Sounds reasonable.  It was bolted up, but the transmission was replaced.  Sounds like it wasn't reassembled correctly.

Who is doing this work? This is the 440t4?

A guy in Texas is doing the work.  It had an '87 440T4 in it, but that transmission had issues.  The transmission was ”rebuilt” twice, but it developed other issues, so it was replaced with a '92 4T60, which just went in yesterday.  These transmissions should be almost interchangeable, as I understand.

You might want to bring it home for work local to you and call it even before any more $$$. At least locally other eyes can look at these issues for a second, third. fourth, opinion.

I also never had a line "hairline crack".

Just a suggestion.

Also, there is no difference between a 440t4 and a 4t60. The later is part of the newer naming convention for the old transmission; 4= four speed, T= transverse installation, 60=the relative torque carrying capacity.

There are internal differences and running changes through the years of production and there are different torque converters but the difference is in the stall speed/K factor, and not how they fit.

I was unable to find anyone locally who both could and would do this work.  Yes, the distance is a concern, among other things.

No extra $$$, but it sure takes longer.

I'm aware of the change in naming convention.  Thus guy originally put the 4T60 transmission in another Fiero, which I drove.  That Fiero was wrecked this past winter.

Well, the torque converter is the wrong size, supposedly.  It was replaced with the transmission rebuild by the rebuilder.  A vote of no confidence in the rebuilder.  Wouldn't you notice if the torque converter is the wrong size, when you mated the transmission to the engine?

It runs!  It runs, it runs, it runs, it RUNS!

My Fiero drives and shifts nicely.  The kickdown needs to be adjusted, but that should be relatively easy.

2 new problems: the seal on the fuel tank leaks, and the oil pressure is pegged.  A third issue is that the tires dry rotted over the winter to the point of being unsafe.

So....once the oil pressure and fuel leak issues are fixed, and the kickdown is adjusted, the AC can be charged, and exhaust can be fixed, and the alignment done.

The question is, where can I get good NEW tires for an '88?

Check out Tire Rack.  You can have them drop-shipped to an authorized installer near your mechanic and you know what the installation and balancing costs are beforehand.  Use their Shop By Size feature.

I found BF Goodrich tires there that will fit, but pricey.  $1,280, just for the tires.

Prefer Michelin or Goodyear.  $633, installed, with road hazard, installation, lifetime rotation at NTB.

I don't know what size you have, but I have been running Kumho and Hankook on my 87 and Sport Track, respectively.  215/60/15 and 225/60/15's on the 87, but I don't think Kumho offers that size any longer.  At least not through Tire Rack.

Hmmm.  Having trouble locating matching rear tires.

Just wondering, but if you made the wiring change at the oil pressure sending unit, but not in the dash, wouldn't voltage be applied, causing the gauge to max out?

When changing out the oil pressure sending unit there's no need to make any changes in the dash.  If the sending unit has been changed and the wiring was spliced to the new terminal incorrectly, it may cause a problem, but more likely it would be a drain on the battery.  In my experience, a pegged gauge is the result of a bad sending unit or a bad ground.  If I recall, when you unplug the oil pressure sending unit, the gauge will peg with the ignition on.
