Lubrication during assembly

When you get your tranny back from me, the curious like to peek inside. You’ll see a fair amount of lubricants used both to assemble the tranny and to prep the assembly for your installation.

I’ve found that problems can happen when too little or not enough lubricant is used in the assembly. When you are installing the shifter, you’ll want to be able to shift through the gears, and they could lock up if they are dry. This will cause the synchro ring to lock onto the cone of the gear. Not good.

Too much lube can prevent the gear lube from coating the gears under performance, so prudence in appling assembly lube is the order of the day.

When your tranny is hard shifting

Here’s some troubleshooting tips from Old Car Weekly when your T10 is hard shifting:

  • Linkage is binding due to bent, worn, or broken parts.
  • Lack of lubricant in the transmission.
  • Damaged or worn synchronizer assembly.

Noisy in Reverse

You want to back up, your tranny wants to complain. Check these items:

  • Worn or damaged reverse-slider gear.
  • Damaged or worn reverse gears on cluster-gear assembly.

It ONLY complains when you are in reverse:

  • Worn or damaged reverse-idler gear.
  • Worn reverse-idler bushings.
  • Damaged or worn reverse gear on cluster-gear assembly.

Prices Going Up with Parts Becoming Scarce

Over the last year it has become more and more of a problem to find decent trannys from which to re-build Muncie transmissions. I’m paying more for poorer quality parts and that cost is getting reflected in the finished product.

Another problem is that the poorer quality parts require much more work and expertise to re-build. Cases that are torqued are an especially tough (and expensive) problem to deal with.

Leaks Lubricant

More troubleshooting tips for the T10:

If you have leaking lubricant, these are the trouble spots to check:

  • Transmission has been overfilled.
  • Damaged gaskets.
  • Extension housing rear seal leaks.
  • Side-plate gasket leaks due to loose bolts or defective seal.
  • Loose or broken clutch-gear bearing retainer.
