I am about to change my transmission pan and gasket for my 190E. I read that the torque specs for the pan bolts are ~106 in/lb (my mistake ~106 in/lb is not for the 190E, but for the 1997 C280, I got this info from the resources tab in the DIY section for transmission fluid change) however I do not have a torque wrench. Should I tighten it right until I feel it is tight, and then give it another quarter inch turn? I ask because I have bought 3 gaskets and this is my second pan this month (actually last month in June), but the first time it was uneven, which I didn't realize and so I over-torqued, splitting the gaskets and warpping the pan. My pan and gasket are scheduled to be delivered today. Thanks

I suggest you guy buy a torque wrench then. Correct Torque settings are imperative. You have already experienced why as you said. They aren't too expensive.

The 190 will have the 722.4 tranny, which uses the same pan as the 722.3...8nm.

Here's a good quality torque wench for small fasteners you might want to consider-

Good luck.

I'd use a 1/4 regular length rachet... if I didn't own a small torque wrench.

I'd suggest just getting a harbor freight 1/4 drive torque wrench for $20 plus or minus depending on sales.

Remember if you get the 25-250 in-lb one- it is not accurate in the bottom 20% of the scale or the top 10%. So, it's good from 50-225 in-lbs.
