TRNW-2: 10R80 pump bolts

[Fred Whitaker]

 I have been using the bolts in the precision kits with no problems so far.

I just got 12 new ones from the dealer,  $1.40 each,  the newest ones have a green o'ring on them, some still have the orange o-ring,  I'm putting loctite on the threads  also, just for insurance,  I know I've had to use those ones in the kits a couple times , and didn't have this problem, so I'm not sure what happened, but it's likely I didn't double check them after tightening them initially ?

     Not sure why Ford decided to get away from the aluminum washers they've used on other units ?   or why the aftermarket chose to put that cheap silicone on their replacement bolts ?

  I just had a 10R80 I built a couple weeks ago come back leaking out the front,  virtually all the pump bolts were loose,  I did not reuse the factory ones, but used the ones in the Precision kits,  which have the cheesey silicone applied around the bolt head,   So either I didn't get them tight enough originally ?  which may simply be what happened, I typically put them in with my speed handle, tighten them with my battery powered impact, and recheck them with my speed handle, but I could have been distracted during that process or pulled off to do something else ?  who knows ?

   What are most of ya'll using on these ?  the later design Ford bolts ?  or using these cheesey ones and maybe adding some locktite or adding a dab of silicone ?
