Chevelle updates

Never seen one of those transmissions. Looks to be built like a brick $hithouse! Let us know how it works out and whether it requires any floor or crossmember mods.

Looks like I *may have* found a potential problem that was missed when the Quicktime bellhousing was installed. Once I confirm I'll post the details so (hopefully) others won't overlook what I did.

I'm sure you will work your way through this &quot;potential Problem&quot; ...

I was right...one snuck by me.

When I installed the Quicktime bellhousing, I re-used the trans mounting bolts I'd used with the reproduction 621 bellhousing that was in the car before. They are 1/2-13 X 2&quot; along with a lock washer and one flat washer per bolt.

I didn't notice that the upper two holes on the Quicktime bellhousing were partially blind. When I installed the Muncie onto the Quicktime bellhousing, the upper two bolts just <span style="font-style: italic">barely</span> bottomed out before drawing the trans down fully tight. They were tight enough where no play could be felt, but I'm sure in operation there had to be at least a slight amount of movement. I did note that the broken ears from the Supercase were still <span style="font-style: italic">somewhat</span> tight to the bellhousing when the broken trans was removed, but they weren't fully tight.

I measured the thickness of the mounting ears on both trans', and the Legend box is notably thicker (exact measurements are out in the shop, I forgot to bring them in with me).

Below are two pics of the new Legend trans with new 1/2-13 X 2&quot; Grade 8 bolts along with a lock washer and two flat washers on each bolt. They are snugged down pretty tight, and as you can see they terminate just about perfectly out the back of the bolt bosses on the bellhousing.

Driver's side:



Passenger side:



Here's the mounting face of the bellhousing showing the clean-up skim cut it received on the mill after putting the lower passenger side mounting tab back into position.





As you can see, it was barely enough to remove the powdercoating. It's again parallel to .000&quot;

The clutch disc has been swapped, a new pilot bushing has been installed, and the bellhousing is back in place. I'll try to get the trans under the car tomorrow.

More to come.

Those images were on my old website, the links are no good any more.

The pics are now hosted on my current website: click here instead.

Eric -- that worked fine ... excellent build pics, made that 67' look beter than new.

Trans is <span style="font-style: italic">almost</span> in...trying to find that last .001&quot; of wriggle room to get the input shaft to go into the pilot bushing...going to have my lovely assistant Rachel work the clutch while I try to get the trans wriggled the rest of the way home.

Four things to note so far:

1) This trans is HEAVY!

2) This trans is BIG!

3) It looks like the shifter is going to fit the factory opening pretty well.

4) I don't advise doing this solo with the car on jack stands unless you're a good bench presser.

More shortly...I hope.

Hi to Rachel!

[VintageMusclecar]

Success!

Now I need to figure out what trans mount this thing requires, acquire said trans mount, then see what I need to do to get the crossmember back in.

The shifter location appears to be spot-on.





Here's the new MW CM pinion yoke next to the OEM unit:



I tried to get the yokes swapped out so I could measure for the new driveshaft but I ran into a small snag--I need to get a new pinion nut to work with the MW yoke. The factory 1 1/4&quot; nut is too big and the socket won't fit in the well of the yoke. I need to pick up an aftermarket 1 1/8&quot; nut from Kammers this afternoon (hoping they have one in stock!)

More soon, but I'm off to get cleaned up. Rachel and I are finally taking a (partial) day for ourselves and we're going to Kil-Kare tonight to watch test &amp; tune...if it doesn't rain. [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img]
