GM OD tranny fit?
What would you call it, slick?
The OP's post asked about the GM tranny. He even stated that he was gonna get hate mail from others which you provided.
So what's with the "sounds like GM people" comment?
Or the comment about putting an LS motor in?
How many 518 swaps have you done? How are you keeping the driveline angles correct if you are simply dropping the tailshaft for minimal mods?
How are you controling the trans? Aren't you still modifying the driveshaft?
Just saying it sounds like the blind comments I see over on Moparts from their "expert" tools......
I see you have done 0 with a 518 or know nothing about it....
Again the only physical diff between the 27 and 18 starts right at the tail housing to main housing section... The only area that needs to make any room for the trans is right there and the next few inches back... and it's all right around the body cross and the trans cross member
What angle are you changing..... The mount is LOWER on the 18 vs the 27 or 04, so if you do not cut and lower the mount location on the cross member then you would be changing the angle... IT's WHY you LOWER that section...
Then you just cut, narrow the body cross member section and reweld the top section back to it...
I have done 2.... You know what the worst part was, the welding burns...
Sorry the little sarcastic joke gets your panties in a bunch with the gm and might as well drop a ls with the trans in.... or just buy a camaro...
It would be easier to drop the trans with the motor, then buy the adapters, might even be cheaper that way....
Now the op is asking because he thinks it's EASIER, and i didn't see anyone instruct him correctly....
So let him know what he is in for playing with the gm trans... vs the 18..some cutting = 0 cost, some welding = 0 cost, a wire to engage the od...$ a switch $, the slip if he doesn't have a 27 and shortening the shaft..
Needing a flex plate and adapter housing = $$$ , checking it's inline, linkage = making, modifying. speedo = $$ , od engages with the need for a tv cable, trans lines....
Lets see, you get a 518, it bolts up to the motor, it should take 2 hours to modifiy the cross and body cross sections taking your time...
You shorten your shaft, if you have the 27 same slip, if not, a new slip..
Sure does beat the need for, flex plate and bellhousing adapters, tv's, internal balanced or ext and lines and whatever else im forgetting...
But you're right revhendo.... im talking him down a bad path....
Hate....lol im talking him out of doing something costly & dopey because people make it sound scary..... you're talking him into it...
You're also scaring him into believing it's a huge job to put the 18 in...
Might as well put a GV in it before the gm swap... then all you gotta do is drop the trans cross member remove the tail housing and leave everything else alone....oh and maybe need a hammer to make some room...
