90 lumina euro - remove trannie?

Question

Hi there,Posted several months ago regarding how the reverse quit on my 90 Lumina Euro(sedan).3.1L V6 with 4T60 transmission131000kms.Basically, you guys confirmed what the tranny shops had already been tellingme... the trannie is shot!Sooo, I got a different one from another 1990 lumina with the sameconfiguration at the auto wrecker.Went to remove my old transmission yesterday... Is there some kinda trick togetting the H-Frame to come down?  I couldn't get any of the mounting boltsto budge!  Had a 650 ft-lb big bertha impact gun on them.... jacked the carup on the H-frame to try and compress the rubber in the mounts on the 4corners of the H-frame... they would not budge.Any ideas?  am I missing something here?  I put it back on 4 wheels (nodriveshafts are in the transmission right now, I am planning to tow it to ashop if I can't figure it out...)t

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3DMust be rust......cuz you're using the correct technique.Or your gun is no good.Might try rattling the bolts forward and back with the gunto see if it works.  (tighten..loosen..tighten..loosen)Sometimes that's all it takes.Other than that....the "Blue Wrench"(torch)~:~MarshMonster~takes a toke.....wonders if your impact gun cost over 300 dollorslike his did.......and if you do trannies for a liven like he does~~:~

Nothing wrong with the gun... but the air supply is a different story. Will be bringing the car to my buddy's place, he just bought a $2200 compressor, it runs 3/4" air lines.

The gun was over 300, its a Mac.... My bro-in-law used to do big truck trannies for a living...

I live in a rust area.  The bolts are rusted and seized.  Hours using impactboth reverse and forward yielded no results.Kjun wrote:
