I have a working spare MD755013 from a ’93 I’d be willing for you to try, if you were close enough to me, but man your closer to New Hampshire than southeast Virginia. Maybe someone closer to you with proper part# unit might see this and offer one up for a test.Scotia, NY - a little town in Schenectady county just west of Albany.
I’ve also called around to shops and so far, nobody really wants to work on it… these cars are getting tough to service unless you DIY aren’t they?
Reason it’s hard to find shops willing to work on these transmissions, is they require someone with previous experience with these particular transmissions. As you mentioned they were complicated with electronics in early 90’s before sophisticated troubleshooting devices to point repairmen in correct direction. Unlike later years as sophistication advanced so did the advanced electronic troubleshooting support devices.Well, I called around to some transmission shops. First of all, nobody really wants to touch this car… it’s crazy! I know they were super complicated in 1995, but are they really that complicated compared to a brand new car, even a more pedestrian one like a Civic or Accord?
The shop that originally rebuilt the transmission in 2014 for the previous owner is going to take a look at it though. I just loaded it onto a flatbed to get brought up there. We’ll see how this goes!
............ And honestly, I couldn’t even find a valve body, and looking at a picture of it, I have zero confidence in my ability to do a DIY rebuild or even cleaning.......
Yeah, it will be pretty annoying if another rebuild is needed - I checked the Carfax again and it turns out it's been LESS than 4000 miles since the rebuild. The previous owner had it rebuilt in 2014 at around 114k. I bought it from him in 2017 with 115k, and I'm now at 117,800. (I have the 3000GT insured through Hagerty as a classic, so I'm limited on miles anyway, and I also only drive it on nice days. I also drive less these days).Reason it’s hard to find shops willing to work on these transmissions, is they require someone with previous experience with these particular transmissions.

Hopefully original transmission service can locate problem without another rebuild being required. Wishing you luck with this move.
No you wouldn’t want to take on a valve body cleaning or rebuild, they have many parts and pieces including even small steel balls in some that fall out when disassembled. You’d have to know where those balls/etc. go in order to get it reassembled correctly. And that description is of valve bodies I messed with ~ 5 decades ago with no electronics, just mechanical linkages and some occasional vacuum modulators.
Rebuild should last as long as original if done right, mine was rebuilt at ~ 111K and now has ~142k on it, so it’s lasted ~ 31K so far with no signs of failure yet. With the exception of TCU failure which wasn't caused by the rebuild.it should have lasted far longer than 3800 miles, unless rebuilds have a tendency to not last as long as factory-original.
Name of service provider is not as important as ability of person doing the work. It sounds like the guy from Aamco has a more logical approach than where you have it now, never heard of transmission service that wouldn't check valve body without a complete rebuild.I also called Aamco (yes, I know, but our local one has gotten pretty good reviews)… I got a great vibe from the guy I talked to. He actually seemed to surprisingly know about the 3000GT and F4A33 transmission, and when I described my symptoms he immediately thought valve body or solenoids. He said even if they had to do a full rebuild it would be $2100, and if as he suspects it’s just the valve body it would be less than that and if just solenoids, even less and DIYable.
