A few months ago I had the transmission fluid pan on my '99 LC replaced at a local Toyota dealership (long story). The other day, I noticed that my transmission dipstick tube had some play and it rocks back and forth a little when I insert/pull out the dipstick. When I looked from under the vehicle, I saw that the dealership did not put back the bolt that holds the lower filler tube bracket to the transmission housing (?). A closer look showed that the hole where the bolt goes in on the bracket does not line up with the hole where the bolt screws in to the transmission housing (they are off by about 2-3 mm) so I believe the dealer just left it out instead of trying to line everything back up and put the bolt back in. Instead of taking vehicle back to the dealership and risking them taking a shortcut and force/bend the lower bracket or the filler tube over to put the bolt back in, or worst yet they screw the bolt in a little crooked and strip the thread, I'm going to try to get the bolt and put it back in myself and call it an educational opportunity.
My questions are that:
1) Does anyone have a part number for this bolt? It's the one for the lower bracket on the transmission filler tube for a 99 LC. (please see the red circled item in the photos)
2) Is it a good idea to replace the o-ring on the end of the filler tube that goes into the tube on the side of the transmission fluid pan? I'm sure that mine hasn't been replaced for a while, but I just don't know how often this o-ring needs to be replace. I know many members on the forum frequently service the transmission by dropping the pan so I was wondering if people routinely change out this o-ring. Does anyone have the part number for the o-ring?
3) Once I get the parts, I plan to undo the bolt that holds the upper filler tube bracket in place so hopefully I can adjust the position of the lower bracket to put the bolt in. Anyone knows how much flex I'll be able to get from the filler tube or is it really stiff? My concern is that once the lower bracket and bolt is on, now the upper bracket and bolt will be misaligned and not be put back in place.
4) My last question is nothing to do with the above, but has to do with the ATF level. What's the "normal" operating temperature of the ATF to properly check the ATF level? When I checked the level yesterday after driving on the freeway and the ATF temp read 150 degrees on the scan gauge II, the ATF level is only about 1/3 into the hot zone. The hottest I've seen my ATF temp is 179 and that's when I'm stuck in traffic and going up a long hill on a day with 95-100 degree outside temp. Normally on the freeway the ATF temp is between 140-160, so am I assuming correctly that around 150 is the "normal" operating temp where the fluid level is supposed to be at the top notch of the hot zone on the ATF dipstick?
Thanks for any input and help!
