Which they took your Amsoil and used in their own car and did nothing but gave you time to get a second coffee
. Which is what I would have done if you went off on me. Not everyone is intimidated by that. 
Have yet to find sludge, but not totally uncommon to find coolant from a failed radiator heat exchanger. This also causes transmission fluid to migrate into the cooling system. Blocking passages in the valve body or solenoids may be a possibility. As the clutch discs wear the friction material remains in suspension in the fluid. With a high mileage transmission this is a good thing actually adding friction to the clutch packs. Flushing the fluid removes the friction particles and can cause the transmission to slip, burning the clutch packs, and well you know the rest. Examination of the pan and magnet will hopefully show only fine particles and no bigger pieces. Regular fluid and filter changes started early will be a lot more advantageous using a quality filter and the best quality fluid for the brand. If it doesn't meet the OEM spec, it shouldn't go in. There is a reason I stock so many types of transmission fluids, engine oils, coolants, power steering and brake fluids in my business.
A one day rental of a medium size forklift? I rented one for a week while erecting a steel building and it was reasonable with a quick learning curve. Yes the lift was too heavy for my little tractor, so we used it to pick up one end while the other side was lowered by the lift gate. I had a great delivery driver.I'd have a 4-post now if I had a way to get it off the truck. They won't drop it with a lift gate, and it weighs too much for my tractor w/FEL. They said have it delivered to a business and pick it up with a trailer. I said, I don't have a trailer and how would I get it off the trailer if I did have one?
WOW, not here. Depending on vehicle, $125 - $200 or more. Couple jugs of T6 will run more than $50 and a Motorcraft Diesel oil filter is maybe $25. Without an upsell, I still need to make something for my labor. And I use a torque wrench on the drain plug. DIY is fine as long as the OEM service recommendations are followed.You were hosed. In our region there is a chain called Prompto. Most full synth oil changed are in the neighborhood of $50. Looks like $90 for something STR specific.

I wonder which will do more damage to your car... OEM-spec oil in place of AMSOIL, or being a dick to your mechanic?
What do you recommend for low-mileage vehicles? Some of my sports cars see less than 3k miles per year, so it can be a decade before I hit the mileage recommendation for tranny or diff oil changes.

Short of our members who may be getting too old to crawl around on the ground under a car, or those otherwise injured/disabled, I have a lot of trouble understanding anyone handy enough and with the facilities to be into tractors... but somehow unable to change their own oil in their own car. Do they hire an electrician to change their lightbulbs, too?!?
It takes all of 20 minutes to change oil on a car, literally removing one bolt and unscrewing one can filter on most, then replace bolt and filter, and pour new oil in. If it's a pickup truck, you can even skip pulling out the ramps, and probably get the job done in under 15 minutes, if you hustle.

I do engine oil and coolant on a calendar schedule on low-mileage vehicles, yearly and six years respectively, but usually go just by mileage for other fluids. Not sure if that's best, but it has always felt logical.
