dtrentr Posted February 21, 2009 Share Posted February 21, 2009 dropped the tranny pan on my 91 loyale with the 3 sp AT and had no problem getting the tranny filter off, bunch of 8mm bolts and 3 10 mm ones toward the back. My problem is that the two short 10mm bolts went back in fine, but the longer of the 3 isn't screwing into anything, it's like it's not grabbing hold of whatever it's supposed to screw into. What am I missing? I've stff to no avail. I know I just can't stick in a loose bolt in a transmission and hope that it heals itself, is there something that bolt is holding onto that I've moved somehow? Help please, my daughter turns 16 Monday and this is her present! Anybody got any ideas, I've worked on it for an hour. Link to comment Share on other sites More sharing options...
idosubaru Posted February 21, 2009 Share Posted February 21, 2009 Sounds like the bolt hole is stripped, you should have seen some metal in the threads of the bolt you removed. Easy to strip physically, but hard to imagine happening since it's inside the trans, sealed, and isn't corroded. Are you sure you're putting the right bolts in the right holes? The "filter" is the right one? You are absolutely right not to leave a loose bolt in your trans, that sounds like a really bad idea. Here are a few options: 1. If it comes to it being stripped, which it sounds like it is, then you have a couple options. The easiest if you're lucky is to just use a longer bolt hole. Often the holes are longer than the bolts, just a part of the manufacturing process. So a slightly longer bolt will reach "new", unused, and unstripped threads. Tigthen very carefully and use non-permanent lock-tite. I've done this a number of times, but not in the trans. 2. Some filters i've seen have more bolts than i can count too. If that's the case here, you might just not worry about installing that bolt. The "filters" usually just have one small sump side with the oring, the rest isn't a sealing surface at all. If it has 10 bolts and this one is no where near the oring, I'd probably do this. 3. The other option is JB Weld or permanent lock tite. Clean the hole out first with brake cleaner. The permanent locktite isn't a bad idea if you have enough for it to hold onto based on the following information: It might help to know this. Pretty sure the 3sp transmission is just like the 4EAT trans also offered in EA vehicles in regards to the transmission filter. If so, there's absolutely no need to ever replace it unless it's damaged. It's NOT a filter eventhough it's called that. It's a screen and they never get dirty...if a screen gets clogged you have far bigger problems than a clogged screen inside the trans. happy birthday to your daughter...hopefully...

dtrentr Posted February 21, 2009 Author Share Posted February 21, 2009 nothing stripped that I can tell. I'll try the longer bolt and see if it's just pushed something up and maybe another inch will get there, otherwise I'll leave it out and hope for the best. It looked like the tranny pan was seeping so the gasket was in order, for $7 wth, it sure needed the fluid changed. Off to NAPA when they open, gotta get this thing on the road, I figure on Monday it won't ever cool off long enough to work on! Link to comment Share on other sites More sharing options...
