hole on the bell housing bolt pattern. Thanks.

Try to give it a blow with a deadblow sledgehammer or a copper sledge, you can also try to raise it in the back instead of lowering it and at the same time give it a couple of good blows with the sledge .

Edit: never mind, you got it loose. Nice work.
