This is on a 96 LandCruiser a343 automatic transmission. Dropped the pan and replaced the filter last week. Wanted to do a drain and fill this week. Removed the m10x1.5 drain plug via 14mm bolt head. All seemed fine. Drained out about 6qts. Cleaned it and went to reinstall the plug with a new crush washer. It didn’t want to overtorque it, but the bolt wasn’t cinching down as I tightened it with my torque wrench. I went to loosen it and no dice. It just spun.
I tried a number of things, but eventually had to drill it out partway, which let us remove the plug.
Went to parts stores and it’s hard to know if an m12 will fit. I found m10x1.5 flanged bolt (same as the plug) that wouldn’t go through the drain hole. A 7/16-14 would have been better but searching for this on a Saturday pm was becoming g a wild goose chase.
I tapped the hole for m10x1.5, which was the OE plug. I used a new flange bolt and it has held. I torqued carefully up to 12 ft-lb without issue.
So far so good. It torqued to 12 ft lb which is enough to crush the washer. Wasn’t going to get a time sert or anything on Saturday night. I’m not sure there’s enough meat to do a time sert anyway.
It isn’t loosening or leaking. Should I be concerned?
I’m concerned that drilling out further will be detrimental.
Any thoughts how durable the current setup might be?
There isn’t much that can be done…
