Oil pan swap warning! For those of you swapping your oil pan or oil pan gasket with A4's, DO NOT follow the recommended torque spec on the transmission bellhousing to oil pan bolts!
The recommended torque was 37 lbs for manual transmission and 70 lbs for autos. I went to 37 lbs at first and my gut was telling me to stay there. The internet search told me otherwise and I stripped the threading out of my oil pan. I didn't even get close to 70 before it went.
So pissed off right now. Now I need a new oil pan. Don't make this $200 mistake.

I'm sure. Here's an example of the installation post from another forum. Note #4:
--Installation--
1) Apply a 0.2 inch (5mm) bead of sealant RTV sealer 0.8 inch (20mm) long to the engine block. Apply the sealant directly onto the tabs of the front cover gasket that protrudes into the oil pan surface
2) Pre-assemble the oil pan gasket to the pan.
3) Install or connect the following:
Gasket onto the pan
Oil pan bolts to the pan through the gasket
Oil pan, gasket and bolts to the engine block. Snug the oil pan bolts finger-tight. Do not overtighten.
2 lower bellhousing bolts to position the oil pan correctly. Snug the lower bellhousing bolt finger-tight. Do not overtighten.
4) Tighten the bolts as follows:
Tighten the oil pan-to-block and oil pan-to-oil pan front cover bolts to 18 ft. lbs. (25 Nm).
Tighten the oil pan-to-rear cover bolts to 106 inch lbs. (12 Nm).
Tighten the bellhousing bolts to 37 ft. lbs. (50 Nm) for models with a manual transmission or 70 ft. lbs. (95 Nm) for models with an automatic transmission.
5) Install or connect the following:
Engine cradle. Torque the upper four bolts to 92 ft. lbs. (125 Nm) and the lower two bolts to 107 ft. lbs. (145 Nm).
Side closeouts and bolts. Tighten the bolts to 106 inch lbs. (12 Nm).
Starter motor. Torque the bolts to 37 ft. lbs. (50 Nm).
Oil level sensor. Torque it to 26 ft. lbs. (35 Nm).
Intermediate steering shaft bolt. Torque the bolt to 35 ft. lbs. (47 Nm).
Left and right lower shock bolts. Torque the bolts to 48 ft. lbs. (65 Nm).
Left and right engine mount-to-cradle bolts. Torque the bolts to 43 ft. lbs. (58 Nm).
Oil filter
Negative battery cable
6) Refill the crankcase.
7) Start the engine and check for leaks.

put a helicoil in the pan.

This looks accurate. I wonder why the V6 needs a torque that high but 35 ftlbs is likely spot on. I'll torque to that when my new pan gets in lol. Thanks.
