Good. Use some anti-seize compound on the threads when you put it back together and they should stay that way. 50-60 inch*lb for the pan bolts is what I think I remember reading somewhere. It isn’t much.

Last time I did a transmission pan gasket on an AW70 it was something like 8-10 ft-lbs.

The book said 36-39 in lb. which seems awful low, maybe a misprint. Most M6 bolts on transmission pans are 80-90. Went for 70.

I just checked the Bentley Bible and found the same spec. It's much higher with the paper gaskets. The low torque spec is to keep from distorting the pan and squeezing the gasket out between the bolts. I usually go with 60 in*lb as a happy medium between the specs. 36-39 in*lb is so low I'd be concerned the bolts might back out. Make sure to re-torque the bolts in the next day or two. Once everything heats up that gasket will compress quite a bit.

The book says 4-5Nm.

Too loose, they will loosen at that torque. Try 7Nm

Eidt: the spec for AW70/71/72 is 4-5 Nm. The following is for BW55/AW55. Whoops.


The 200 series greenbook has different torque values depending on the color of the gasket?

The 700 series greenbook only shows the 4-5 Nm (3-3.5 ft.lb) spec.

Used a Toyota gasket to 70 so hoping no leaks.
