Help Identifying Leak Under MH?

In that area the transmission can leak around the small red filter, where the oil cooling lines come out on the passenger side, as well as at the lower pan gasket.
You may have to get underneath and clean everything to find the exact location of the leak.
As mentioned, I would try tightening the pan bolts an extra 1/2 turn. You do not want to over-tighten them which may distort the pan and make it leak more.

Yes, sir, thank you. I'll check that area as well. From what I saw, at least 1 of the pan bolts had a drop on the head. And there was a drop at the bottom of the pan near the drain bolt. I do have a torque wrench so I'll check the Allison manual first before tightening.

Have you ever had the fluid changed by dropping the pan? If so how long ago? There is a sequence to torquing the bolts also. The last time I changed my fluid I used the new rubber gasket that came with the filter kit because the OEM filter was 20 years old and looked stiff. That was a mistake I could not get the pan to stop leaking with the new gasket. The original gasket had steel inserts around each bolt hole that prevents the gasket from deforming when bolts are tightened. After a week of trying to re torque the pan bolts run engine and checking for leaks I put the old gasket back on and all was well again. Just make sure the leak is not coming from above the pan gasket and running down the sides to the bottom. Good Luck and welcome to the forum.
