    Thanks for all the help everyone has been to me here.
    I ordered a new Rear Output Shaft Housing for mine as the last guy messed mine up with a screw driver badly. Trans kept a small leak and I wanted it fixed.
    I do have a few questions if someone can help me out with it. I have looked every where and can not find the answers first.
    1. What are the torque specs for the Rear Output Housing Shaft for the 2009 Tacoma Prerunner 2wd Auto V6 Trans?
    2. I found out that I have to use RTV Sealant so I went to Toyota and bought the RTV " Seal Packing 1281 Part Number: 00295-01281 "
    Question is how long do I let this set on the housing before installing so it can make a gasket?
    I know that you put it on the housing, and then allow it to set for so many mins and then place this on the trans and finger tighten and then let that set for so many mins before you torque?
    Any help would be wonderful!
    Thanks so much!

    If similar to Permatex’ Right Stuff, let sit for an hour after hand tightening; tighten to torque specs; then let sit another 90 minutes before returning to service.

    These are the instructions but I thought RTV had to sit for a little while before assembly?
    Instructions on box say:
    Clean Gasket Surfaces, Remove all olf FIPG materials. Throughly clean all components and remove all loose materials. Clean both sealing and surfaces with a non-residue solvent. Apply Seal packing, Assemble parts within 15 mins after application ( so no waiting? ) Allow 30-60 mins before driving. Hardens to become rubberlike in 15-16 hours.
    I always thought that someone had to let it kinda start hardening before you apply so it can make a gasket?

    Well, I don’t have any specific information on the the a750e as to the wait time.
    But the front front transfer case on the 4x4 trucks uses the same FIPG.
    I doesn’t say anything about waiting to tighten them down.

    I’ll be honest, if it were me, I’d probably just tighten it down. AND WAIT a a couple hours before I add fluid or drive the truck. Again, that might not be the correct way, but we all have to make choices when we “aren’t sure”. That would be my choice.

    I bet @Bishop84 knows. And his advice would be far better than mine.

    Ok, so I'm rusty, I'm gonna BS before I google the real definition.

    RTV/FPIG is anaerobic sealer and with exposure to atmosphere it begins to harden. So it means, you apply it, you must install within 15 minutes or it will be curing in the wrong form.

    So clean, apply, install, leave it for an hour.

    Orange Toyota FPIG is what's called for on a tail shaft housing. 25ft lbs sounds right.

    I wanted to update and maybe give someone else some help with this as I could not find anything only about it.
    So far *knock on wood no leaks from the new housing!
    Note for anyone that does this the lower 2 bolts on the lower shaft are different bolt lengths so remember and or lay them out the way the come out.
    I done like everyone else mentioned here. I took off the old housing and added the Toyota RTV in a bead around the housing and then installed finger tight then torqued in a cross pattern to 25-27 ftlbs.
    The removal of the old housing:
    Break bolts on housing loose.
    Jack up the bottom trans pan with a jack and use a wooden board on top of jack to soften the force on the pan and to spread it out more evenly.
    Removed the trans mounting bolts to the cross member.
    Removed cross member.
    Removed bolts from rear output housing.
    Love tapped with soft hammer the old housing left and right at the tail to break the seal, removed housing.
    Cleaned surface and removed all old sealant RTV.
    Sprayed brake cleaner on rag and cleaned surface of rear trans where housing mates.
    Applied Toyota RTV sealant in a 4.0-4.5mm thickness around the new housing.
    Then applied same order in reverse.
    Hope this all can help someone else later on.
    While I was there I replaced the trans filter and cleaned pan after I installed the rear housing.
    Thanks again guys for the advice here. Tacoma World is Awesome!
