WSLADE2.
An update, I had to replace my AI and DG instruments due to a 4-6 week back-order on the bearings, The shop offered new instruments, and yes compatible replacements for the 400 autopilot, for $300 over the overhaul! Still having servo problems, having gifted servos from a SOAPA member checked by Mayday Avionics. If these don't work I'll have to go with (hopefully) serviceable servos from Preferred Airparts at $1700 for both. Or the $2500-$2800 rebuild per servo? I thought I found a new autopilot, S-Tech 3100, but it's not authorized for the C337! I'll keep you updated, and thanks for your support.
Regards.

Thanks for the updates!
I haven’t dug into my autopilot yet as working on hydraulic issues
The s tec numbers are something of a stunner
But, I have kept my 182 and it has s tec system 50. Good wing leveler and will track course after lining things up. Not as capable as the 55 but point is s tec may have some less pricey alternatives....
But still “stout-ish” as will involve new install.

I've got an S-Tec 60-2 in my P-model, fully coupled, with GPSS steering, electric trim, and an Altitude/VS preselect indicator. S-Tec will gladly sell you a new one today, and its got all the right paperwork.

You don't have to wait on Garmin to get a new, modern AP in your Skymaster.

The problem is that for us early model owners (pre D) there are only 3 stec systems STC'd for us......the 40, 50 and 65. You guys with the new models are approved for all of them except for the 3100. The system 65 is outrageously priced and you have to find a place for the roll and pitch computers. I cant imagine that would be a viable installation at all unless you are dropping the money for a brand new Reilly.

I would still like to think (dream) that there will be a lower cost option for us, but being realistic about it tells me that it will probably remain a dream.

My avionics guy said would be around $22k to $24k for a system 50. $13.5k for the unit and the rest installation.
