A/T 4speed fails, car wont move until hot.
the o2 works , if and only the output swings, about .2 to .8v
this is how it works, the swinging is the ECU hunting, perfection, over and over. the ECU does that, the new 02 is good.
if the exhaust leaks, #4 tube cracks are 90% of this. then it sticks at 0v. and goes rich. and misfires (lower power) and cat gets hot.
and MPG falls.

does water temp reach and hold 180F or more. if not the ECU and TCM will not work right. both.

the last page is here. Cut.
is this not clear, the V mean VAn, or 4doors,

note how it matches yours exaclty, engine./trans, year, doors, and fed, (not calif)
see? AT means automatic version
only works on 16v mpi engines
the calif might work if EGR is changed out and harness rewired, at both ends.
the 1995 wont work for the same reasons (EGR and more)
the B20, B40 and B60 are for older years, and all the smog parts will fail.... (egr is different) it will run, but there are not too many folks trying to run the wrong ecu,
I did for 1 year, a/t ecu in an m/t ,. no problems. seen.
but you cant do that, use m/t on A/t car. or the TCM goes nuts. and TCC fails.

but all this is still moot

we need the data , speed, rpm and slip tests in each gear.
called the manual mode tests....
as i told you ,the trans must not slip (beyond TC normal slip)
the engine must have full power or the shift points will be wrong, (for you)
never condemn a Tranny until engine power is restored.
if in fact it is low... i cant tell , i can't drive it.

subjective to extreme this... (live human tests)

"if it did engaged" (3d)

what you failed to say is what 3rd did,,,?
1: acts like 1 st gear and does not slip , exactly the same, yes then that is 1st . and 3rd failing. (as stated in the fsm and my first post line pressure is next)
2: RPM drops power is horrible (normal) do so on flat ground and see car accelerate, it will be slow, but is in 3rd gear. so.... it will......about 50mph shift to od (Drive)

what matters is speed, RPM and car movement and if it slips.... (a driver sees all those things, I CAN NOT)
you must communicate them to me... or i will tell you wrong.

seems 3rd gear is dead, and that my guess would mean, that normal mode.
trans shifts from 1, to 2nd then stays in 2nd and will never hit 3rd gear, and would not do OD as that be impossible from 2nd.
count your gears, ?
didnt notice , 3rd is missing, (in normal mode)
