Hi guys,
I am trying to figure out if I can reseal a TII tranny. It's not leaking at the rear shifter housing (where I already sealed it), it leaks at the plate before it. Do I need any special tools or is it pretty simple to remove that plate? Or should I just take it to a shop and have them do it?

Ok, a quick look at the FSM, it says I need to remove the shift rod ends and then I can pry apart the "bearing housing". Is it really that easy?

yes and no, you have to pay special attention during both disassembly and assembly.

Thanks for the quick response. What specifically do I need to pay attention to (on removing the bearing housing specially)?

take all the sensors and detents/springs out of the shifter housing then drive the roll pin out of the shifter bore and remove it then you can slide the housing off. when assembling it you have to try to keep the shifter aligned with the notches in the forks.

Thanks for the info. I've done the shifter housing before so am familiar with the process for that part...good info for others who are unfamiliar though.

you won't really need any special tools unless you plan on taking the gears out of the case so you should be good. once the tail housing is off, iirc the only thing you need to remove to get the center housing off is to remove the shift fork ends.

if what i see is your transmission solidly mounted to the crossmember, that might be one reason why you are having the leak.

it's not. i have custom mounted it due to this going into an FB but it's not "solid". i believe the leak was already there, exacerbated when i had to change the shifter housing. will see if i have time to take it apart tonight.

Removed the shifter housing(TII one is different than what is pictured as I'm using a 12a shifter housing to fit into the FB). "Right stuff" definitely makes it harder to remove things. Then removed the 3 shift rod ends and popped the bearing housing off. Need to clean everything up now and figure out what kind of RTVto use. I can't use "right stuff" unfortunately cause it cures too fast (your supposed to have it torqued down within a minute I believe). Need time to install the shifter rods as well as the shifter housing...I need at least 10 minutes to make sure I install everything properly. If anyone has any recommendation on the kind of RTV to use, please share.

anaerobic sealant, though it's not for sale at most automotive parts stores. we used to use it on gearboxes when i worked for dodge, so they would likely have some. (dodge, chrysler or jeep dealer)

like this:

won't harden when exposed to air, it will however only give you one shot once you bolt everything down as it cures immediately once assembly begins.

Yeah, I saw that when I googled anaerobic sealant. I've decided to go ahead and use permatex ultra black as the cure time is 24hrs.

Thanks for the help btw!

i think if you want to make sure it doesn't leak again you should use the proper sealant, i have had issues with silicone sealants and these gear boxes before.
