Transmission (Dual Range C6) Rollerization and Build up - Assembly Part I

Hello again,

OK, so we're putting it all back together now. If you're doing a stock rebuild, just remember in this where I show Torrington's just replace with the correct flat thrust washer from your rebuild kit.

Right, let's crack on...

These are the only two bushings left in the case from last time. It's important to remember where the notches and oiling lines are facing. Also lube up the area with Vaseline or ATF.

Using the appropriate size seal/bearing driver drive the back one to the front and push them both out.

At this point I chose to detail the case with some high temp engine paint.

Again, lube the bushings and area. You'll be driving the front bushing in first so align it carefully and use a rubber mallet to start it off evenly, then use the driver to set it and then do the same for the rear one.

like so

Next take the rear race and with some 320 grit make a cross hatch pattern across the radius.

The reason why is to allow oil to lube the surface better between this and the roller in the one way sprag. Remember two perfectly polished hardened pieces of metal can "ring" together otherwise and you do not want that with moving parts.

Clean and set that aside for now.

Clean the rear case piston (Low-Reverse Clutch) and replace the two old seals with new ones. Again, lube everything, can use ATF or Vaseline or both.

Again lube the piston bore in the case and noting the oil bleed hole install the piston.

You can lightly tap it down, notice I'm use a light hammer and a plastic drift as not to cause damage.

Now we can install the rear race, note the oiling hole location.

Make sure the race is evenly seated, it's a tight fitting lip it sits on and once seated should be able to rotate freely. Rotate to line up the bolt holes and torque gradually in sequence until you reach the final torque value.

Replace the springs. Again everything should be clean and lubed. Can't stress that enough!

Apply the spring retainer.

Compress the springs and place the retaining snap ring in place. This spring compressor was only 35 dollars new and is well worth the money. You can make you own but 35 dollars is a small price compared to the rebuild kit, so why not make life easier and it's easy to use, even for being China special.

Make sure the snap ring is properly seated all the way round.

Place the rear Torrington on the case. Again, clean.... lube...... waffle waffle waffle

Place the parking gear on top.

Insert the parking pawl pin.
