Is there a certain way a 3-speed manual tranny is supposed to go in on a '57 Bel-Air? I'm having a devil of a time getting it to line up properly with the clutch & flywheel!

First of all, if you had the clutch removed and put it back in, did you use a line up tool, or an old input shaft to line up the clutch disc and pilot bushing as you tightened the bolts on the clutch pressure plate? If not, you need to do this first.
Second, place the tranny in any gear and if you have an extra driveshaft yoke lying around, stick it in the rear of the tranny. When you go to stab the tranny, you can turn the yoke to help the input shaft go into the clutch disc. This should make it a little easier. There have been times when I have wrestled with a tranny forever and could not get it stabbed. So, I would get out from under the car, take a pee, sip a Coke and get back under the car and the tranny would almost jump in the hole.

As DZ said, it is very important that the cluth plate was properly lined up with an alignment tool or an old pilot shaft. I have seen pilot shafts, and bearing collars break because of poorly aligned disks. If properly aligned, the trans will easily slide in, with only mild manuvering.

Hi '57,

In addition to the great info previously posted - I hope that you verified the clutch disc "fit" on the trans input shaft.

Did the splines match up? I have seen some misapplications before.

You can visit your local auto parts house - they offer a universal tool to align the clutch disc (a tapered device that centers in the pilot bushing).

I also take some long bolts and cut the heads off. Screw them into the bellhousing. Then slide the trans on the bolts - and WOW - it sure takes a load off of your arms - and allows the alignment process to progress.

Yell, if you need further assistance!

I stopped by Lowe's and picked up a pair of 10" long 1/2" bolts and cut the heads off. The shop manual actually recommends the use of transmission guide pins to assure straight -on alignment into the clutch disk and bell housing. But the clutch disk must be centered in order for the trans input shaft to go through it and into the pilot bushing. I have to note that I just installed a new pilot bushing into my 6cyl's crankshaft (which was formerly used with a Powerglide) and had to ream out the bore for the pilot bushing to fit it in. I also found that the pilot bushing was squeezed somewhat to the point that the input shaft would not enter, so I had to hone that out too.

Maybe that's part of the problem ... I did loosen the clutch plate when trying to align the transmission early on - Maybe something is mi-aligned because of that. Can I loosen the plate again and try to align the transmission that way? I installed some guide bolts to help align the tranny (Thanks, <B>bowtieollie</B>!!) Those really helped alot!
You guys are great!

Yes, you can loosen the bolts again, BUT WHEN YOU DO, INSERT A LINE UP TOOL, OR, AN OLD TRANNY INPUT SHAFT THROUGH THE CLUTCH DISC AND INTO THE PILOT BUSHING IN THE END OF THE CRANK---------------then, tighten the clutch bolts and remove the line up tool.
THIS IS IMPERATIVE, IF YOU WANT THE TRANNY TO GO IN!!!
