Fixed my shudder, now a new issue...

Hi guys,

well i just picked up a 97 bird 4.6. it had a pretty bad shudder but mercV in the tc and tranny fixed that. the new issue is that in the process of tightening the bolt to the pan i put indents in the bolt holes and kinda warped the edges of the pan, i was able to strighten out the pan a little bit but i still have a small drip, also two of the bolts got stripped out, how much trouble am i in? what should i do? new pan? can the two bolt holes that where stripped be re-threaded? or am i in super big trouble? thanks guys.

My FIRST question is, why were you cranking them down so tight? The Ford service manual states 106-132 inch-pounds (!!) (IOW, between about 9 and 11 foot-pounds, or pound-feet).

I'd get a new pan. As to the two stripped holes, someone who's knowledgeable on transmissions may chime in, but I'd look for a HeliCoil in the proper size (what size that is, I dunno - take your old bolt in and get it matched.)

If you tightened it so tight that the bolts stripped then you probably bent the heck out of the pan, also I'm going to guess and say that you didn't reuse the reusable gasket or purchase a new ford gasket.

The aftermarket thin rubber or cork gaskets allow for easier over tightening of the pan bolts and dimpling of the bolt holes. Since you've already stripped out the threads I'd recommend taking it to a transmission shop and having them repair the threads and install the correct gasket along with a new pan or straightening out that pan since it sounds like your a bit out of your league on this.

If your handy you could weld the holes, drill and tap them to new, or heli-coil the holes, or time-sert the holes. However it like mentioned before it doesn't sound like this is something your capable of, maybe I'm wrong, I'm not trying to be rude, just honest.

i really didnt feel like i was over tightening them, but i was in fear of leaks so i took it a little far. im trying to source a used pan, but all the salvage yards in my area say the whole trans or nothing, ebay has one for 50.00 shipped but it looks like it might have the same issue as mine from the photos. i am only leaking a drop every so often and im thinking about letting it be for a few weeks and buying a decent pan off summit when i got a little more money. this is my 4th bird and i have done this more times than i can count and never screwed up like this before on the bright side i had a horrible tc shudder that is completely gone and for having 216k everything seems in tip top shape.

-at first i used a cork gasket but i have reverted to a new ford gasket. like i said above i have done this many times with no problems, i just over did it this time, as for welding and what not i have no experience and would be in over my head.

Doesn't Ford get like 36 for a brand new pan? Also just helicoil the 2 stripped holes. You can buy kit from parts store for like 20 dollars.

That Cork or the POS Felt Gasket was your problem.
