UPDATE:  October 24, 2017

W-56 1986 transmission input shaft housing.

I thought I’d share this information for those that may be interested.

I realize that the subject of sealants and gasket RTVs appears to be a personal choice based on individual experience.

In the absence of my own personal experience, I tend to go with the “technical experts” and the people who use the products in their businesses.

Permatex Ultra Grey is used by Marlin...

For this application, Permatex Ultra Grey is recommended by the Technical Service Manager/Associate Innovations Manager at Permatex for the gasket and housing plate.  He recommended Permatex Thread Sealant with PTFE for the bolt threads because the bolts/threads are in contact with the gear lube inside the case.

He also said to allow 24 hours before filling the transmission with gear oil to allow the sealants to cure properly.

My research also showed that the specification for Toyota part numbers for a number of sealants that Toyota recommends is covered in the Permatex Ultra Grey specification.

I believe that Toyota’s Orange FIPG sealant RTV is an excellent and logical choice.  However, the availability is limited and about 90% more expensive than the Permatex alternative.

I highly recommend that any time you drop the transmission that you replace the input shaft seal and gasket if it has not been recently replaced.  For the cost of the seal and gasket $13.40, the Ultra Grey - $7.99, the Thread Sealant w/PTFE - $5.29 – for me it’s just not worth having to drop the tranny again to fix the leak from the seal, gasket, or bolts.  The leaking gear oil onto the bottom of the bell housing got blown around and onto the pressure plate, clutch disc, and flywheel.  I am replacing the clutch disc.
